Been meaning to ask this question for some time now. My 64 SD convertible originally came with a powerglide. Sometime prior to my buying it the tranny was changed to what I think is a 350TH. From the attached pics, am I correct? Casting number is 8640300 with CFD1 below it. There is also a circle containi...

Has anyone had their exhaust manifolds ceramic coated? There is a guy at the swap meets who does this but I can't find his card. Seems to me he can coat them to look like cast. If anyone knows of this guy let me know please so I can get mine done. He is always at the Ancaster swap meet ! Thanks a million Kevin

Per the feedback in a previous thread, it seems like the consensus is that the Carter 4028 AVS was likely the original carb for a '66 Beaumont 275hp 327. As I know nothing about carb's, my question is... Any thoughts on how the performance of the Carter 4028 would compare to that of a Carter 9625?...

I have a 1967 Pontiac Beaumont with a motor that cannot be original, so I am trying to find out what it is. I was told it was a 327, but not sure.

Some questions regarding the equipment that came with the L30 250 hp 327 and the L74 300 hp 327 Acadian Beaumonts in 1965. Did they come with 12 bolt rear ends like the L79 350 hp car? Did they also come with thermostat radiator fans ?

Hey guys, well previous owner ran 20/50 QS oil in this motor for years. I am thinking of changing it in the near future. I know that the clearances in these old big blocks allow for a heavier oil but is 20/50 to thick? It came from a hotter climate compared to where I drive it now (Victoria). I idle at around 2...

When the person I bought it from purchased it in 2003, he changed the plugs, points oil and filter and started it up. It ran well after it warmed up...
