Even if that BBc was built with low compression at 8:1 it should still be a blast to drive and should smoke those tires all day long. The amount of work it took to get that motor and trans into that car, and the details like the dial oil filters etc I bet the motor build is solid with no cut corners. I bet your timing is way off and your carb needs to be tuned. I suggest you get a book. DVd on tuning holley carbs and read as much as you can, and buy a good timing light and again get a bok and read. You bought a unique car that is always going to be a project. Its not like you gonna go to an auto store with most idots behind a counter and ask them for a part for your car. Everytiing is unique and your mecahnical abilities are gonna have to improve greatly if you want to put any miles on that car.
