re-arch of springs

[evan396]

my dad and i need some advice,the truck is a 1966 k-20 with a six cylinder and we are going to replace it with a sbc 350. we are going to have the springs repaired and rearched. we are pretty sure that the 350 is a little lighter than the six. should the springs be the same height all the way around? we just want to make sure that the truck sits level with the engine swap.we would also like to increace the arch by one to two inches if this would not interfear with the steering. would like to know if we even need to do this if we are going to use 33" tires or maybe 35" tires. jus

t so you guys know, we are going to keep the same driveline and the 3/4 ton axles, just the engine swap. thank you evan396
