Need a FAST 90 ported....

un-needed for a stock cube ls1. even with h/c/n

runner length and volume is optimum for airflow and velocity untouched.
 
porting?

porting a fast 90. i hope you have forced induction or you are going to lose power. if you use a fast 90/90 which is throttle body and intake, stock it can handle a ms4 :naughty1:, bolt ons, and nitrous, no problem
 
Do it yourself. Lay it up on a cylinder head and mark it. I hear one of the corners is blocked pretty bad from the factory, which is where you get most of the gains. There was a pick on ls1tech a while back of it.

Found that write up thanx!
 
i don't see why people port these. look at the port match. 99percent of the time unless someone has gone crazy with the grinder the intake port on the head is smaller than the intake manifold which creates a big ass wall for the air to run into. so as far as i see it need to get out the grindin bits and match the port on the head to the intake. then if ur ganna go that route i guess u could port the intake then match the head to the ported intake.
