With a blower in mind and using a 292 block, then the 292 steel truck cranks (C1TE) merit consideration simply for the increase in snout strength.

Dan: First is the 312 a 56 or 57 block? If a 56, a close check of the main bearing areas is in order. Unfortunately due to a spec mistake, in early in 56 production, some blocks were cracked or main bolts in some cases were stripped due to a torque spec that was to high. Or in some cases due to overzealous torque used during a rebuild. One of the reasons 312 blocks are in short supply. If the crank is really good & not turned more than 0.20, J.Mummert charges a core at $400.

It's my opinion that if you are going blown that the 292 block with a set of ARP studs is the way to go. Might even consider a stronger set of rods.

Try to sell the 312 block on eBay, I hear they'er going for a $1000.

Fellas,

I found a 312 block with the crank and the rods all together.

I have cut down a 312 crank before to 292 main size, but is there any really good reason to use the 312 block, throwing all the internals back in, or should I just go with a C2AE block I have laying around (provided its good, of course)?

I am looking more for performance with this particular engine this time. And would be considering a blower set up for the future.
