which scat crank

[qiksix]

hi guy's, can anyone help me find out which scat crank this is,
numbers on crank are; 350375543 and 0506086.
i've tried emailing scat but on response.
i get it's a 383 by 350 and 375 stroke, do the other numbers say what material it is etc.

It don't look like the right Part NUmber..the 350375 looks right which would be a 350 main and a 3.75 stroke but the last numbers 543 don't match anything..

Are you sure about the 543 on the end?If it was 541 then you would have a 4130 Crank!

double checked the numbers that's them, the crank itself has lightning holes in all throws only 1-4 holes go right through, flywheel flange is not like the std gm with 2 90* cutouts more roundish looking, and it has a smooth casting texture to it.
just want to make sure it's not cast crank as i 'll be looking at trying to get over 650 hp from this combo.

i did a google searh and it turned out to be a elgin 4340 steel crank w/ 3.75 stroke with drilled lighting holes. Are you sure its a scat?

it's got scat 3.750 stamped in black on it, doesn't mean alot i suppose, anyway what's the elgin 4340 cranks like, would they handle up to 700 hp.

[cepx111]

Generally speaking most 4340 steel cranks are pretty stout some are better than others the difference in quality typical means allot higher price, I would have to say that it should handling 700 horse no problem.
Just make sure you get it checked out throughly by a competent machine shop, and then have it balanced for your piston & rod combo.
