Ok, many of you guys on here have helped me before so this is obviously the right place to turn to

well starting the point of this thread off, I have an LO3/T5 combo in my camaro. The engine as it is runs strong and reliable, but my plans for the somewhat near future is a rebuild. For the best combo of fuel economy, power, and fun.

the question is however, what would the cash and time requirements be if I were to pull out the 305, had it bored .30 over, had the block machined, and putting in a light weight but strong rotating assembly complete with a full balance.

I'm mainly just looking for the price of machining + the bottom end parts
I can figure out the whole top end myself, but my inexperience leaves me hanging on the lower


I want to steer away from a 350 TBI swap(350 bare crate engine from jegs) because I honestly have it programed in my head somehow that the 350 will eat my gas, when I know it wont. but if worse comes to worse and a rebuild is too expensive for my budget I would consider this:
