im in the process of rebuilding my engine... it had a knock and I found out a few piston skirts were broke. anyways, while it's out, i figured i'd make some upgrades. I was thinking about new heads, a bigger cam, intake, and maybe a stall converter. I was wondering if anyone had some input on the best combinations for these new parts for my 355 tpi? I also have the stock 700r4 so im not sure what i will be limited to. I am also debating wheather or not it would be a good idea to forget about building up my 355, which also needs to be checked over by a mechanic, and go with an LS1/6 speed combo.
