Newbie engine swap question

Newbie here!! Hello to all. My current project is a 1980 Pontiac Le Mans wagon. It has the W engine code so I have the little Pontiac 301. I am new to changing from Pontiac power to SBC. I was wondering if anyone can tell me what I might be up against. I do not know what tranny I have other than an auto. I do not know what it will handle. I plan to install a 300 horse 350 SBC. Anyone know what motor mount changes I have to make, and will my auto tranny handle this? Thanks for any information!!

You will need frame mounts from a Monte carlo or Malibu for the SBC. 78-mid eighties. The same for exhaust and most bolt ons. If you have a Multi pattern 350 trans you will be lucky. Otherwise you can either adapt the BOP trans pattern to the SBC (simple plate and TC spacers) or get another Chevy trans of the same type as is in the car.

Engine swap.

In a car like that, it might be more fitting to keep it pontiac powered. A pontiac 350, 400, or 455 should drop right in. The TH 350 should be able to handle it, as long as you don't overheat it.
By the by, if you're getting rid of the 301, I might like to buy it. Some call me nuts for showing interest in the little wheezebox, but in my mind, an engine is only as good as the crafty mechanic who built it.

i almost agree with this guy.. except the part about a 301 being any good!!
for the same price you can have a stout 350 with more avaliable bolt on's!

KEEP IT PONTIAC SUKKA!!! IT WILL DROP RIGHT IN!

unless you like fallowing the chevy croud,
us pontiac guys like to rise above them!

Engine swap

Hey! Take it easy on me! I already know I'm nuts!
I wish I had a better option than the 301, but for my brand of racing I have to keep it under 305 cubes.
