Scored on a LS6 intake manifold, batwing oil pan and water pump this week. Old A/C is removed and ready to install Vintage Air system. Need to find a dipstick and oil pickup. Engine bay paint is well underway.

Didn't get an alternator with my engine. Will any LS work or do I need a certain amp? Going to use the Holley bracket for my PS and Alt. on driver side.

Made some progress today. A Arms are back in. Vintage Air box is temporarily mounted and need to make a few adjustments. Tried to mount the jeep box and the u joint I purchased from Borgeson is to small. Have to send back and maybe go with rag joint.

Need to find a set of 2001-2004 Corvette exhaust manifolds. Not a lot of options for headers with this swap.

How come the Jeep box? I've seen comments before on people using these but, what makes it a better option than the factory steering box that the vette came with? Not just on a Corvette. Juuuuust asking.

The jeep box eliminates the leaking cylinder and 2 hoses. Here is a good write up on the conversion. http://www.vettemod.com/forum/showth...highlight=jeep

You asked earlier about which alternator to use. If you are using the Holley bracket, you must use the pickup style alternator. It was a great idea by Holley to do this. Truck alternator are plentiful and relatively inexpensive. I used this bracket and setup on a 58 vette I am restomodding.

Good find on the LS6 intake and pan.
Btw, on the pan, you can reuse the o ring style gasket, but the manual reccomends putting a light coat of rtv about 1" long at the 4 corners where the front/back covers meet the block.
I've got an ecopy of the LQ4/9 manual if you need it.

Picking up my LQ4 block today to swap into my 71 Vette. Long road ahead.

@ garys 68: can I get an ecopy of that manual?
Thanks

Send me an IM with your email address. Kind of a big file, not sure if I can attach it here.

Don't let anyone bullshit You , the Truck manifold will make as much or more power than a LS 6 . As long as Your Cam is 225* duration or less @.050. The smaller the Cam the bigger the difference in power . And the truck Intake will fit under the stock Hood for Your Car. I got one in My Car , 1970 with a 73 up-Hood. Also if You Don't want Hedders, LS6 exhaust Manifolds fit like they were made for the Car. Stan

Are you in the Louisville area? I think I see you post on the Louisville driver's thread on CF sometimes...

Anyways, give me a shout if you need a hand sometime. I'm still fine-tuning my swap.

Lets see a picture under your hood. I needed to go to a cable TB anyway and got a good buy on the LS6 manifold and TB with the injectors and other components.
Ordered some more parts today. Ordered the LS swap kit from Bowtie. http://www.tvmadeez.com/ls1_cam/ and a new filter and gasket for the 2004R.
Will be working on the jeep steering this week and changing the body mounts in front. Another while I am there. Glad to be putting more parts on than taking off.

Do I need the normal 145 amp or the 200 amp? Looks like $25 difference. Also going to need an adapter plug as my old set up was 1 wire.
