Thread: Gen I 350 - Performance & Gas Mileage?

Tweet

If you don't have any engine parts yet---think about getting a 350 out of a 96 or later pickup/tahoe/suburban---they made excellent power, decent milage---carb manifolds are available


But---lopey idle sound does not equal milage

Thanks for the advice guys. Seems like the LS is well recommended around here. I would want to stay carbureted if I went with the LS motor. What makes the LS so much more efficient?

I'll have to live with the gen I for a couple years though, so I suppose it's best to avoid spending too much on it and simply install a cam and manifold and clean up the heads a bit. I was hoping to get some advice within these constraints.
