340 Vs 360

Combine the two...

Get a 340 block that will go .030 to 4.07, or even .040 to 4.08

Find a 360 crank CORE, (probably free if you look) and since it will have to be turned anyway...turn the mains down to fit the 340 block.

Shelf (hyper = cheap) pistons are available and with a light SCAT rod, you'd have 372+ tire shredding cubic inches inches! HUGE bang for the buck, it you ask me.

Seems like I see a few reasonably priced 340 cores her in CA every week...
