Pretty straight forward deal,motor mounts (both frame and engine),bigger radiator with a fan shroud and V-8 fan,new exhaust of course.
You'll need brackets for your accessories, PS pump & alternator is all it looks like there,my '69 didn't even have power steering.
If you were to go big block you'd need a big block heater core.

 

Thank you for the info ! I’m also putting in a t5 5 speed hydraulic. I think I have a great platform to work with. This car is all original except for the wheels. I paid 4500.00 for this car and it is in great shape overall. I have no idea what this car might be worth so I am keeping everything I take off the car I always wanted one and finally this one landed in my lap lol any does and donts will be appreciated I will post pics of the progress

if you plan on using a T-5.
If you plan on making much power at all I'd stick with an old school 4 speed Muncie or BW T-10 myself. Or if possible get all the parts for a T-56 six speed conversion.

A good running mild built 350 can destroy a T-5.

 

I agree with Y2Keglide. stick with a Muncie and then add a gear vender over drive unit to it . I love mine.
with a 3:55 rear gear I can run 80 mph and turn 2600 in 4th OD

 

OP

+3 on the T5 being a fragile trans behind a V8 bigger than a 305 2 brl motor. You can put around with it but driving it....well like you likely want to behind a 350 ci V8 and it will be short lived

Consider a Muncie 4 speed or a TKO 5 speed if you want a OD trans

 

Thanks for the info y’all!! I will keep y’all posted on the process !
