the motor mounts were moved up about 4in. gave me enough clearance w/o hitting the radiator and still had room to pull belts. the core support is going threw some cutting to sit the rad. where the a/c condensor use to be and give me more room for bigger fans. cam is a 483 lift. nothing speacial. i did not have to do anything to the drive shaft everything fits and has not been messed with. although it would be real nice to have a 1 piece insted of a 3 piece shaft. wirring is gonna be a bit of a bitch but in the process of trying to figure out what is needed and what runs off of what. still a young guy learning alot. biggest thing ive learned is i will never own another chevy!!! also if anyone has a windshield or any other parts u think i could use to get the truck back on the road let me know. money is tight and i need a running vehicle so i can find another job.
