54 corvette suspension questions
 

I bought a '54 GMC pickup and have been following the s10 swaps and purchased a long bed but I then stumbled on a variety of corvette C4 and C5 suspension swaps which is what I want to do. I have decided to buy a wrecked C5 donor and use both the suspension and drive-line with the LS1 understanding that I will have to channel the bed to accommodate the rear end mounted transmission. I realize that this is way out there but I do have a full metal shop and am not intimidated by the fabrication time required.

My question is, do I box the original AD frame and add the C5 suspension components as the aftermarket suppliers suggest or would the S10 frame be sturdier? Any insights would be appreciated.

I would stick with the boxed factory frame..unless its a mess..I'm putting a flatout c4 front under mine and its designed to be used with the factory frame..there are several full vett suspension swaps on here..

thanks, that's the direction I'm leaning. I guess I need to confirm that the original frame is straight. Once I get it together I will add some cross bracing to beef it up.

Iwill follow this build

On my '55.2 I am using C4 IFS with the FlatOut cross member. We boxed the front portion of the frame only. In the rear I used a conventional live axle flipped on top of the leaf springs. This will result in dramatically olowering my truck and giving me a much better ride. But now I wish I'd have used the IRS too. Oh well. Depending how and how much I end up driving my truck this is an future modification waiting to happen.
