Definitely not enough that its worth the money to do it all. Going 80 to 85 just isn't much at all.

Maybe 10-15 hp.

Get a set of L92 ported heads for $1500 and make 40-50 more.

Agreed with BlkBird, Buy a fast 92/92.

at the moment is has a ported wiend ls6 intake ported 5.3 heads similar to texas speeds version and 1 3/4 hooker headers. One thing that does not interest me at all is the fast I have been rading to many bad reviews to pay 700+ for a piece of plastic wich may or may not have as high of quality as it should.

i'd say 10hp or so by not going bigger on the lid/maf

but you'd need a new tune after the maf.

you could gain some with the FAST...but again not a ton.

going from stock ls6 intake, and ported stock TB....to a home ported FAST 90/90....i gained 18rwhp and 12ftlbs of torque peak, and 5-12 hp and torque from 3000rpm and up.

it was worth it for me.

the FAST is a quality piece....
