Must run on pump gas. Prefer to have TQ in the low end, and give up some HP at the upper RPM limits
I've decided that the SBC in there just has to go. I've got 2 LS engines to choose from but I'm having a hard time deciding. What does the board think?
2004 Chevy van 2500, 5.3l LM7 4l60, AWD rollover. Mileage unknown, oil looks good, radiator is full. It's drive by cable but missing PCM
No body panels are sell-able, no oil on the trans dipstick, rear axle looks good Cant be started
Whole van can be bought for $500 Craigslist deal no returns
2000 2500 Chevy truck 6.0l LQ4 with iron heads. 4l80 light front end hit, rad is fine, rusty truck. not sure why its in the yard
no dipstick, I grabbed one from a SBC and put it in the dipstick tube, no oil. I looked in the filler cap, no sludge. They said I can pull the rocker covers and spin it over by hand. no starter to spin it up for a compression test. waterpump turns by hand, alternator has a little drag from corrosion, so it spins with a slight drag
I have to pull the wiring and PCM, they will pull the engine. Only thing I see missing is the starter and dipstick.
I can get the engine, wiring and PCM for $450 From a junkyard, no warranty as they cant start the truck to test the engine
Thoughts on what would be better for my application and goals? Thanks for the help guys this will be my first LS swap Still putting together what works with what. The +.400 crank on the LQ4 has me concerned. From what I'm reading the 700 will bolt up if I slot the flexplate to fit my torque converter. Not worried about the wiring, more concerned with the fitment using my JTR kit, the ability to keep the 700.
