I just noticed that you may change the engine from a 283 to a 348? Car won't be stock anyway.

If that is the case....why are you wondering about keeping a turboglide trans?

348s could be real bears that bent pushrods alot.

Why not just put in a good 350 and a 700R4 and really have a good cruiser?

Just my .02..........

In 1958, the 348 was offered as an option, the 700R4 was not born yet.

Thanks guys,
I have my cars strictly with original options, but just the ones I like, I don't throw on any accessory, I don't like my cars looking over the top.
I don't mind updating mechanical for reliability or drivability, but they look correct from the outside.
For example my 52 powerglide engine, I fed a 54 crankshaft (stroked 50 thou), oil pump, cam shaft, pistons (100thou oversize) and rods, and rocker-gear into the 52 block. A bit of extra machining was necessary to fit high lift camshaft and main bearing thrusts, plus a few extra modifications that makes it full oil pressure, with a bit more power for a reliable cruiser.
The 58 would have to be reliable and drivable as well,
Ian.
