Grey brought us his car to do some testing on our brand new prototype LS7 cnc program. Made 2 pulls, pulled heads off, installed our ported heads. Made 2 more pulls after a finished tune. Car ended up making 581rwhp through the stock intake manifold and throttle body!! That is within 5rwhp of a well known aftermarket casting ls7 headed/Fast102/102 ls7 we did a while back! Call us today to get your heads CNC'd today!

Nice job guys! How much do you cc the combustion chambers?

The data numbers a a little *tainted* as it wasn't tuned prior to advertised "before" numbers. Everyone knows the General leaves HP/Trq on the table with their tunes.

It was tuned prior to installing the heads..... It got tuned when it got the cam installed.

What were the flow numbers on LS7 program?

Dang, so with the addition of some fast pieces this will make 15-20whp more than an aftermarket casting.

REDTAN,
Or add that same FAST intake & TB to the aftermarket heads and gain MORE. lol.

Read the 1st post carefully

Well no because the aftermarket heads are already paired up with a FAST 102/102. The LMR heads are paired with an OEM intake/TB and both are within 5hp of eachother.
