I have an original numbers matching 74 Corvette LS-4 I will be rebuilding. When I bought the car, three valves were stuck and subsequently broke their corresponding pushrods. I tore the motor apart and found the pieces in the oil pan.

I have never built a motor before, so with a few books, I have started reading. I believe the block is already bored .030 over, if it is ok, I will leave it alone. I am getting the block ready to be tanked.

It is tore apart and all the freeze plugs and oil gallery plugs removed. I will have it tanked, magnafluxed, and mic'd. It is a 2 bolt main, I was thinking about using studs instead of bolts to make it a little stronger, so it will probably get line honed.

My plan is to squeeze as much HP out of the motor, while leaving the external original. Yes I'm going to use the Rochester carb and the stock heads, intake, and exhaust manifolds. I also would like the motor to not need any external vacuum while running pump gas.

Am I being to ambitious? Once I get the initial inspection of the block and know what I need to do, I will start the work. Any suggestions, or words of wisdom are appreciated.
