LT1 swap, should I?

[Johnny Blaze]

Here's the deal. I have a 1971 camaro. The build plan is mild pt/ driver.
It currently has a tired 1990 350 truck motor with a performer intake, 600 edelbrock and headers.
On my daily commute, it averages 16mpg.

I would like to build a new engine, with a goal of 400 flywheel hp, or close, and to get milage up to at least 20, with a goal of 25mpg.

I could rebuild the 350, and a roller cam, vortec heads, however, I have access to a complete lt1 and 4l60e, wiring, ECM, etc from a roadmaster.



For the same money I can rebuild the lt1, and already have efi.

I know in the days of lsx, an lt1 swap seems silly, but in reality I can accomplish this for thousands of dollars less than a lsx swap.


So, any advice?
Will the lt1 meet my goals?
Anything to look Out for if doing such a swap?
