if i were you i would consider a 5.3 or 6.0 vortech it is verry similar but much cheaper then an ls1, with the extra money you can do some heads a cam and a fast 90 intake manifold and make alot more power then you would with a bolt on ls1.

 

call dave at genium performance in largo. best price and best work around

 

forget the LS1. You have to pretty much gut the truck and redesign everything.

a 5.7L vortec (350) will swap in using the same mounts, and the tranny will bolt up. Just need the wiring harness from the 350 for the extra 2 cylinders.

check out zr2usa.com and look up ls1mike

 

that sounds way better

 

I havent read too much on the lsx swaps in dimes, what exactly has to be redesigned? Not trying to be a smart ass but from what I can tell it should be just like any other v8 swap, specific mounts, headers.

I have read the oil pan can be in issue with the LS's, but a good torch or plasma can fix that.

The major PITA i can see out of it would be the 10 miles or so of wire harness, but that could almost all be avoided with a carb setup and a front drive dizzy, provided of course the funds are there to do so.


And If the major thing is all the wiring, and you're on a budget why not go with a 1st gen sbc?, with the influx of all the LS parts out now the "dinosaur motor" is only going to get cheaper to build.

 

do lt1 swap!

 

so i can be cool like you?...hit me up some time homo

 

The LS1 swap just needs new...everything. Wiring/computer/accesory mounts, and then on top of that, you gotta create some engine mounts.
I'm not even sure it bolts up to the stock tranny (although I think the 4L60E recommended max is ~300 hp anyway).

Without alot of work, the 5.7L would be the most straight forward swap...and if you really wanna get exciting, you can always bore it out to a 383

But either way...probably should rebuild the 4L60, or go with a 4L80.

To see the LS1 ZR2...clicky

 

should be the same bellhousing pattern on the tranny, so if it's a 4l60 it will bolt up, but it will not be able to handle the power unless it gets rebuilt.

 

personal expierence? I wanna hear this
