Food for thought. I’ve been following a guy on YouTube that is swapping an LS into a Corvair using a Cadillac transmission. The advantages you ask? LS power with an overdrive transmission. The LS fits sideways, might be an advantage, all the parts would be available over the counter. I’m just spitballing here, or has this already been done?
My ride runs great so no changes planned. Just stirring the pot.

I remember purchasing a TH425 from an individual who had planned on using it for a mid-engine conversion of a Vega coupe. Ran out of money before finishing it. Neat idea.

Nelson, the LS is the replacement for the original small block chev engine, used in most GM stuff today. Most common 6.2 liter (~~372CID) shares only bore centers and a couple of internal parts with the original smallblock. Time will tell if it's as reliable. The original small block came out in the 55 Chev, production ended in 2003.

And on looking further, the 6.2 may not be the most common....

I think he's talking about using a newer Cadillac transmission, probably the 4T80-E, which mounts the engine transversely. It was designed for up to an 8000lb vehicle, so I don't know how it would hold up to 12000lbs. Has anyone tried it?

Thanks Johnny,
Great engines as I had one in my 55 Chevy convertible, a 327 in my 69 Vette and a 400 in a 78 van, all great engines. But the one in my 75 Vette is a disappointment as that was the year for all the government mandated emissions. Maybe I can replace it with fuel injected LS.
