Hi,my car is Chevy caprice classic 1991 sedan,and engine is 305.I think if i swap engine to Chevy LS engine.But i dont know every detail what i must do if i swap LS engine to my Chevy.Who can give to me detail stepbystep,thanks

 

Id suggest upgrading the 305, maybe with aluminum heads and a bigger cam, And if its TBI you could get a bigger throttle body. or just port the old one.
