Using Edelbrock Victor Jr heads...I ordered them bare and assembled them with the seals, springs, retainers, locks, etc. to match my cam....I've seen assembled aluminum Vic Jr's without any spring cups...so that definitely signalled me to put them together myself.

I'm using a 4.060" 1979 block...an Eagle ESP 4340 4.100" crank, Eagle 6.200" H-Beam rods, and Probe 10.5:1 pistons. It comes out to like 425ci I think. Dyno'd at 484 hp, 500 lb-ft with a 750cfm Demon (too small a carb....should have used an 850) and a Vic Jr. intake manifold. Power peaked at 5400 rpm, and torque peaked at 4500.

No problems with the block...used ARP studs everywhere I possibly could...and of course used the main cap girdle.

You'll find that there's quite a bit of users on here with 400-600 hp Windsor engines...393's, 408's, 418's, 427's, etc...probably most of them on stock blocks
