I'm going to be the wheel man on a '94 Rayburn chassis. I guess it has the '98 updates on the front end (it has the "silver" front susp.) and the rear has the long swingarms. My main question is; is the spring and shock package much different on this car than the newer (14" swingarms) cars?

I can help ya with this one, your cars almost identical to one I ran a few years ago.
58%rear
55%left & cross
200lbs of wedge to start and you may need as much as 240 or so if it get really slick
-4 degree pinion angle/ 1/4in preload---if you use a 5th arm
550lf 450/500rf
300lr 225rr
2 1/4in lf rh
2 3/8in rf rh
4 1/4in rr rh
start with 4in of J bar rake
(I like a straight bar alittle more but this is driver preference)

Rayburns (if using the swing arms) are momentum cars and they need to be drove more aggressively than a 4 link, their especially good on rutted up tracks, and normally their better on bigger tracks.

My advise would be to use standard valving to start:
75's on the front
94's on the rear
7300 on the 5th arm
and then maybe after you've gotten used to it mess around with rf and/or lr split valves.

Thanks, Go 24... This car has a pull bar on it instead of the 5th arm. I really don't know anything about the swing-arm set-up on these cars. Does it rear-steer very much or roll over onto the right? I pulled the set-up off of the Rayburn web site... Of course, it was for a newer car with the short arms, but it was close to what you are giving me.

Thanks again!

And... I just can't get over the amount of cross weight you are talking about! I know you are not nuts, because Rayburn's site says the same thing! Is that common for all Late Models? In my 2003 DirtWorks Mod, I'm only running 52% MAX.

Thanks again,

Greggie

No problem, I'm not real "up" on the pullbars but if you need questions answered on that I could find out--good friend of mine runs a 1999 with that setup. As far as the swing arms go I ran the rr in the upper hole, the lr level, and just left them there. The car will not have any roll steer and will not roll over near as much as a 4-link.....that's why their so good on big momentum tracks, Eldora for instance.
I don't think I ever ran less than 200lbs of wedge, I usually started with that and then "jacked" in a couple 2/3 rounds if the track slicked off. Nothing like our new 4 link were we start with 80 or so lbs 52-53%.
I liked mine with alot of stagger, 5 to 5.5 in and I also ran the short/straight panhard bar---fairly flat to start and then up the angle as it slicks off.
All in all I really liked my Rayburn and would have no qualms about driving one again. You have to take CJ with a grain of salt but pay attention, the guy has forgotten more about racin' than most of us will ever know and if he tells you to "just go to the hotdog stand" or "just drive the darn car and forget about it" don't take offense! LOL good luck

Thanks again, guys... Randy, I'll get with Art sometime, probably at the auction, and pick his brain a little bit, for sure.
