Long story on the heads..Try to make it short and sweet. Heads were first sent off to be worked. Came back with 2.25 intakes and 1.80 exhaust. All I have is 348 at 7 and 219. The numbers were scribbled on a card and that was back in 1994. The shop that did them has closed up now. Anyway......2.25 and 1.80's ended up touching each other at 6700 rpm and boom! Broke exhaust valve head off..hole in cylinder..smashed up head..broken piston and 2 damaged rods... Been a long road to get back.

I'm no engine builder all I can say it appears to be good. Your torque and hp #'s are close to my 528. Good job Wink

Read through my build http://www.429-460.com/t4799-my-build-my-fox-transformationlotsa-pics see page 6 for my dyno numbers and compare if you'd like.

Theirs a whole lot of power in updating your porting and valve job.

And the cam is a little off for today's thinking.

I'm really wanting an A460 setup but wanting to wait until I can get rid of shock towers.Maybe this winter. How would everybody (redo) the heads?? Engine builder is a BBC guy for the most...next will come from Kentucky ??? I believe from what I've seen on here.

1970 mustang with ladders bars. 315 radials, 4:11 rear and 1.80 powerglide. Weight was 3410 with me in it. I have removed back seat,rear package tray. Hoping I removed at least 60 lbs. Last et was 10.33@133. That was not a maxed out run. Any ideas on new et?

Thanks. 20 year old front shocks kept the front end up the whole way down the track. Tried 90/10 and 60/40 and no difference. I am hoping to go ahead and put a mustang2 front end under it and get rid of the shock towers. Hopefully loose some weight there. A spacer and evac pump will pick me up some more.

IMO the must II stuff is more of a street rod deal, the travel is real short.........If your gonna spend the coin get a strut front end set up and be ahead of the game.

I've been debating that. I see some nice kits out there to do it. I also have a guy that can do it from scratch. I'll talk to him after hunting season is over Jan. 5th.
