Hi all, I recently acquired a '67 Parisienne and it has a Chev 307 in it, replacing the siezed 327 that came in it originally. I'm wondering what, if anything I can do performance wise with this engine. I've heard this can be a bit of a dog, but can be maximized out at 235 hp. If anyone has any ideas on ho...

I have just replaced the motor with a new crate engine from GM -a 350 small block - but car is not running smoothly. The carb has just been rebuilt but is still rough when idling. Should I replace the old carburetor with a new one?
