ls engine swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just got a complete 4.8 out of a 2007 GMC Sierra to put in my 56 Cameo. What are you guys doing for a radiator? Has anyone adapted the radiator and fans from the donor vehicle to a task force truck?

I talked to Jesse at wait4meperformance and I am going to send the harness to him. I see others on this site have used him and thought he was alright.

The truck radiators are too wide without a custom core support. I also have an LS camaro radiator and it is also too wide to fit very well. I am thinking of trying to use a bolt in aftermarket aluminum replacement intended for SB chevy and try custom hoses. If anyone has a better idea I would also like to know about it...

Here is my setup, 5.3L from 2002 Silverado. Aluminum rad that mounts in factory location, hand made shroud and electric fan.

Did you take the crossmember out of the truck that the engine was in originaly? I am about to start my Resto on my 56 Short Step Bigwindow and I am going to put a 6 Liter and a Kenny Bell Supercharger on it. The big question is how does the engine mount to the frame? Thanks for any insight or help you can give with this.

No I didn't get the crossmember for the truck. my truck has a GM clip in it with stands on the crossmember for a smallblock motor mount. I don't know whether to use the adapter plates to mount the LS or redo the stands to use the stock LS mounts. Any suggestions?
