hi ive been here a few times but this time its for real i have a 94 dlx single cab 4x4 and yesterday i got my hands on a 2000 escalade with a 5.7 and everything works in the caddi but im gonna take everything i need from it but i guess im wondering if the front end of my truck is gonna be strong enough to hold the 350 and what all has to be changed.

buy frame renforcements and for fitment be better if your truck has a solid axle and plate the frame and steering box

The suspension is fine 200 lb difference if you were originally a 4 cyl (even less if you are taking a 3.0 out). The automatics are close to the same weight, maybe 300-350 lb diff if you go from a 5spd to the gm automatic. If you feel you need it put a 2 in ball joint spacer and twist the torsion bars up a little. if you stay with the IFS you will have to modify the oil pan a little or drop the front diff and cross-member about 2". If you plan on thrashing it you will want to upgrade your axles unless you plan on driving it like mamaw in her Cadillac LOL. Moderate 4-wheeling I would advise an 8" Toyota sas for the front being the weakest link in the chain is the 7.5 front differently. I have learned that a rear locker is desirable as I am spinning the rear tire easily when driving conservatively with my 5.7 tbi, Toyota 5spd, 4.10 gears, 31.5 tires and your Vortec has about 70-80 more horsepower and ft/lbs torque

Oh yea a 3" body lift is a good idea to make a little more room for a V8 and an sas will make more room for exhaust manifolds getting the torsion bars out of thee way
