OT-hp estimation
 

just planning to build a 454
11:1 cr
around 600 lift mech cam
oval port heads (99%)
tunnelram with twin 400'

do you think can generate smthng like 450?

it should make that with only six cyl. firing!!!!:D

:) lol sonic;
but these gm oval ports are reaily bad heads.i dont have flow bench and etc.so the head work i do is very amatuer stuff.
will put this on a car and dont want to spend $ 's for heads etc..will just use whatever i find.....
