    i am looking for the best way to get more performance and most importantly better gas mileage. I know i can build my 350 tbi ('91) and make more horsepower than i ever could with the 5.3. I would like to see 15-18 mpg rather than 12-15. What do i need to get for this swap? which manual transmission works on the 5.3? Anyone have a 5.3 on this forum for sale? thank you
