The girlfriend and I have a 79 z28. The car runs, but needs a good bit of work. I cannot get interested in the project though until the thing is fast and fun to drive. I am used to light cars, these 2nd gens are anything but that. I am looking for some advice. The car has a motor that does not burn oil or do anything funny really, it has good compression, even between all the cyls. but it is a low compression motor put together in the 80's out of spare parts. It has a 650 holley, and headers, and a decent intake, but has a dog of a rv cam (don't know specs) and the car is totally gutless. It won't even spin the tires on dry pavement. I had a 2nd gen myself awhile back and it had a junk crate motor in it that did not make much a ton of power either, but it had a steep rearend gear (maybe 4.11). That car was fun but sucked on the hwy. I want to stick with the 3.42 since it is a good compromise and already there, I don't want to put money into that. I am trying to figure out how much power I need to match the "fun" factor the car with the deeper gears had. I know that is probably hard to do. I don't mind sticking some $$ in the motor, but obviously past a certain point there is a lost cause. I was thinking about maybe a 10" 3,000 stall, somewhere around a 270 cam and up the compression to maybe around 10:1 I have someone helping me do the engine work and they suggested porting the heads I already have since they know someone good at it. I know many here have built tons of motors. I am not looking to win at the dragstrip or race new 400hp cars, but is it going to be fun enough to be worth it? (or should I just save a extra couple grand and go with a 400hp crate motor). I know I only get one shot and don't want to waste my money for sure. Any advice is appreciated!
