I need two blocks, the project I bought had popped frost plugs. I hoped for the best but after pulling the engines last night and removing the intakes I have bigger cracks than in a whore house. The blocks are GM bow ties with a bore of approx 4.58 using a cheap caliper. I will mike them later today to be more acurate and post the block casting # and a few pix. The pistons have no markings on them to tell me if they are oversize so I am asuming that they are std. Can I use a 427 tall deck truck block, I have no idea what the bore is on a 427

Well, Sounds Like You Got A Nice Combination. I Believe Your Best Bet Would Be To Bite The Bullet And Buy A Dart Block, Transfer All Your Good Hardware. A Tall Deck 4.500 Bore Dart Runs About 2k.
