Re: 454 vs. 5.3 efi vs. 5.3 carbed

What about the best of both worlds... the 8.1! lol just kidding i would stay away from that motor but i do have to ask did the 1 tons have a 350 option because i've seen quite a few on CL that have a 350 that looks like its original and not swapped in although they could've done a really nice job.

Anyways like someone else said if your towing you might as well stick with the 454/400 especially with heavy towing maybe just swap in a 4l80 and gain OD but if you do go with a 4l60 please for the love of that tranny get a new sunshell i can't tell you how many of those come through my dads shop i would put money on it that they keep the transmission business alive lol, Im pretty sure GM ended up fixing the problem on their replacement shells but you could always be safe and buy the aftermarket ones

As far as looks go there is nothing original we haven't seen with the old school stuff especially car shows =-p if you want to spend the $$$$ on the LS it will look worlds better than any old setup does
