371 build W/Big Mouth heads

[yellow rose]

Had some very cool lifters from Topline Automotive come in. .012" EDM, USA steel, and weigh 100g's. You can see who makes them on the boxes.
Also including a shot of the intake. I have everything ready to go BUT the block. J.Rob

Is that the cam you were going to use in EM that you posted specs on a while ago?

Found my first flow test of the BM's OOTB with no "help". The labelling is backwards and I'm not the best at online charts this early in the morning. J.Rob

decent 'ported factory iron head' numbers, till .400, then its like factory ported numbers again....lol ....
If you don't lift the valve .680-.700 .....these aren't the heads for you....these heads are over priced factory aluminum.
The exhaust port ...now that shows you they're just going for max and no balance...wtf.
New guess, 532 hp
Disappointed.

Heck yea! A 371 is just a little larger than most .030-360 engines. (365 cid)
Similar results could be obtained at home.

I managed to get a lot done on it this week (sarcasm). I was able to get a coat of paint on the block and that's about it. J.Rob

I wish! Swamped right now and have to cut my lawn about twice a week. "Soon" though, soon. J.Rob

RAMM, what is your opinion on these big mouth heads if you were to port them from scratch instead of Hughes?
With the relocated pushrods, Is the cross section enlarged enough to gain flow over standard location?
