My 2276cc Build Process (Combo recommendations welcome)

[16sec65]

I am starting to buy parts for my 2276cc engine that will go into my 65 bug. For those of you that don't know me, my name is Sam Duncan and I'm 19 years old livin in sacramento. What I am trying to get out of this engine is mainly strip, occasional street here and there, no long haul journeys(the track is about 15-20 min away). I want to comfortably be in the mid-low 12 second range with slicks, once I upgrade to a 3.88 R/P(currently 4.37, super diff, 091 idler, IRS case, SAW axles). I am doing this engine in the "cry once" fashion. Meaning all parts will be new, with the exception of a few things(Berg equalizer pulley, Berg oil pump cover). I have been asking questions and looking at different combos and have come up with this so far as to how i want to build it:

AS-41 case, full-flowed, clearanced for 82 stroke, bored to 94, shuffle pinned
82 CB performance forged crank
MAHLE forged 94mm P/Cs
Engle FK-8 or FK-10 not sure yet,
with 1.4 rockers(i'll shop around for best brand)
Havent fully decided on exact heads but I want a vw casting(CB 46x37 ultra wedge port, 044 44.37.5 full port and polish etc.) I want somewhere around 10.5-10.9 Compression ratio.(pump gas would be cool).
Hope to get ahold of a set of 48 IDAs.

Thats what I got so far. I plan on buying the case from TDC parts next week and would like to get some feedback on this setup and if anyone has had a similar setup, would you recommend it for what i am trying to get out of it.

I know that this will be a pretty big step-up from 15s to hopefully 12s but please dont criticise or judge me because of my age. I have been around this sport since day 1 and have been racing since i was 16. (dirtbikes since 13, but thats irrelevant.  ) I am doing this with my own money, the same way i built my 1776. I am not a kid that just wants to go fast. All feedback welcome and appreciated. Thanks and Happy New Year!

With no parts yet, I would like to see about sponsorship for parts. I won sportsman at sac BOR 58, 2nd round @ 59, and 2nd round @ 60. I race at least 2 wednesday night street legals a month when they run from feb-nov. Anything would be appreciated. Thanx again 

[purplecoffin]

Might bump to the k-10, I have a k-8 w/ superflos and 48's and feel that it pretty mild for the track.  (I'm going bigger this winter.) 
There are alot of guys on here w/ more runs than I so Hopefully they will chime in also.  My .02, Don

[maui]

FK87 w/1.4s or near that.

[Jason Young]

SLR Cams xr320 w/ cb 1.4s

you wont get mid-high 10's on a k8 or k10 without race gas, and both those cams are pretty tame when it comes to racing

[16sec65]

I have heard that the FK-87 is not very effective til about 3000-4000 RPMs, which I'll keep in mind.

SLR Cams xr320 w/ cb 1.4s

J, is that the cam that you are using? Recommendations for heads?

[Jason Young]

my cam is a modified version of it, we started with that cam profile and changed a couple things.

i really dont have any recommendations for heads other then talk to the head porter you plan on using.

i have Brothers Machine Shop welded heads w/ 44/37.5 valves dual springs

[16sec65]

I will keep all that in mind. I am going to buy an AS-41 case tomorrow hopefully and then ship it off to Rimco to get all of the case machining done:
Bored for 94s
Clearanced for 82 stroke
Lifter bores sleeved(alum)
Oil galleys drilled and tapped(Full Flow of course)
Groove cut for steel cam plug

Who sells the cheapest AS-41 case?

Sam ! vee dub parts unlimited 714 848 8868  has good pricing and they are right by rimco could have all your machine work done then ship could save time and money. your race advisor steve. good luck buddy remember GO BIG OR GO HOME !

[Jason Young]

i would call brothers for the case, i think they do EXCELLENT machine work and they do alot of machine work for some household names too

Household names Jason who ?  j/k they also do good work. I have herd good about brothers.

[Greg G]

Buy the case from whoever you have do the machine work, that way they can check it all out.

Buy a pair of Steve Timms Signature heads. Charles Deguair in Hawaii had a new pair for sale a while back. email him to find out if he still has them coxc004@hawaii.rr.com or order a set from Steve.

Buy either a FK-87 or 89, if your car will weigh more than 1900# with you in it go with a 87.

10.5:1 compression with the FK-87 and pump gas or 11.5:1 with the FK-89 and race gas/pump gas blend.

No less than 14lb flywheel, weldmate or wedgemated.

Scat I beam rods 5.4 or 5.5 length.

CB crank might be the best for the money. 82 or 84 stroke will work.

CB 1.4 rockers

You will need a trans built to make things work and last.

[16sec65]

So heres where I'm at now.
CB 82 Super Race Crank and Lightened flywheel (probably buy both from same dealer at same time)
I have been recommended to Demello full circle but those seem like alot (i'll keep in mind)
I'm pretty sure now, based on more than a few recommendations, that I will go with an Engle FK-87 with CB 1.4s. I dont want to HAVE to run race gas, so the 10.5 range seems to be where I want to be.

[jays57]

Not a full circle!!!

