Q: I’m getting ready to build a 406 small-block to put into my Camaro. My question is about the use of block filler. I’ve read that if you fill the block to the bottom of the freeze plug openings, that it will increase the cooling ability because this limits water flow to the oil pan

Q: I have a 1970 Lotus Europa S2. It’s a mid-engined, rear-wheel-drive car. With a little cutting and welding, I managed to take a Ford 302 (bored .30 over) and nestle it snugly behind the firewall. The engine runs like a charm, but now I need to find a transmission that will match the Ford
