the lower intake runners are the biggest restriction ive read. i tried to find the tmoss porting website but its no longer around, hes part of this forum you could PM him for more info, he will tell you whats what on the stock intake
I am looking to setup some mods in the next couple of years. I have an 87 Speed density with 5 speed, 3.73, diff rebuild with kevlar clutches, flowmaster 2.5 catback, Pro 5.0 shifter, 2 row alum radiator, K&N, free power mods. I plan on adding some headers and an X-pipe first and eventually want to be low 12's car with no nitrous or slicks in a few years, maybe drag radials. I am looking at AFR 185's, intake tbd, maybe cam, fuel pump & injectors after exhaust and intake.
I think I may go with the twisted wedge heads instead of the AFR's since I don't want to get into fly-cutting pistons or changing them like mpe331lx noted. Will this combo most likely get me to my goal? What does mpe331lx mean when he says ported twisted wedge heads may be "too large for my intended combination"? Any other suggestions? Thanks
im sure your right....but basically you can replace either or in this case but if you just replace one of them its not gonna get you very farintake is most restrictive, then the heads..........
