A.P.D. Ports an "E7TE" EFI Head ... Empty A.P.D. Ports an "E7TE" EFI Head ...

... ok guys, i've been spending some time getting to know the BBF iron stuff, and i've done another BBF iron casting, and i'm happy to say, this head has a much better exhaust port !!! ...

... the intake port in the "E7TE" EFI head is much smaller is size, and i dont have the material needed to fit my (2.250) valve sized port in this head, but, a 2.150 valve seems to fit very nicely, the issue i ran into is there is not quite enough material to make the short-turn achieve the shape that i need, but its close, IMO this head will make for a serious street/strip head, especially for the pump gas crowd, the D/C and CFM/Sq.In. of valve are good, and so is the FPS ...
... the port map looks good, as well as the avg. cfm, so here are some pics and the flow data, the nice thing about this head other than the nice exhaust port, is the lack of a heat-crossover, so no filling needed there ... but i am at .100 -.120 wall thickness everywhere, so i cant touch the port anymore, other than to add a wing maybe ...
... now these numbers are without any chamber work, on a 4.375 bore, so maybe there is a bit more left in it ... we shall see ...

... it's sweet and sour with this one really, as the 2.150 valve helps to unshroud the "over-bore-center" problem the 460 heads have, but if i had more material, i know i could get this port to flow 400cfm, and that's with a 2.150 valve ... Suspect

The best part about this is that a CNC shop is willing to cut cast iron ... SOoooo many won't.

I would cut cast iron if I could get a substantial run. Two or three sets wouldn't worth the effort.

Guess what ... ?
Most customers don't have more than one set they need to be ported because they only have ONE engine so, your mindset is exactly what I was referring to.
