2000 s10 4x4 lr4 4.8 swap
2000 S10 4x4
I have a 2000 s10 4x4, and going to put a 4.8 LR4 Vortec out of a GMC to power it.
so far I have the engine in the engine bay waiting on a oil pan, engine mounts, and still trying to decide on how to wire it.
I ordered a oil pan canton came out with last year. I was going to get the mildon oil pan, but it has too many accessories to have to buy for it, the canton one uses the stock engines oil pan gasket, and windage tray.
the oil pan is suppose to be in the mail here sometime this week.
for exhaust manifolds I was looking at the sanderson CSLS1584x4 headers, it seems like the biggest problem for manifold swaps is the manifold clearing the steering shaft.
I had three exhaust manifold bolts break on me removing the stock ones. I managed to get one out with a multi-spline screw extractor, today I got in the mail a Lisle 71400 manifold drill template for GM 4.8 5.3 and 6.0. The screws broke flush with the head, and this tool can either extract whats left of the bolt, or drill out and re-tap the threads. I might post some photos of that if it works good.
I wanted to do the wiring as cheap as possible, is it possible to do a stand alone harness, and keep the functions of the dash, like the speedometer? I've contacted some wiring companies and they said to keep the functions of the dash, I would have to get a direct fit harness,
is there another way?
also the truck has a np236 push button four wheel drive and the GMC had a stick in the floor/ manual np246. both transmissions are the same, the 4L60e, I just kept the transmission out of the GMC mated to the 4.8 that came out of it, and was going to swap transfer cases, for the one on the s10
my question is: does the computer PCM control the 4wd on the s10 and GMC? is it possible to switch out the transfer case on the back of the GMC transmission and instead use the s10s transfer case that would retain the push button 4wd,
I've looked at adapting a np231 and maybe just using that transfer case with adapters from novak to have a manually shifted front differential.
I want to swap engines, but still want to keep four wheel drive also.
