Carbureted LSX forum - 2005 avalanche 5.3 into an 85 K5, What do I need?

What parts would you recommend for a "stock" build?

Its an 85 k5 blazer, 4x4, 700r4, 3.73 (4.10 or 4.56 soon) 35" tires (maybe 37" later if we regear).

Motor is an 05 avalanche. Less then 100k on it.

We plan to drive it everyday. We are going with a 5.3 because it is better on gas, and more reliable then the 350 that I had in it.

MSD box 6010 or 6012?

Carb- what size?

Intake?

I gave my brother my truck, and apparently I am funding the project too. lol.

Performer intake, 650 carb, schoenfeld makes swap headers for the 88-98 truck, but we found they fit the older full size just right, otherwise the stock manifolds may serve well.

Oh yes, look at the crank sensor, black is 6010, gray is 6012 for the ignition.

What about the flexplate? Do i need a new one, or just the spacer?
