Re: Enginge/Trans opinions
I did the LS/4l60e swap. But....
Because its not a daily driver I've come to realize the LS and Overdrive tranny aren't really necessary. What do I care what mileage I get? Even with the LS and overdrive tranny I still only get about 12mpg....top off, 4" lift, 35" tires and 4.11 gearing (4.56 would probably be better.) What's the overdrive doing for me? Not much I figure. Don't get me wrong. It's a cool thing to have and show people the swap. But it's not a must. A really clean engine compartment with a carbed 350 or 454 would be just as cool! If I were to do it again.... probably a 454 (or 383 for easy tranny mating.) Keep the th350 or get a 700r and buy a cheap ($50) adapter to mate it to the np205. I like cruising and saving the work from shifting. Wil
