L31 (Vortec 5700) swap
I tied in, IIRC, at the distributor, alternator, and then at the big bulkhead connector for +12, +12sw, gauges, etc. I'll see if I can dig up the cutover diagrams I did for the project - truck has since been stolen. :(- benjaminearle

How did this thread get resurrected? I went ahead with the Vortec 5700 swap. Read all about it at: http://www.gmsquarebody.com/forum/showthread.php?t=5795- benjaminearle

Scotty, you're close but it's more like drinking your own urine (which, BTW, although gross, is sterile and won't do any harm - some folks do it while training for a fight and if stranded at sea it's much much better than attempting to drink seawater). If the engine is running properly, the...- benjaminearle

Mileage might not be as bad as you think if you keep EGR and run in 2wd for the most part. For the most part I like it in the truck. I truly love that it cranks right up in freezing weather and after letting the trans build a little pressure and heat you're off to the races. I wish it...- benjaminearle

L31 (Vortec 5700) swap
Well, my mileage wasn't as bad as i thought. I have no speedo/odo right now so i filled up and then tracked my trips with google maps, filled up again (at ~1/3 tank) and did the math. Looks like 11.3mpg mixed city/highway. Not so bad for an NP203 running fulltime and a THM350, on 32" A/Ts...- benjaminearle

L31 (Vortec 5700) swap
Ok, with the help of all y'all i got her on the road and today solved my giant transmission leak (kick down cable was completely out of transmission). I still have a funny drivability problem - when i mat the gas and really load it up it tachs up and pulls but then shuts off at some point (no...- benjaminearle

L31 (Vortec 5700) swap
Well, had a great weekend working on the truck and then...driving it. I got the pushrod drilled out to install on the brake pedal and got that buttoned up. Then got the driver's side exhaust completely hung. I'm loving my $240 Jegs pipe and muffler kit - especially after Midas tried to rape...- benjaminearle

IT DRIVETH! But, it shouldn't have. Searching for the giant vacuum leaks I capped off the two evap lines and still had a giant wooshing sound. Kept looking and finally found that the brake booster was leaking like a sieve. Not sure if it was a failed diaphragm or just a rust hole in the...- benjaminearle

I wish you success in your transplant. If i can offer only ONE piece of advice at this point it would be - label label label and document document document. Take way more pictures from way more angles than you ever think will be necessary and add labels to every wire you cut (both ends) or...- benjaminearle

L31 (Vortec 5700) swap
Figured out the 2,000 rpm idle - wasn't the vacuum leaks (which are still a-plenty). I had hooked up the cruise box and it had enough cable tension to crack open the throttle. I pulled it's cable and now have a very pleasant idle. The Dynomax mufflers may actually be enough now that i've...- benjaminearle

I found the temp line and think I've found the oil pressure line. I don't have the sensor plugged in right now (but never lose fuel pressure) because it restricted access to that giant bundle i needed to do some splicing in. Figured out the sender unit - it must have hung on something...- benjaminearle

L31 (Vortec 5700) swap
I'll check the ground, but it shares a ground with the fuel pump, and that's working. There's at least one splice in the signal wire - i'll check that too. Any idea which wire in the Vortec harness gives me block temp and oil pressure for the dash? A whole plug tower off - THAT's impressively...- benjaminearle

Fuel - check Oil - check Water - check Crankety crankety VROOOOOM! Making an awful squeal so it only got to run for 30 seconds or so (it was 12:30AM). Now to get all the intake stuff on (MAF, IAT, etc) and make sure the oil pressure sender is plugged in (how long should i be able to run on...- benjaminearle

Gas tank is now plumbed in and wired but not lifted (just in case something's screwy). Tried to use steel line but couldnt get it to bed (yes, using a bender) without folding so i broke down and spent the money on good soft line. So far the fuel system is the most expensive thing besides the...- benjaminearle
