But i also think most ppl. like myself aren't going to get a stock headed stock cammed mustang that fast.
Hey Tom,,do you know anything about the street heat intake? I hear its good for low end.Would an Explorer lower bolt up to a stock upper?(Mustang upper)tmoss said:Whatever intake you use, be sure to mock up the lower intake with the AFR heads and see if porting will be beneficial. In most cases it is. A customer of mine recently switched from a ported Explorer to an RPMII and lost torque and HP across the board, then switched back to the Explorer. The 165 heads really seem to respond well to a mid-size runner cross section.
NYC LSC said:I have the Thumper heads (stock valve sizes and heavy duty springs) with a Comp Cams XE270HR-14 cam and it's gotten this 3800+ pound pig down the track pretty quick for what it is.
When I first took the car to the track and it ran slower than the old motor's times, I was convinced I needed better heads and would tell all the guys that I think I'm gonna go get some AFR 165s.
As the car sits now, it's 1 second and 9mph quicker than the old motor. I gotta believe that the weight difference between my car and a Mustang would put a Stang in the high 12's with this set-up.
Good luck with the new build, man. Maybe I'll catch ya at E-Town next season.
I already have a ported lower from him,,do you think Im better off with that? How about an explorer? I love the bottom end torque I have rite now,,but would love to have morersw007 said:willy save the money on trickflow or elde. and my ppi and have tmoss clean the ports for about the same money. i think it would be better than the other two out of the box.i i would go the thumper route and save the money for suspension and dyno tuning.
Would an Explorer be ok? Or should I go with a Cobra?rsw007 said:the thumpers will flow more than the stock ported lower will flow so i suggest a better intake. the low end wont suffer much with your converter.
forgive my ignorance,,,ppi?///what about those turbo swirl gt-40's??rsw007 said:you can find a ppi intake on ebay for less than 300 shipped usually. have it shipped to tmoss spend another 100 or so, and it will flow big numbers.

5spd GT said:Yeah but at the track you only use that "off the line" power for literally probably a second...and the rest of the trip down the rest of the track is at 3500rpm+ where the AFR's really start to shine...they keep wanting to rev...
And usually when you look at dynos of AFR/custom cam setups they have similar torque numbers down low but because of the greater hp in the upper rpms and gives the ole' SOTP fake and makes you think you lost torque...that is how I look at it on my car...because I have the same if not more torque (going by feel) than stock cam'ed and of course the upper rpm doesn't have much of a match...

jocko said:HELLPPP,how do i get a hold of the thumper heads?do they have a website or phone#?...
jocko said:hey 89tang,how did you bend the valves?and for everyone else sorry cause i never heard of them but who sells the thumper factory castings and are they better than the gt40's turbo swirl 194/154 valves that they advertise in the mags for $699?
