ENGINE UPDATE
Thru a series of unfortunate events my 5.7 hydroniced and bent #8 rod and cracked the cylinder. Block destroyed needed to be replaced. Decided to build a better blower motor.
Switched from aluminum to cast iron. I purchased a new GM Performance 6.0 block from my local Chevy dealer and took it to the machine shop. Texas Speed supplied the rotating assembly. 4” forged stroker crank, rods rated for 1100hp, 32cc dished Wiiseco pistons for a compression ratio of 8.6 : 1. Due to the previous motors too high compression ratio it lifted a head causing the damage. This time I went with ARP head studs and a much lower cr. Current displacement is 408 ci.

Wow, seems the higher cr made the engine very unhappy. Sorry to hear, that 8-71 pumped it up. I use Wiseco pistons in Harleys, good products. That new cr of 8.6 : 1 should be much better. Better this go-round.
the ARP head studs will be a nice plus.
Yes, the bore is 4.05 and the stroker crank is 4.0.
That is Sweet, & almost square B&S... Iron Block mostly used in trucks, right ? Definitely must stronger. Is that the same Blower Drive Services 8-71 ?
Wish that was going in my Panel.. (drool)..
This time it’s going to be run on an engine stand before going in the car. This thing is so incredibly difficult to work on in the engine bay. Chasing things like vacuum leaks were very hard before. To this end I’m going to build a low-buck stand. And when I say low-buck I really mean it. LS engines require a specific type of return fuel system. I found out that the fuel pump from a late 90’s F150 pickup will work on an Ls. I bought a cheap Chinese eBay pump for $34 and coupled it with an eBay regulator $22 and a Home Depot 5 gal bucket……. Instant Ls fuel system.
