i have a 99 ls1 street rod 373 detroit tru trace rear end. long tube headers and programer and 130000miles on motor i would like to pull it and re do it what should i put in to the motor i have a 1500 budget

 

A re-ring with an aftermarket cam swap and a used LS6 intake manifold.

 

I would change out the rod bearings, check the main bearings, and mic the crank too. Then put it back together with a new oil pump, hardened pushrods, new valve springs, and new GM replacement lifters.

 

what size cam would be a good set up. it is a six speed with a/c . and do i need to change the springs on the head with a cam swap

 

where can i get a cheep ls6 intake. and does anyone know where up can get cheep ls1 parts

 

The Futral Motorsports F13 is a great cam. You need to change the springs, oil pump, timing chain set, springs, and pushrods on a cam-swap. Most aftermarket cam kits come with everything you need. With 130k miles, I'd also change the lifters like Al said.

You can find a used LS6 intake manifold here on the internet. Welcome.
