I remember back in the 80's someone saying it was illegal to put a V8 in a Datsun 280Z
Never knew if it was true or not.
A friend in high school put a Ford 460 into a 1978 Mustang Cobra II, he had to move the firewall back 4 inches to do it.
Nope, there was a kit. Local guy had one with a 350 and a Muncie M-21 4 speed. It was a fairly quick little car, but he cut corners, and started with a rusty car, so when it developed problems, it got parked and rusted away quickly.
I think I built maybe a half dozen small block Chevy V-8 Vega hot rods, a 10 bolt Nova rear end worked if you got the right offset wheels. I could snag a Vega with a tired engine, and either find a wrecked Nova, or a 4 door Nova, go to the dealer and buy the engine mounts and oil pan for a Monza, and have a fairly quick little car, cheap. On a couple week nights, or a Saturday.Had a deal with the local muffler shop for a dual exhaust setup. A local speed shop usually had aluminum intakes, and budget cam and lifter kits, with a roller timing chain. My cousins (distant) own a drive shaft shop. I eventually built a really stout one, it had a relatively well built 400 small block, a built TH 350 transmission, and I found a 4.11 gear for a 10 bolt rear.
