Questionwould a 350 motor fit with a 700r4 tranny?
into the 62.And if so .
what would i have to change out?
AnswerHey, Tony:
Such simple questions often lead to book-length answers!
But I'll keep this one short and general, and give you two links at the end that will give you answers in much more detail.
First off, if it's a Chevrolet 350, and not one from another GM division, the 700R4 will be a direct bolt-up. Otherwise, you'll need an aftermarket adapter plate.
The Chevy Powerglide and manual trannies that would have been stock in the '62 are the same length as the 700R4, although you may have to relocate the rear crossmember. The output spline on all the trannies are 27-tooth, so your front yoke will slip right in. The 156-tooth flexplate which was used with the PG will fit the 700R4, but the 700 uses metric attachment bolts for the plate.
The 700 uses a cable-actuated throttle body (not vacuum, like the PG), and you'll have to procure and wire a lockup switch for the torque converter. There is an adjustable length throttle valve cable available; I'd use it because the length of the cable is critical to proper operation of the transmission.

As you can imagine the parts list for this swap is rather long, but it's all little stuff and a bit of ingenuity and patience should give you a nicely-engineered, sweet-performing swap.
I love '62s, and had a nice Candy Apple Red SS back in the mid-'80s.
Good luck!
