Idk if this makes a diffrence but the 318 actually came out of a 83 pickup. The motor is on a stand atm. Does anything change with that motor? It really sounds like its a matter of opinion or choice with the 318 vs 360 arguement. I'm going to stick with the 318 an stroke it to a 390 an bore the block .40 over. I'm going to stick with the 318 cuz i have a 383 block sitting soooo buying a 360 would just mean another motor sitting until I can sell it. I may plan on using nitrous for track use only permitting that the motor will handle it. The car will have a A833 for sure an a 8 3/4 axle for sure. Im new to this so any advice is appreciated. I am going to lighten the car as much as possible since it will see the track but i need to keep in mind it will also be a friday night cruiser. Thanks for all the input!!
