Thumper Heads vs Trickflow/AFR

[tmoss]

For those that do not read carefully, those ported E7's were not Thumpers....

Right, they were done locally by a shop in Canada.

When I read "Thumper" heads I always think of ported E7s and how they are not supposed to be worth porting. That was my point - those were ported stockers and they ran the number.

agree'd.

i think i going with the trick flow package and a 100 shot of nitrous

Forget the power gains from aftermarkets, just look at the weight loss and that alone is a good 1/10th just from having better traction under launch and less weight down the line.

As for power, I went with AFR just because they are the sh1t...

I ran 113mph with FTI E7's and stock cam last year in NMRA Factory Stock on BFG drag radials. And now I have a junk yard motor in the car with GT40's and an AOD and my best mph has been 108 and change on drag radials.
I'm sure Thumper heads could do the same thing if not better on my car. The chassis works great.

Another big believer in ported E7TE’s. I took home top honors at the local strip last year and ran 8.9’s at nearly 85 mph in 1/8 on Dunlop SP street tires with ported stock heads, ported lower intake and stock cam with 1.7RR, pulleys, electric fan conversion, 3.55 gears and full exhaust in my full weight, fully loaded ’87 5-speed LX. For comparison, all other 5.0L’s and 4.6L’s in the Street Class were running high between 77-81mph that day. A lot of whom were running various high dollar aluminum heads/intake combos.

I even managed to edge out another guy with the exact same year car who was running 3.73’s and all the other identical bolt-ons with untouched heads and intake, but a 125hp shot of nitrous to even things out........needless to say, when I popped my hood to reveal stock heads, intake and no nitrous, he was pissed.
