https://www.shop.cliffordperformance.net/68-Chevy-235-261-Combination-68C235.htm I'm thinking of getting this. There are no reviews, so I thought I would ask here. Even if you don't have this, do you have any opinion? I have to spend money on a carb/ exhaust anyway so why not upgrade.My 235 has a recent rebuild but prior owner didn't get to this point.
