Re: Rebuild or Crate
I had a similar dilema. I had Z/28 with only 30,000 original miles with the oringinal engine. It had been hopped up with a huge cam and lifters. I purchased the original style cam and lifters and had them put in but it never really ran that good and was prone to running very hot. Since it was the oringinal engine I needed to keep it, and keep it stock as possible. A friend had a 68 350 that was not running too well and I picked it up for 275 complete. It had a 4 bolt main and it turned out it was just a broken valve spring. I had it dismantled and rebuilt with a mild hydraulic cam and since mine had all the original hardware and smog pumps I had them all put back on including the winters forge manifold and DZcarb. I put the other one in a shrink wrap for the next owner and I really only put about 1000 miles on the new motor. In the end it cost me close to 3000 Can. becaue I needed a different starter and I had the clutch and pressure plate replaced. I kept all the old parts. I guess what I am saying is if you can't get a motor worth rebuilding go with the 350 crate. I had thought about it but I had heard,(and didn't verify) that some of the older parts will not fit the new motors. You will have to clarify that. One thing I did get with the rebuilt motor was that I had her balanced and she ran like a top. When I eventually sold the Z I let both motors go in the deal and I wished I hadn't. It was a sweet running piece.
