Hi..

It's rebuild time this winter/spring and I will go for forged stuff, for a future ATI 9psi kit.

Should I go for 355 or 383?? and what comp. do you recommend?
Which setup will give me least trouble?

If I go with 383 I think it will outflow my heads,TB and I have to buy a new PROM and alot bigger injectors too..

How many rpm do you want it to run? If you build a bottom end torque monster, you should be alright. If you want to rev it and make some high rpm HP, you will want better everything to match the engine. It's all about the combination.
If money is no object, build the biggest motor you can--it's easier to make lots of power and still be streetable.

The cost for 355 or 383 is almost the same...

I think I'll stay at 6000 rpm's max..

 

Be Differnt, 377!
