Anything is possible...BUT thats a hot air motor so you will get better information and help in the hot-air/before black section

 

[thadeal4real]

motor mounts and transmission are going to be the things to figure out first

why bother? put a LS engine in your truck.

 

[novaderrik]

it can be done, but why?
a stock HA motor won't be much of an improvement if you have a TPI 350 out of a Camaro or something in it now, but may be a slight improvement if it's the stock TBI 350...

I vote LS engine. 86-87 GN motor is the one you want for "cheaper" power
Or even a 454SS clone.

Do what you want, whatever makes you happy or challenges you or is fun. Don't worry about everyone else. If you want a truck with a hot air in it, cool. You want a truck with an old staight 8 Buick in it, cool. Hot airs have come a long way with turbos, intakes, headers and up/down pipes, alky, etc. They can be made plenty fast. You have the engine and the truck, so why not!? However, as it has been stated above... LS would be cool. I have been itching to do an LS build, but can't convince myself to put one in my 85. It'd be Un-American and blasphemous.

Just kidding LS guys!

Cost wise, performance wise, and ease of installation wise, you'd be better off with an LS swap. 5.3s are cheap, and later down the road you have multiple options to upgrade the performance.
