350/255 Chevy

Sounds like SS/LA? If so, not an easy index in my opinion.
Tough to do with "stock" heads. I attempted a set of "budget"/non welded 441 heads once. I still needed long valves and shaft rockers.

What rocker ratio is your cam designed for? Shaft rockers might be your only option.
I like your idea. If you have a bunch of upgrades to do for Stock, explore your options with a few more upgrades. You're never going to set the world on fire, but you need to run the index and avoid heads-up runs. Can you do that?

Read the rule book extensively..
Been an NHRA member since 1970.
In SS car can fall in L, M or N.
Know it can be a K/SA maybe a J/SA
Figured Shaft Roller for stability.
Would confer with John at Bullet Cam what would be best parts.
Just did not want to carve up a set of 441 heads.
They are not as available as in the past.
Hoping well prepared Stocker heads would be compatible enough.
Can a 2 bolt main block prepared for stock live in a Super Stock Engine.
Or do you need an aftermarket block and just start over..

The Stocker pistons will not have valve notches that would work with a SS type roller cam. Not even close.

[Alan Roehrich]

Yes, a Super Stock profile can be ground on a stock journal cam core.


No, you will not have nearly enough piston to valve clearance with Stock Eliminator pistons and a competitive, even marginally competitive Super Stock cam.


No, legal Stock Eliminator cylinder heads will not be competitive in Super Stock, and no, they will not likely work with the appropriate valve train for a Super Stock camshaft without major modifications.


And no, the short block you describe will not withstand running it like it is a competitive Super Stock engine.


Do yourself a favor, and build a good legal Stock Eliminator engine. Consider a combination that isn't utterly flogged to death.

Dan, why don't you just do a 350/250/230 and call it a day. You can use all of your 255 stuff and it fits into O/P/Q so not a lot of heads-up stuff. All you'll need is an intake and the right carb.

O/P/Q Stock, correct? Once he cuts the spring pockets for roller springs, his 441 heads he doesn't want to "carve up" aren't good for stock anyway.

I considered that but sold the 2v intake and carburetor !
In O/SA would be fairly light.
Not have to worry about a roll bar and fancy seat belts..

Yeah do not want to cut up a set of Stocker heads.

What Billy said would certainly be the easiest way to get out. it will live a long time with a 2GC I have not looked in a while, but I think 230 is now 226. If it was light in O, you would really have to load up to get to Q. I think P is the way to go at 13.45. Good Luck

Do the 2Bbl stocker,just the changes you would have to make for a budget SS engine would cost more than a complete decent stocker engine. Been there done that.
