Well I finally found out that the engine I pulled out of the 71 Nova was trash. The machine shop is looking at around $ 3500.00 to rebuild it. I have seen some pretty interesting offers on E Bay from a couple of machine shops that offer 350's and 383's with 375 plus horsepower at reasonable prices. I was just wondering if anyone has purchased or know of purchases of this type. I am to say at the least , skepticle of E Bay , after the problems I have had with the Nova I purchased. The two main machine shops have glowing reviews by buyers. These engines seem to have everything replaced. My machine shop is using my pistons, rods and crank.
