Wow! Awesome build

That should slay quite a few Chevy's!!

Damn,.....

9000+ RPM,....
That's NUTS

Is the displacement dictated by rules/weight breaks? Where will the car be running?

That's a beast of a motor! congrats

No, class rules did not dictate the cubic inch. I had the heads, some used pistons, and a crankshaft. I need an engine until my 640" billet headed deal is done.

My home tracks are Mid-Michigan Motorplex and US131 MSP. But I will be running some OSCA races and Milan Outlaw 632 with this. And whatever else I can find that it fits in, including some fast brackets.

Cool deal

Nice!!

That is one awesome engine!!!

Don Losito heads?

Hell no lol. My billets. Visner Engine Development.

Those are the ones. I've made a few changes to them over the years, but same basic design. The new engine will be 640", valve sizes in the head are 2.650" x 1.850" will have just over 1.100" lift. Looking to make 1500-1550hp with it.

I'm actually going to be putting this 560" deal back on the dyno here in a few weeks. A few minor changes to it, id like to be closer to the 1300hp mark with it. I think I can get close, but not sure if I can cross that mark without a piston change.

What bore and stroke on the 640"?

4.705 bore and 4.600 stroke

That's a big piston! What block are you going to use? 4.9" BS?

Eliminator Premier block. Yep, 4.9 BS

That's awesome, I thought you might build it on an aluminum block.

Could you put that head on a 4.650" bore with those valve sizes?

Yes, it will fit on as small as 4.625" any smaller than that, the intake valve needs to go down to 2.600"

Can I borrow this motor to get my Torino into the low 9's just once??

Better yet, for $30,000 you can keep it!

Changed rocker arms, springs, and cam timing. Now I'm fairly certain the carbs are too small.
