Ive been looking to do a ford 351W swap into the Z. But no one in the ford community can come to a concensous(sp?) about the stock capability of the block. and Only certain years can hold more power.
My ORIGINAL plan:
351W Stock crank, forged rods, forged pistons, girdle, arp mains, arp rod bolts, arp headbolts, 77 bearings, stock oversized or upgraded heads, custom manifold, single turbo(.80 or larger), 3" all the way back, the $300 intercooler(mentioned here), BOV, Holly 750 blowthrough, Walboro 555, MSD 6al, HVC coil, MSD distibutor, relocated battery, and and and.....
I want a VERY reliable conservitive 500 - 650. They say that the 69 and 71 blocks for ford are rated there, but they dont know, and its a constant battle.
The chevy swap stuff is allready made, and swapping is far more common. Less original but easyer..
WHAT I WANT TO KNOW:
What is the stock rating on the 350 BLOCK(not hp from a stroker) whats the block hold.
Whitch Junkyard cars can I steal from, and witch years have the 4bolt main?
I dont want to spend all the cash, just to have it snap down the center.
NOT going aftermarket block.
