Well, it doesn't matter anymore..well not for now lol. The engine ended leaking out ALL the oil and my first day back to work (since Oct due to a back injury) on a dark desolate road so i didn't have any lights to see the smoke by and the motor started knocking so i stopped and pulled over and looked under the hood and the knocking was extremely loud (coming from the back of the passanger valve cover (either cylinder 6 or 8) like a rocker arm was knocking the valve cover but it's all stock, just giving an example of the sound. Got the car towed back home, it was completely empty oil wise (oil ALL over the block/fenderwell) and ive decided to just park it and buy a crate motor when i can afford it. until then it will just some some minor body work. It still runs, but i dont wanna push it because i will probably rebuild the motor with a 400 crank and 350 pistons (is that compatible/possible) and come up with some strange displacement through boring. lol. If i use 400 crank/350 pistons, what would my displacement be?
