Question type: Maintenance & Repair

I need a new engine in my Tahoe.  
Has the 5.7L 350 in it now.  But I
have an available 305.   Will it work?

1 Answer


It will if you redo all the electronics to match the 305, but I would advise against it, the power loss will be very noticeable and the fuel mileage is going to drop considerably, plus the electronics redo is going to be a nightmare.

    I have a 99 Tahoe and in park the engine sounds beautiful. But as soon as you put it drive it won't run over 10 mph. Then it stops and starts over from 0 mph back to 10mph.
