4 bolt vs. 2 bolt
#23
Yeah... the consensous of most real SBF builders is "dont waste your money on a main girdle". Not gonna stop your block from splitting.
I think the 2-bolt and 4-bolt main question was answered pretty good. With these engines, you might as well giveup on the 4-bolt main idea unless you plan on buying an aftermarket block, but i think i read the word "cheap" somewhere in your original post so not happening. In fact, if youre looking to get out "cheap" with a 347, i think youre gonna get in a little too deep. **** adds up quick... especially if you wanna make any kind of decent power.

I never said it would stop a block from splitting i was just implying that (my opinion) a girdle would strengthen the bottom end by tying the bottom end together reducing the deflection in the main cap assembly

that can be solved with a good set of ARP main studs. about the only thing a main brace will do is keeo the motor "together" when it actually splits in half. while there are ways around the weak 302 mains like getting a mexican block or an older 302 block. if you want to build a big hp 302 you need to go with an aftermarket block, DART, BOSS, etc. or you could just get a 351W and stroke it out to a 408 for some good torque. the 351C is an AWESOME block, but its very hard to find a suitable block because they're prone to developing cracks. however, if you DO find one a 351C can be safely punched out .060 over unlike a 302/351W which is borderline at .040.
other than that, parts to fit one in a mustang are sort of hard to find and there are practically no options for EFI. carb, go hog wild. exhaust fitment is a b1tch too with a 351C.
