compression
 

what is the compression ration for a stock 1990 454 fuel injected

About 7.6-8 to 1 ,not much

i want to up the compression just for a stree rod its in a ss truck what can i do

well if ur lookin to rabuild just have some head work done and get some flattop pistons
but i fnot u could just buy some new heads with a smaller combustion chamber
and if u dont want to spend that money u could even cheap out and just take the heads and have a valve job done and have them mill the heads down a few ccs

i was thinking of buying new heads and cam but don't know what to go with

dart iron eagles are the best for the money
but world makes a good head too and they're a lil cheaper
and cam wise i say a comp or voodoo prolly around a 520 lift

thanks that should wake it up some. still trying to figure how much horse power it came with from factory

i figure it prolly came with about 400 give or take a few

thats what i figured to but the heads they put on it suck got to wake it up and let it breath if u know what i mean

does it have headers, true duals, intake, etc.
