ported GT40P flow numbers, and pictures
 

The stock flow numbers were taken from http://www.pinn.net/~nascar/fordhead.htm

I would guess that the small differences in the low-lift flow could be accounted for in small testing changes between the two environment and flow benches.

heres a few shots of the heads:
this is a shot of a felpro 1415 exhaust gasket on the heads.

thanks again Tim:cool:

Who did your port work?

Caymon

Hah, that web-page is a Va local boy :) I recognized the dragstrips!

The top one is the now defunct Suffolk track (like der with the sign)

the bottom is Dinwidee. The track where they hold Fun ford Weekend in Va.

302man- Tim of Donathen & Son motorsports did the porting
:cool:
I was going to be heavily involved in the porting, but I went to vegas while my heads were at his house, and when I came back, they were done!

He helped me out alot on the porting of the E7's that I ran 12.80's with, and he's getting better with every set of heads he ports, so these things should work well.

Hey, I have heard of DSM . (Donathen and Son Motorsport) I think they were in last months MMFF ?? LMAO

There sure is a huge difference between here and the corral. Everybody and their brother seems to be looking at the post over there !

Very nice work I don't know on the GT-40P's but has he tried anyone tried a "D" exhaust port on them yet?

Did he do anything to the chambers or was all the flow gained from just the bowls and ports?

All bowl and ports. fiveoh didn't want to loose any compression, so we left the chambers stock with a .030 cut. I cc'd them, they are about 54cc 's I think. I am sure 5oh will correct me if I am wrong.

55.5-56cc on the one we checked

How much money was it, If you dont mind me asking.

No money exchanged. But he owes me for life ! :p

Tim, I've owed you for life for about 3 years worth of help you've given me:D, let alone all this

I'll pay you back by being the full time driver for your car this year :cool:

Thats graditude for ya !;)

Have a look at this

CNC ported P heads that on average flow about the same as these. Damn your good Tim!

Ya know, I coulda swore I got an email from a Tim Donathen a few days ago, lol. Small world... ;)

Very nice port work! :)

Later,

Ya, small worlds are kinda nice sometimes !!!!

Those are some pretty good numbers. That should drop those times down a bit ;)

Hey tim, did you happen to get any pics of the bowl work?

I have pictures of everything... but its a secret !
