Hi Dave,
Finally got my turn on the dyno to run my 377 cleveland.
The final figures are 593.6hp at 7036rpm and 505.8 ft lbs at 5353rpm.
Premium unleaded 34 deg timing.
It made more tq with 850 mighty demon 511ft but less hp think it was 560-570hp its my mates carby any way so
didnt want to get to excited.
I guess now my mate Shane will be giving you a call.
His XA falcon just went 11.7@115mph 2v f-246cam.pump fuel
Will send you a dyno copy when I get a chance.
Thanks for all your help keep up the good work.

David,
How are you going?
My name is Brett Murphy, from Western Australia.
I have AFD 2v heads on a 378 clevo in a 71 ford capri street car. I recently upgraded my crane F238 to a AFD 2522M cam. With a converter to suite my time at the drags went from a 11.32 @ 119mph to a 10.9 @ 121mph.
This was on pump fuel through the exhaust. The exhaust is quiet and very restrictive (twin 2 1/4 into single 2 1/2). I now have to fit a roll cage and comply to super sedan standards.
I plan to drop the exhaust next time I race, and hopefuly replace my inlet manifold which is still a holley street dominator. As I have been more than happy with your heads and cam I am hoping your inlet manifolds will soon be ready.
I am currently making around the 400rwhp mark
Sorry for the long message, just wanted to let you know how well your products are doing even on engines with poor inlet and exhaust systems!

Regards

Brett Murphy

David,
I just wanted to take a moment to thank you for the heads I purchased. You worked with me one on one to insure I had the right set
up for my motor.
I've got my motor together and it runs way above my expectations!
I'm running well over 600hp with the 2v Cleveland heads on my 393
Stroker and I've got power brakes without a vacuum pump!
I can't wait to surprise the Chevy boys this spring at the track!
Here is my set up for my 68 Cougar.
AFD 2v Heads
Edelbrock Air Gap Manifold
Mighty Demon 830 carb
Howard Camshafts - Solid Roller Cam/Lifters/Rockers/Girdle
MSD Ignition
4bbl headers
Ford AOD transmission (Modified with AOD Lockout and Stall converter)
4:54 True track

Anyway keep up the good work and I'll keep promoting your heads!

Thanks,

Dear AFD,

Through Glenn Everitt and Matt Jackson @ G & D PERFORMANCE , you were recommended to me for your headwork ( I also had read a write up in Street Machine,.....Bob Kotmel’s page ).

I am just writing to say how stoked I am with your work,..last weekend I took out the trophy for my bracket “ Super Street Slicks” at the LS1 street machine 2005 Drag Nationals ! These heads flow great, “ get it in , get it out !!! “ my thanks again,
regards
David McWaters

David,
Mate, happy as hell with the heads, mate they are a credit to you. You should be getting heaps of orders cause the interest they receive at the track is amazing.
The old girl run 11.5 at 118mph on its shake down pass off the trailer. We started to experiment with tyre pressures and had a loss/gain session.
The xe weighs 3700pds without me so by the calculator it is making 500 moroso hp with no tuning.
Next time out I will play with jetting to see if I can pick up something. what intake manifold do you recommend?
the Active seems ok but do you think anything is better.
Hopeing to crack 10's with the heavy full weight street car.
Got a few toranas up here that need to be tought a lesson.

Thanks Luke
