12s on just a little....
Here are a few guys running 12s on Iron E7 heads...
I wanted to tell you a buddy of mine bought a used set of your heads and put them on his stock bottom end car with a cobra intake and ecam and the basic bolt ons He busted off a 12.24 @ 112 mph on a 100 shot of nitrous he had a 1.81 60 ft Pretty good huh!! Cool HUH!!
__________
I run the ported E7's also and love them. It was a lot cheaper than buying expensive aluminum heads. My best ET before the heads,cam, and intake was a 13.6 at 108. Now day's it has so far been as fast as 12.24 at 113 and there is still more in it to go once I drive it harder at the
strip. Still getting used to launching the new combo at the strip. Oh yeah that was with STOCK headers cause my Mac's were cracked in three places and had to junk them. _________________
The first pass of the day was a 12.58 @ 108 mph, the car seemed to boog a little out of the hole. The second and last pass was a 12.45 @ 108.4 on a 1.73 60 ft!! the heads and cam were unreal!! I droped almost a full second from before with the head change!! We are going out tonite and see what we can scare up....

The car is my full weight (nothing removed except the front sway bar) daily driver with the a/c still on it. With no changes other than a set of 26x8 MT ET Drags, the car went 11.65 @ 115.8mph on the 175 shot (any other 60' time from the night would have given me an 11.5x) and 11.87 @ 115.8mph on the 150 shot. .
Overall, I'm pretty happy with 11s in my daily driven bolt-on car with Ported Thumper Heads !
____________________
I run Thumper Stg2s and a Tmoss Ported Explorer...They work..plain and simple...its cheap money and i like that..plus i like running Ford parts...i could have gone the other way, no problem...I just like the idea of banging 12s on ported stock parts...
The way i see it...i got a mild cam, the heads, and decent breathing mods...i got almost 300FWHP...not to shabby far as im concerned...thats about adding 80 HP over stock...thats a nice, noticable hit...

"unique" combo in and dyno'd
Well, it's a unique combo because my plan has had to change a few times due to things breaking. It's everything off of my old 302 swapped onto a shortblock.
The main parts of the setup are:
D.S.S. 331 stroker shortblock
"thumper" ported E-7 heads
Edelbrock performer RPM intake
Steeda #19 cam
24# injectors
190lph fuel pump
unequal length shorties
off-road H pipe
Flowmaster cat-back
dyno-tuned superchip from La'Roccas
The combo made 296.8 rwhp and 344 rwtq *******
( over 348 FWHP w/15% power train loss )

12.80@106mph--motor
11.88@119mph--w/100 shot
** NEW COMBO **
347 Stroker, Thumper Heads, Keith Kraft custom grind cam, Vic. Jr. Intake with BG 750 speed demon, 2 speed PG with TCI group 6 stall, 3.73s.
11.83 N/A 115 mph

I run 12.80 @ 106 with 1.77 60fts on drag radials. My local track is @ 3000 feet in the desert. Corrected for elevation, I'm some where in the 12.30's. My car is less than 3000lbs and has an electric fan, manual steering, K Member....4.10's and even more suspension junk. I run Thumpers with an e cam, 65 mm tb, 73mm mass air, and cobra intake. I think that with more tuning and a real slick I can drop another tenth or two. Simple combo, light weight, and matched parts all make for a pretty stout street car. I can drive anywhere as long as its not hot- no ac.

Mike, Just a note to let you know what we did at the track today! The place was crowded bad as it was the first day of the season. The first pass of the day was a 12.58 @ 108 mph, the car seemed to boog a little out of the hole. The second and last pass was a 12.45 @ 108.4 on a 1.73 60 ft!! the heads and cam were unreal!! I droped almost a full second from before with the head change!! We are going out tonite and see what we can scare up.... see ya at Hooters around 1030. Thanks again for the help and word on the cam advance.
