I saw the P1800 build on here on Lateral-g and I got inspired. I am in the middle of a 1969 Camaro build, and my next car will be a P1800. I found a 1965 P1800S in the woods in Willits, CA, a complete car with documents that go back to when it was imported into Canada from Sweeden, maintenance records from the 60's to the late 80's from all the owners up until the current owner who drove it until 1990 then parked it. Major rust in some spots on the floor pan, rockers and wheel openings, almost none in others and most of the rest of the car, I need to start tearing into the car to see whether the floor is salvageable, everything else is mostly rust free and solid (the car spent its first years in the rust belt in Canada), but there is some minor body damage to deal with too.
I've been checking out a bunch of things to do with the car. If the car is rust free and straight, check out this thread on CHANGLING. You can also search Google on "P1800" and "LS1" and there are other threads on that build.

Robert has put together a suspension kit for P1800's and Amazon's, looks slick, and mostly a bolt up application. Front and Rear kit.

I went to the Good Guys event this summer in Pleasanton, CA and talked to the guys at Art Morrison, and they have built a G-Max replacement frame for a customer already. Send them an email and they can send you info on the P1800 frame they put together for a customer already. Major floor sheet metal surgery on that car if you use that set up for sure, but there are some REALLY-REALLY-REALLY SICK/AWESOME/RADICAL rides based on the G-Max (I'm still blown away by the 1954 Vette with a G-max frame). Well worth an email and a phone call.

From what I've been able to figure out, the wheel base is pretty narrow (96 inches) and the track width is pretty narrow too (59 to 63, depending on how much tire rub the owner is willing to tolerate!!). Kind of hard to use Vette geometry all around, unless you are willing to stretch the car, move the wheel openings and/or flare the fenders, and then trim the torque tube to fit the P1800 wheel base. It has been done, and it is a TON of fabrication. From what I've seen the recommended hub-to-hub track width from most custom shops would recommend a 53 to 55 inch range, and if you plan to use a C5/C vette front suspension, you might have some pretty narrow frame rails. DSE just released a narrower front frame. Don't know much about it, but it is a DSE product, and make some good stuff.

I've been hitting the Car shows and photographing other cars that have been built that are the same size and proportion. I found an Austin-Healey (??) of about the same size that had 2 to 3 inch flares on all four corners, and the side pipes that the builder used really brought the car back into proportion, as the car would have looked like a race car (and kinda funny) without the side pipes.
Have fun with the build!! And keep posting pics!! Lots of Pics!!
