I'm not sure of the mileage of the cam and lifters. I bought the engine on Craigslist. The guy had no idea the milage of the car it cam out of. The lobes looked fine when I took the cam out. I don't know the rear end gear ratio and not sure how to figure that out? The carter is an AFB but there are no numbers on it to figure out what it is? The best description I can say is that at the stop position in first gear I stomp on it and it accelerates but about 2000 rpm it doesnt continue to really put you back in your seat. Once I get to 3000 rpm I shift to 2nd and the rpm's are still really high into the 2000/3000 rpm so I shift into 3rd, But if I'm next to a regular car they are accelerating way faster than me with me stomping on it. The points and cap are brand new. I will check if if all the plates are open on the carb this weekend. I didn't rebuild the carb but that maybe an easy fix if that's all it is. I'm going to post a pic of the carb to see if you guys know what type it is. Thanks.
