My bone stock 5.0, just has a cheap air intake, exhuast, and gears, and DRs. Goes 12.9@108 with a 1.7 60ft. The first car seems alittle slow for the mods done to it, Might want to redo the h/c/i setup on it. That cam is way to huge for a E7 headed car i think.
the heads had some small work done to them. gasket match, bowl work, double valvesprings, etc. read the original post. it has trick flow cam and cobra intake
I did a 12.3 @ 111 with a 150 shot on an NX wet kit. it had a stock block with an e-cam, stock aod ,stock converter with transgo shift kit with stock 3.27 gears. sprayed it tons of times on the street and loved the spray. as long as u keep good plugs and right timing should have no problems.
My car has stock heads, stock intake, TB, i dont know about the cam, it idles alittle rougher then stock, might be a E cam or something like that, i didnt put it in there. I pulled the motor out of my 90 Vert and put it in my car. I run one of those ZEX dry kits that ups the fuel pressure, seems to work pretty good. Plugs stay light brown in color, run 24s, and 14degree's of timing. 108mph doesnt seem to bad, wish it was that fast on motor.
