So I’m about to rebuild the 289 on my 65 vert. It was originally a c code but has a 4 barrel on it now. I want to bump it up to 300+ horsepower. Planing on a new cam, port matching my iron heads that were rebuilt 3 years ago, try y headers, performer rpm intake, already have eldelbrock 600 cfm carb and hei distributor, and some other minor upgrades. My question is what should I look for in a machine shop. I’m in the Salt Lake City Utah area and I found a few shops that look good but I’m also on a budget and want to do this as cheap as possible. What exactly should I ask the shop to do? Should I compare various quotes?what should an estimate for this job look like?
