Pre-85 block or new LT1-LS1
Pre-85 block or new LT1-LS1. Is the hastle of swaping in a new LT1 or LS1 worth it? Is it better and the old style engines? My L69 is carbed so it must be carbed. No EFI...

because I don't want to deal with installing all the electronics that come with EFI...Plus, carbs are easier to tune.

Ok....forget about induction for now. Is there any benifit from one to the other about the engine blocks or gemometry that make one better than the others? Or can any one of them produce the same amount of power. Are the new ones more fuel efficient in any way? Thats what I mean by better...

LS1's are getting even better gas mileage.
Also, since you have a carb car, it will actually be easier to swap in since the wires that you need to splice in are the only ones in the engine compartment as it is.
