S-10 project started Finally picked up a 70,000 mile 1999 5.3 to start my swap. Truck is a 2003 ZQ8, extended cab. I'll be doing the actual swap over the winter on a long weekend (4-5 days).
Pulled the heads on the engine to verify what I have and that it is still serviceable. End play is great, cylinders are all fine. has the 862 heads.
So as I am working through my list of to do's, I cam across the issue of fuel delivery. My question to the group is this; Can I run the stock '99 Silverado fuel pump assembly in the S-10? We are not going the super high performance route. But are going for more torque and better mileage than the 4.3 we are replacing.
I already have to replace the fuel lines from the back of the engine as the knuckle dragger that pulled the engine hacked them off. So the replacement lines will get me back to the rear of the cab to splice into the existing set-up. My research says that the stock 4.3 pump runs too much pressure on the run side.
But if we run a Silverado fuel pump in the stock tank, and run the lines in the "stock" configuration. It should all be happy. OR am I all wrong on this?
Next item - can I run a stock set of oil cooler lines for a 4.3 on a 5.3 (SBC tech on a Jedi engine). All appears to be in the same physical location, would just make the hook-up that much easier.
Wiring/PCM - Going the simple route here. Having someone else making for me (still need a 99-02 5.3 harness & PCM). Since I have to make this live in a fairly short time frame, this would be the best way I think. Could use some thoughts (links?) on this part. Been searching S10 forum, LS1 Tech for other threads. What I found appears to be Plug & Play. Guy says all the gauges & tach will operate normally.
Cooling - running the stock HD S-10 radiator for now. Adding electric fans and pulling the manual fan. Running the stock replacement 5.3 pump.
Oil Pan - LH8
Exhaust - modded 98-99 F-Body manifolds, fab up the pipes. Found a great example on S-10forum.
Know about notching the frame on the pass side. Found good pic's on how much and were to cut. May have to nip the cross member (we'll see on that one).
I'll be running the stock 4L60E trans. Truck is having the rear end rebuilt on Thursday. I'll need to do the drive shaft yet with all new joints & carrier.
So as much as I think I have addressed "everything", what am I missing.
