Thanks guys. I'll read up as much as I can. I know $2k ain't bad, but if it isn't done perfectly, I'll throw a fit, so I'll just do it myself. I want to gather as much information as I can for this swap.

I can get an LM7 for about $400 through my connections. This is complete with harness, PCM, and all accessories.

I'm anal about wiring, but I don't have the patience to sort through all the diagrams and what not. Maybe I'll try to find another truck like mine in a junk yard and pluck the harness and I'll give it a try.

I'll look up more info on the 4.8 flywheel to use the NV3500 behind the LM7, thanks for that piece of the puzzle.

I've got a parts list for the LM7 swap I was going to do in my '56 Ford, so I'm familiar with the Walbro pump and Corvette filter. No biggie.

As far as the mounts go, I just didn't want to have to move the transmission forward or backward, resulting in shortening/lengthening the driveshafts, modifying the shifter location, etc. It's not a big deal, I just want to keep that stuff stuck.

Those Dirty Dingo mounts look good. I hadn't thought of slotted mounts. In that case I'll just make my own mounts and save myself $100. I have a CNC Plasma Cutter at my disposal, so that's easy.

One thing I forgot about... I'm wondering if the stock LM7 or other LSx exhaust manifolds will clear the OBS frame/steering? I don't want to have to buy headers unless it's really needed.

Like I said, this thing will be stock besides dual exhaust and some Spin Tech mufflers I've got laying around. Might get a tune, but I don't think I'll need it. I don't plan to drive it hard and risk trashing the NV3500. I just want the extra pulling power when I'm towing, and to pick up a few mpg over the gutless 4.3 V6.

Thanks again

Get a flywheel from a 4.8 and a clutch kit also. And as for the pilot bearing, you can get one for a 2010 ss camaro.

Talk to Chris at LSX Powersports about your wiring harness.......

Walbro GCA 758 F20000169 255LPH fuel pump is a direct repl. for stock chevy pump for your truck....got mine through Ebay for $98........

If you pick up a 5.3 with a return line on the fuel rail you wouldn't need to do the corvette fuel filter/regulator, it's only a matter of buying the right connections seen here



The rest of your questions have been answered spot on by all the other fellas

Kwik Performance makes access. brackets for swaps...they have a bracket that will allow you to use your orig. A/C pump.....
