Carl, you were asking about my BMEP numbers.. I just ran them this morning on the DD2..Because I have Glenn's build on the EA3..

But with 11 to 1 CR, the T-Ram, CompCams 308R, the highest is 199 @ 5000 to 5500 RPM...and then it drops back to 173.2 at Max hp at 6600rpm..

So that tell me its the highest at Max Tq, rpm...

Thanks Russ, thems big numbers for race fuel only for your toy.
You will always have the highest BMEP numbers at
your highest maximum tq be it built for tq at 1,400 or
5,500 rpm's, I know you know that.
Thru different cam grinders in the past and Edelbrock tech
they all recommened the upper limit number of 180 BMEP a
for pump gas street motor.
I'm guessing they are talking 92 octane pump gas or the
highest available.
To go higher numbers you would have to reduce your
thermostat temp or timing which is a self defeating step
backwards, aluminum heads a plus.

Off topic, you caliber those end stands?

 

Yeah Carl , I have started on the Print for those but havent finished yet..I'll try and get them to you this week end!

And yes I'll be running Stage II KC Edheads!!

Well now that BS is over!! Carl I ran those numbers back threw again..this time with a 10 to 1 CR..because I think the Aluminum heads are good for 1 point as rule of thumb..even at that..with a big cam, valves, its still going to be 188 BMEP...So I'll probably have to make up some home made fuel additive!! Nitro? LMAO!!

End and side view dimensions hand drawn would be great Russ, aka stick people drawings, well almost.
Are the center stands like the end supports without the mill slot like original 427 stands?
I was wondering why they didn't slot under the anchor bolts but not the very end support thinking it would support or grip the shaft better.

You know by now i'm a stickler on building by BMEP numbers.

The old 9.1cr 414 w/CJ cam +2 advance and iron C4G heads I come up with 182 BMEP. Carbon buildup must make it higher. With 180 stat it wants medium grade 89 gas just detecting a tick or two detonation 550 to 5,600 rpm's. Warm days 85+ degrees after coming off the freeway it will detonate fairly solid until the heads cool down a bit if I stand on it, after a few minutes back to normal again.
Fast mechanical advance off idle all in by 2,400 with 37 degrees.
Granted this was built as a low rpm tq daily driver, low pertol consumption and long life, heck going on 20 years, 256K.

 

Well Carl thats a tuff question to answer on the center stands...I havent bought them yet..you know us PoBoys..we have to buy 1 piece at a time...But as I remember from Dougs (pumpbuilders) Site they are not sloted as the end stands are...

I think I'll be OK on the CR with the aluminum Heads..IF Polcats running 12 to 1 with Iron heads.. I'am only a couple points higher on the BMEP scale than I should be for 93 Octane..I guess I should go use that E thing you posted..Last time I tried it ..it was down?

Well let me get another cups of coffee in me and I'll start back over on those End stand Deminsions...LOL..
