yep... cant be too hard when these guys are doing it..
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 !

Yep, those were some of yours. Awsome heads I forgot about the markings untill you mentioned it. Ill be getting some of your heads when I get my car here from Texas. I sold the other car I had. It had your heads B-303 cam longtube mac headers performer rpm intake 650 double pumper complete off road exhaust. The biggest problem was getting the car to hook. spin through third. Cool though. with 3.73 gears.

Vert 3750 # race weight with me and my junk. Mid 15's before and 13.93 after.( Im not a great driver either I had a 1.98 60ft ) Im still tuning and making changes. That was with Tmoss lower stock upper and a comp cam nx264hr !!
The fact is I pulled off 1.19 sec off my et and gained 9 mph by bolting on those parts. I just added a cobra intake and elec fan and sub connectors.I need a new clutch and Ill be running it again this spring.

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...

You were right, the B cam, advanced 2 degrees on 1.7 RR's was the way to go. 1st of all the idol is mean, sounds much meaner than even bigger cams. I'm kind of getting sick of people always asking me "what's in that thing". 2nd of all low end tq is also good. Mine is a daily driver, can't afford too much bottom end loss. True, it's choppy under 1800rpm, but once after 2500rpm it's alive. I can do 2nd gear starts even on slight inclines w/o having to revv the engine more than normal. 3rd of all, top end, wow. Goes from 75 to 115 faster than most cars can go from 0 to 40.

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 )

Ex-Nebraska State Patrol car, "Thumper Performance" ported stock heads, B-303 cam, TFS Street heat intake,TNT Force 2 Wet nitrous kit, 3.55 gears, exhaust and all the usual bolt-ons.
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.
_______________________________________
Anyway I run a C4 2800 stall (a lowly 3.08 7.5 trac-loc from an '82 GT-cool factory slapper bars that work effectively), Stealth intake, B303 advanced 2 degrees, 1.7 roller rockers, 1 5/8 shorties. X pipe, and Hooker Aerochambers, and of course your heads.
Every gearhead that I run with (2.3 Turbo guy, 5.0 guy, big block Fairmont guy, '03 Cobra guy, and even my Chevy mechanic friend) all were impressed with this little ole' 5.0's all business like powerband.
Although I have not dynoed or dragged it, I have raced and beaten a Porsche Carrera 2 (drag not top speed...) and played with superbikes on clear I-States very effectively up to my self imposed top speed of 121 mph (5250 rpm @ 23.9" tire).
Nothing earth shatering but hey for what I have in this car- its tough to beat these humble efficient/light weight Fox body Fords and roller HO's with THUMPER E7 PORTED HEADS!
Just a few using my Ported Heads and having FUN doing it!!
