I'll do it for you dlowe.....that's a really long rod you're using...does that thing like to rev?

I'm using a 4.100 stroke and a 6.200 rod....it makes every bit of its power at 5400.....

Anyway, give me a few minutes...

Oh....one more thing....need to know if you have a single or dual plane intake....if you don't respond here in the next few, I'll just do it with both.

OK....

The cam grind I came up with was a hydraulic flat tappet, 35-250-4, 240 and 246 degrees duration, .541", .544" lift, 110 degree lobe separation.

With a single plane and a 650cfm carb, 434hp @ 6000, 431lb-ft at 4500.

With a single plane and a 750cfm carb, 442hp @ 6000, 434lb-ft at 4500.

With a dual plane and a 650cfm carb, 403hp @ 5500, 417lb-ft at 4500.

With a dual plane and a 750cfm carb, 409hp @ 5500, 421lb-ft at 4500.

Desktop Dyno is pretty good on being right with the horsepower numbers....sometimes the torque is off a little though. When I did my engine, I came up with 490hp...it dyno'd at 484.
