would stock computer work?
 

i posted this in tech/ gen engine, but i think it goes here-

my combo is lt1 intake, ported zz4 heads (l98 heads with lt4 springs) solid roller cam Advertised Duration IN/EX: 282/290 Duration @.050 IN/EX: 224/232 Gross Valve Lift IN/EX: .502"/.502" Lobe Sep Angle / Intake Ctr Line: 112/108
compresstion about 10.5:1 363 cu in . i am wondering if the stock computer will work good enough for me to get it started without any issues and if it will work how much tunning would it need?

if anyone has a similar combo id appreciate any feedback. im trying to decide if i should buy stuff to burn my own chips or just buy an aftermarket pcm

I think it will start and run, but not good..

It will need some serious tuning but the stock ECM can handle it, just go for DIY-PROM. If you have alot of money and if you have no exp with tuning GM ECM it would be easier/quicker to get a $$$ aftermarket system......

GM ECM can control my engine without any problems after some tuning:D

/N.

yea, that is what i think. i have seen the holley comander 950 retrofit controller list for 950 at summit. i think that is the way im gonna go. my next motor is gonna probably be wilder, and i may be ahead to just go ahead and start out with an aftermarket system.
