I have a 86 k10 with a 305/700r4/np208 with a one legged 10 bolt with 3.42's.

I'm looking at getting a 350hp/400ft/lb crate from Carolina machine.

I'll be running 31x10.50 or 33x12.50 for tires and was wondering if I should build my stock 10 bolt or spend the money and do a 6 lug 12 bolt or 6 lug sf 14 bolt .

so far I found a 6 lug 14 bolt semi floater with 3.42's from a 88 3/4 ton chevy on craigslist for 100 bucks.
I'm use to already having a strong axels coming from a 1990 454ss and 1987 camper special crew dually 4x4.

thanks for the help
