I'm picking up this project after letting it sit when I went off and started racing Porsche's.So I'm changing direction on the project. Like I never heard that before. I tired of play in a class that I'm down 125 - 175 HP from other Porsche like GT3's with tons of camber. So we come to this project that has been covered with 3 car covers and a folded up large screen TV box to protect the new paint that has not been color sanded yet.

So I have this started project that I already bought ton of parts for so I say why not. Yes it's a big car and if I started again I would build a early 60's A body. But I have the and I see cars this size running CAM so why not. I'm driving a fat azz car already so what the hell.

I bought a Hughes 6 pak strocker kit with a Indy dual plane intake. And I also bought Wilwood Dynalites for front and back with all hardware. Yearone had a very large order.

I installed Firm Feels braces for the LCA and the K frame. When I started to weld up the K frame the HF welder broke so new Milermatic 215. Dam my welding got better with that welder. I also bought US Car Lower radiator support and inner fender support. I will build the front torque box plate and build one for behind the rear spring shackle. I will also tie the frame connector to the inner seat mount.

I did add Classic Air years ago before I but the project to the side. The heater box is lighter BUT with the 134 compressor and other parts it's heavier but at my old age I want air. Years ago I 7/8 Hooker comps and only thin carpet for weight savings and I melted a pair of tennis shoes so I installed 2 layers of insulation in the front. I also found year ago a 4 door Satellite that was a factory air car so I have all duct work and dash vents with controls. Now that was a nice score.
When I was building the car for a hot street car I had a bunch of C body power window mechanisms. All you have to to do to make B body power windows from that is take the b body window arm off the half moon gear and put it on the C body half moon gear and it just bolts in place. I have to change over the drivers side so when I do that I will take some pics. The pass side is done and in. I may pull it so I can lighten them up. I need to pull more weight from this porker. I'm working on that now.

There is a guy who's been running a 4 door Satellite/Belvedeer for awhile. He calls it a 'Taxi'. Painted sorta like a taxi. Does great at the autocross at MATS even with 4 people in it. Last I knew he was selling it and maybe getting a different car. I never can remember his name, but kinda goes by 'Monsour' something name here on Moparts. You can get in touch with him thru Hotchkis as he runs their suspension equipment.

I don't know about that as I only had 1 mopar that the lady's would walk up and say nice car. That was a 66 Dodge Monaco 500 that was the yellow with white interior. But the high priced that's all black I get that all the time. But the GTX is way cool

Sweet project!! I'd love to build something like what you're doing. Any concerns about cowl shake with stickier tires and stiff suspension underneath it? Going to put in a rollcage or 6 point rollbar at all?

I'm looking at a 4 point roll bar. I need that for a harness and race seats. I'm also tie the subframe connectors to the inner seat mount and the drive shaft loop. Subframe I already have subframe connectors installed but I will mod with this in mind.with The US Car inner fender and lower radiator support and a custom front torque box. I think that the car should be tighter. I also welded up the K member and installed the firm feel steering supports.

Is your car the one that I see with the numbers 383 on the door? That is a good looking car. I would love to chat about your setup so I can get this thing close. One would be what did you do to enough negative camber. I'm looking to get between -3 to -4. I haven't replaced the upper A arm cam bolts yet but I have been looking.

You can add thin washers between the steering knuckle/spindle and the lower ball joint to get 2 degrees of additional NEG camber.

eek
I believe he means caster. That much camber of on a wide tire serves little positive purpose normally.

I meant camber. If I can get -4 I can set it where I need it. -3 sounds like a good starting point with 0 toe. It may need about 1/8 toe out but we will see how the car is works. My Porsche I can only get -1.2 front and I have -1.8 in the back with 0 toe. I would love -3 on it but I can't run camber plates in Street class so that is all I can get from the adjustment.

Yes caster needs to be fixed on Mopars I'm not used to that as you leave Porsche at stock settings. Yes -3 camber is a ton and I wouldn't run over -1.5 on the street but this is a class car and very limited street use. Now lets see about large fronts and large amounts of negative camber. ASP and SSP Porsches with 285 18 fronts running -3 to -3.5 with Hoosers. Mike won the Dixie tour in his Fox body with 275 18 f and 335 18 Rival S with over -3 camber. I may only run -2 or -2.5 and the car maybe happy there but I will be going for the year end trophy. So I need to see how close I can get to 1.5g but I need to hit at least 1.3g. And that is a ton in a B body. I want the adjustment in case it's needed. I do run the complete season plus at least 1 champ Tour. Hey it's all good.
