Edelbrock Pro Port 440cfm heads, KRE MR1A block, intake build
 

local circle track motor
Edelbrock head casting 7781

exhaust port, KRE ? intake manifold

Impressive looking heads! What cubic inch and what intake?

I believe it's a KRE intake, 540" motor

Nice!

Are those the heads that Butler and BES advertise on there web site.

Circle track ?
He will not have any problems with torque out of the corners !

I think this is a pair of heads Butler had in stock for quite some time, were on Ebay once, and he bought them, had them CNC ported. I may be wrong. but I saw identical heads on ebay a few years ago. yes that would be them I'd assume. pro ports have a raised port, and a solid rocker stud boss down the middle. and the bottom of the intake port face is scalloped back.

Looks like a BOP intake to me

That gona be a bad a$$ one for sure.

GT

it may be

forget the "want" list lol this is a "NEED" item lol
i can just hear the air being sucked in by the carb and the sound of a solid lifter cam thumping out the exhaust........ talk about therapeutic therapy :)
sweet looking setup for sure...... keep us posted on this build :)

What circle track class allows 540 cid?

I'm wondering the same?

I believe there are some big block classes around the country
