85 ls swap

[bm2000]

Hey guys! I'm in the planning and research stages of a ls swap for my 1985 c10 and I'm Hoping you guys could help me out. I want to build a reliable driver as simple and cheap as possible. Which would be more bang for the buck, 5.3 or 6.0? Automatic or 5 speed? Which mounting kit is the best. What fuel pump will get the right amount of pressure to the motor? Can I get away with keeping the original fuel tank?

Sorry for all the questions but any help you guys can give me would be greatly appreciated! Thanks!

For a DD I think the 5.3 would be a good bet. You can swap in 4.8 flat top pistons to the 5.3 you can not to the 6.0, The 6.0 does consume a fair bit more fuel. The 5.3 can produce plenty of power especially with a cam swap.

Brandon,

Look me up on FB via my signature. I have 6.0/4L80e in my '87. I can tell you everything you need to know, and how to get the cleanest install. I sell a mount kit for $75, shipped. You can look up my intro post to see the whole deal explained.
