After scouring the internet for hours I am throwing my hands up and asking the experts.... Does anyone have real experience with this engine? I have a stock L29 engine, I would like to get a little more power and a nice lumpy idle. I have heard that the ZZ502 cam is a nice swap. It would be great to use the stock non adjustable stuff, But I am not opposed to swapping out the stock stuff for screw in studs and adjustable rockers. Can anyone point me in the direction of what I would need for this procedure? (part numbers would be great!) I plan on using a 770 carb, with an aluminum intake and old school distributor with a melonized gear. I have a beefed up Th350 with a 2400rpm stall, and a stock 10 bolt posi with 3:42 gears. I dont need it to be too crazy, just a muscle car idle with some tire frying capabilities.
