454 swap, do I need 1 ton springs??
 

I have a 85 k20 3/4 with a 350. I bought a 99 454. Will I need to put 1 ton front springs to keep the sag away because of a heavier motor.

I really do not want a rough ride with 1 ton springs!! what are my options??

oh i know im just saying weight wise if a half ton can hold one up no need to swap a 3/4

No definitely don't need to swap to 3/4 ton. Shoot my car has a 454 in it and its' not that bad.....

id say you did have to run bb springs in it though right? i can pull off sb with my the buick bb but the chevy engine is slightly heavier.

I would say the 3/4 ton springs will be fine.

K20 is a 4x4.....99.9% of all lifts do not ask about what engine is in it. The factory springs will be just fine.
