I want to get a crate motor for a 79Z28 and would like some recommendations. I have a budget of 4k and have looked at companies like blueprint, year one, and phoenix engines. Have read good and bad with all of these. Looking for 400hp/400ftlb , i also have a company called AES in elk grove IL local to me that also sells a crate. Does anyone have any input on this. I side toward a vortec engine with roller cam/rockers.
