OK, here I go. Bought the proper carb for the engine. Sent the vin to PHS and surprise, it IS an HO car. From what PHS says, it is one of 2455 1969 350 HO with manual transmissions. From Hagerty, it is 1 of 112 convertibles that came with the HO 350.
Just going to do a stock rebuild. machine shop is 8 to 10 months out so I'm pulling the heads to get them done first, speed up the process and take a look at cyl walls. Hopefully no cracks, 48 heads don't look to be cheap to replace. Ran all the date codes and the block, heads and intake are all good. HO motor is not numbers matching to the car, but the fact that I got an HO 350 from 1969 is pretty awsum I thought!
