Blown stroker 478

[Cuttyman9]

It started with the purchase of a 305 gmc v6.

It's evolved into a couple 478 v6's and an 8v92.
The truck is a 66 3/4 2wd Chevy, I'm using an eaton ho72 and a Dana 60 front(when I find one) for the front axle.


I have a number of things I'm still trying to track down for the truck still but the process is on the way.

Info I've found so far is the crank is giant, and swings around heavy rods and pistons.... but the journals are also giant so I can cut them from 2.8" to 2.0" and bump the stroke 1.6" and since the pistons have such an insane compression height I can keep a long rod and not compromise anything so long as the crank and rods fit and can swing it without hitting things it should come out to around 5.155(0.030 overbore) and 5.18" stroke for a 600+ cubic inch v6.

I have the steel bits to make the blower manifold and an adapter to make an 8v71(or in my case 8v92 which is the same blower) fit where an 8-71 would be.
