ok, im going to start my 383 project soon. but would like a few to look it over.

scat 9000 3.75
eagle 6" forged rods
SRP forged pistons
4.020 11.0 -5cc #138096
4.030 11.0 -5cc #138093

Fel-pro head gasket 4.125 bore .039 compressed

Zero-deck at 9"
64CC afr 227s
custom cam (nothing yet)

CR 11.10:1
Quench .039
displacement 382.67
running about a 175 shot

does all that look ok?
anything need to be changed?
thanks

 

what exactly does a 4.125 bore come out to? why wouldnt you just go .030 over?

 

 

should i go w/ the 58cc head take it to 11.8:1

 

You looked into what the AFR 227s take to run? LOTS of special parts.

Offset rockers, offset lifters, adjustable gudieplates, offset girdle blah blah blah. Adds up quickly.

 

....thats the head gasket bore....

 

more compression??? depends on how it will be used and gas availability. This is an ongoing debate. How much compression can someone run with premium 92 or 93 gas without pissing off the knock module?

 

NO, i had the understanding they used
STD. parts so i guess the 220s
the smaller runner is better anyway.

 

Ya their website is very misleading. I was going to get the 227s too until i found out about all that. The 220s should work quite well too.

Forget trying to figure out static compression and what pump gas you can run on it. Pay attention to your cam choice, and figure the dynamic compression. Much more important.

 

I could be wrong, but I didn't think you could bore a 350 out to a 4.125 piston, thats a 400 piston. I know you are using the 3.75 stroke. Maybe I read something wrong.

I lloked at it the same way. 4.125 isnt the bore its the head gasket size.

 

What DCR should i shoot for.
remember im shooting at least a 150 shot.
im still going w/ the -5cc pistons
but going w/ the afr 220 lt4s and 64cc's

 

from this site
here

is that right??

 

You can get away with 8.5-9.0 on an LTx based motor and 92/93 octane. If you are running 91, shrug, not really sure.

 

Why are you running a 4.125 head gasket with a 4.030 bore? I did that once on my olds 350, used the wrong head gaskets, filled the engine up with water the first time i started it and ruined it.

I gotta be missing something here.
