Thanks Josh, 862 heads. If I keep the motor, my hope would be to find a clean southern 2wd 4.8 Silverado with the NV3500 manual, and tune it up ---

> [@Jon](#): > > The intake and MSD controller to convert a LSx to carb is like $600,seeing that you went with a gen 1 sbc. lol Yeah I know, but I’m a married with kids single incomer homeowner. But I have a plan to attend the Grassroots Motorsports $2015 challenge 1 year from today. I bought the LSx hours before I found the car i ended up buying, a 1982 Trans Am with 305 and 4 speed T10. The 350 build will be 1/2 the cost of the LM7 efi or carb. I might get around to doing a build thread this winter. ---

Hmm. I might seriously be interested in this. Do you happen to have any kind of test stand or maybe we can rig one up so I can hear it run? Have VIN? By partial harness, you mean chopped? Can you shoot me part/broadcast/casting [#s](http://www.nyspeed.com/usertag.php?do=list&action=hash&hash=s) from the block, heads, and ecm? Btw I live in NC I’m sure I can help you track down a southern truck ---

Stmotorsports: heads are 862 castings, I do not have a way to run the engine. The harness is cut, not sure if its enough to rewire it to a stand alone or not. I didnt cut it. I appreciate the offer on helping find a truck, but that would be a project after the Trans Am, so that’s why this engine is for sale, because I can’t do 2 projects at once, plus I have a great truck. Thanks for the offer Minglor, but I already have a freshened 4-bolt short block, Vortec heads, Crane cam, performer Vortec intake and Holley 4150 750cfm carb. ---

Guys this is already a killer deal, its a complete engine, you can part it out for more. Heck there is $150+ in covers alone. ---
