Re: AFR BBF Head

I'm looking at the crank and it clearly shows the approximate 3/4 inch larger diameter that I posted about that the Danny Bee belt drive lower pulley won't fit on. So if anyone is considering a Danny Bee belt drive system be aware of this problem. Mine is a scat crank but the stock crank was the same as the one in this picture.

The AFR heads are a quality product, and they are better 'out of the box' than a P-51 or SCJ head, yes?
But with some porting, the P-51 and SCJ's would make more power than the AFR's, yes?
But with further porting on the AFR's, they would out perform the P-51 and SCJ's, yes?

Has anyone done any custom porting on a set of AFR's yet??....I mean like somewhat beyond the out of the box CNC job that they already have??
If so, it would be interesting to see the comparison of the CNC version against a hand ported version.

As I understand it, a set of P-51 or SCJ heads still needs the intake to be ported/matched to the heads (if one wants to optimize their combo), but the AFR intake matches the AFR heads a lot better right out of the box, yes?

YES, HAD A SET OF THESE HEADS in my hand today, I hope I get to work on a set.keep in mined THEY come ported from AFR.

A work of art and functional as well. How does the oil pickup tube get supported?

Lem Evans February 25th 2018, 11:48 am

The usual main bolt with the 3/8" stud on the end.

That pan looks really nice! Not trying to hijack, but what's the best way to put one of those on with no outer pan rail visible and only the holes, I never had one before like this.

And very nice build Lem, you and Flip both know how to build one hell of a motor! Very good showing by the AFR heads also!

Nuts on short studs, VERY carefully, from the bottom with the engine upright.

The pan came in today and it looks as good as the pictures. I was expecting some stickers but I can wait. Someday I'll be in the 8's and make you proud.
Thanks much....

Lem / Philip,

What adjusting nuts did you guys use for the AFR / Jomar stud girdle on this build? The AFR information online is horrible for these and half of their links are broken!

Thanks,
Butch

The bars came from AFR but, the adj. nuts were not included......the 2.200" Jomar units we had in stock at BF Evans Ford were used. Worked great. We'd be glad to help you with any part of your AFR needs.

I'll take a stab in the dark and say it's a trick question and there was no vacuum pump.

15" Hg and still had ~75 psi.

Just noticed the massive hole in the front of this block do you guys put that there for oil drain back? I have seen them drilled in the front but they were only maybe 1/2"?

It's just a matter of how big of a hole saw you pick up. Smile
