Ported Gt 40 combo, ???s and critiqueing.
Hey guys, new here. Im putting together a 90 GT stock bottom end, stock cam -4 degrees, FULLY PORTED GT-40 Irons, stock valves, milled .040", scorpion 1.7's, Ported Exploder intake, 90mm lightning MAF, bbk equal lengths, offroad H, and 40 series dumped, with 3.73's, and a T5, A/C eliminator, no smog, and Electric Fan.
Should I go with a 70mm or 75mm throttle body???
Heads should probably flow 225cfm or so on the intake. Will post pics in a month or so.
Will have Summit upper and lower control arms, Already has torque box reinforcements welded in, and will be on ET Street Radials on drag lites with skinnies.
What could I expect in good conditions in the 1/8 with a 1.6x 60', powershifting?
Any thing to do different???? or change???
I also plan to spray AT LEAST a 175 shot of ZEX. Would like to spray a 200 shot. Will be adding an Astro T5 and strange axles into the mix too.