[16sec65]

Your right, not a full circle. sorry.  Anyone know where to find demello cranks? Feedback? All I'm hearin is CB Super Race Cranks

[jays57]

DMS, (714) 898-7405

[16sec65]

Thanks Jay.
What is the benefit and/or downside (if any for both) of going with an 84 crank? I have heard that more machining needs to be done which makes the case weeker.

[jays57]

There is no downside to a bigger crank!  You could get one with chevy journals to help with clearancing a bit.

[Mike Soliven]

You set on heads yet? you cant beat the CB wedgports for the money IMO! Ive had great power and success with them. I cant wait to do a strung out street motor with them.

[Jason Foster]

 ditto on the FK87.  I run FK10 on the street. 11.0 to 1  mixed fuel.
 wedge ports are good to but may need some chamber work to clean up.and probably need flycut.
 berg oil pump,   26mm.
 CB crank should be ok. I would suggest an 84 if crying once I run demello welded 86 with no probs.DPR also good.
 5.5-5.6 rods good H-beams with ARP 2000 bolts.   
 chromemoly pushrods.
 scat 1.4  or bugpack.
 bugpack straightcuts. or magnum
 might want to cut case for sandseal also unless your pulley is non sand seal. since you have the berg allrready.
 48 IDA's  match port manifolds.
 chromemoly head studs.
 get the lightened flywheel 12- 12.5lb and a good gland nut. and wedgemate it.
 
 Keep us posted.   Jason Foster

[16sec65]

FK-87 is a go!
CB 84 crank chevy journals and lightened flywheel is a go!
CB H-beams 5.5 w/chevy journals and ARP2000 bolts is a go!

How about bearings? Lifters? What are the BEST ones?

Yo Mikey.
I havent decided on heads yet. I'm goin step by step. I have thought about CB CNC Ultra Wedge Ports  But arent sure if they will work best with my combo as of yet. Whichever I choose, they will definitly have major port and chamber work done.

Buy those heads and have Pat Downs @ CB clean them up by hand.

[J. Matsko]

you should actually buy the heads first have them flowed then get the cam that fits the heads full potential.

good luck.

Jerry, could you e-mail me. I have some work for you to do.

kolbenschmit (spelling?) main bearings  double thrust cam Berg or Bug Pack. Bug pack rod bearings.
  I use AJ sims lifters they seem very good to me.   I have 28mm with oil hole with FK10 28mm should be good for FK87 also. They also have 30mm but I dont think you really need 30's. CB performance lifters are good also but you have to disassemble them and clean B4 use.   or you could try Scat but I wouldn't anymore.

[Greg G]

I am partial to good used OEM lifter, but I have good luck with just about any manufacturer of lifters. I have all my lifter re-ground reguardless of who makes them. The only ones I don't like are the newer ones that are not finish machined under the mushroom.

You should be able to run the CB wedge port right off the shelf??

[2332 baja]

Will a wedge port handle the lift of a fk87 without coil bind? For some reason,,,, I'm thinking that about 520 is max lift for an "off the shelf" wedgie. Not sure where I heard that though??? Can someone help me out here? I have a set of the oval ports and want to change cams but I'm not sure how much lift my heads will support. I DO plan to measure,,, of course,,, but I'm sure someone already knows the answer.

[VRT1]

go to a fk89, 1.40 rockers, set the compression at 8.0-9.5 a set of ultra mag plus 44 X 37 or similar and you'll be happy. you might need to get the p-rod holes in the head enlarged and run the CB Racing p-rod tubes for clearance. use the o-ring supplied over the p-rod tube head side first then the p-rod tube seal after the o-ring. this is a trick i tried and it works. p-rods don't rub the tubes. this might not be necessary if you use flimsy p-rods but if you use the good p-rods this will be necessary. reason for the fk89--you may as well spend once. just my 2 pennies

[VRT1]

oh, almost forgot you most likely need to check for coil bind....... physically.

With a valve and spring upgrade that CB offers coil bind will not be an issue. Im running CB's 2289 cam which is the equivalent of a FK-87 with the valve and spring upgrade. If I remember right im getting .575 lift with CB's 1.4 rockers, I do believe the Ultra wedgports already have incorporated the spring and valve upgrade with those heads.

[scott s]

go to a fk89, 1.40 rockers, set the compression at 8.0-9.5

  An FK-89 and compression that low will be a dog. Big cams need big compression. Will it run? Sure. But you'll have a very soggy bottom end and will be giving up lots of power.
 The FK-87 needs ~10:1. The Fk-89 needs even more, IMO.

[16sec65]

I am thinking of steeping up the displacement to a 2332. I have talked to my Trans builder and have decided to have him be the head porter and more than likely assemble the short block. We are going to go with a different cam (not exactly sure yet) But it will put me in the 10.5 C/R range and will be ONLY for pump gas. I am buying the case through him and he is also doing all of the machining for it. Heads will have 44x37.5 valves with full porting/polishing. What about Carbs? obviously 48 IDAs, but what about 52s? Jetting? Updating?

[Mike Soliven]

If you have the money for 52's Id say go for it. If not than the 48's will do just fine.
