i brought 4340 cat crank with a 4.250" stroke, i brought it off ebay for 600 bucks.
i thought it was a scat crank but now the box just says cat, is these two different companies? or is it the same? our both cranks reliable? i just want to know if i got riped off, and if i did, buy how much.?

 

never heard of cat lol look on the crank is the a # or anything on it? and as far as reliability id say scat is desent not #1 but i dont think your goin to be shooting 500hp of nitrous through it so ul be ok
