I have a 396, Fully machined never reasembled after machine work. It was bored 30 over, and have TRW 11.5 to 1 pistons in the box with the rods hung. Crank refinished, Stock heads in good shape but not rebuilt. stock intake manifold, harmonic balancer etc. Ran the specs on my desktop dyno and came up with 545 Hp with minor perfomance parts. I was originally going to put this motor in my 68 Chevelle SS, But have decided to go all out on a 502. Question: What do you think a motor like this would be worth? If the price is right I will probably sell it or keep it for a spare for the blazer. Thank you.
