I just got my 1970 Lemans started after 10 plus years of sitting (thanks for the help). I drove it around the block and the engine feels strong, but I was reading about a 383 stroker kit. Has anyone tried this product. I know not many of you have the pontiac 350, but any advise or thoughts would be helpful. Also when I drove it around the block I was unable to shift. I have a Saginaw 4 spd. Could this be the synchro or could it be a linkage problem? It shifts ok when the car is stopped and not turned on. Should get the transmission rebuilt when I have the engine out anyways.
