Another fine job by RJ Profab 
Car looks awesome!! I've got a few questions:
Is that rollbar from a kit (S&W race cars maybe) or was it custom built?
What size wheels & slicks? What backspacing?

The rollbar was custom made by RJ Profab to meet NHRA 8.50 cert
and the wheels are 15x10 w 5"1/2 back space slicks are 29.5x10.5x15

Thank you for the quick reply. Is the rear stock width? I had some 15"x10" wheel vintiques rallys & M/T - L60-15's on my 61 about 15 years ago. I remember that I had to run 6" of BS for them to fit. That was with everything stock so the rear wasn't centered. I've got 15"x8" Pro Stars with 4.5" BS & M/T 28/10.5-15's now and looking to get back to a 10" rim with the same size slick. I know I'll have to measure my own car to see exactly what I need, but it's still nice to see what works for others.
The 9” rear end was built to the stock width but I also have it back 1” more then the stock rear end, I did have to massage the inner fender wells though
I just realized that this whole build has only been about 8 months since the car was posted for sale!!! WOW..... I'll be happy if I can get mine to this point in my lifetime. Amazing work.
How did you go about getting the rearend 1" back? I saw that your front upper & lower mounts are in the stock positions. Did you just use longer upper & lower control arms?
Roll bar looks great Brian...I love it with the stock Biscayne interior...
Thanks,
Can you please post some pics of the rear suspension on the car? I know it's been discussed before, but I don't remember....are there any downsides to using a straight upper control arm? My UMI adjustable uppers are curved like stock arms. They are mounted to the housing in the stock location, but the front mounts have adjustment holes to change instant center. I might be better off to build some rod-ended straight uppers and lowers to move it back like yours.
Thank you. I see you still use stock LCA's (Boxed I'd bet).....did you lengthen the actual arms themselves or did you relocate the bracket to set it back an inch? I've got Metco Aluminum LCA's bolted to the stock front frame brackets, but I really like the way you reinforced yours. Maybe I could do something similar there and move them back 1" at the same time....keeping my same control arms.
Also, I see an nice Anti-Roll Bar hiding up there. I have been considering one of those to level up the launch. I can't use airbags because I've switched to coil-overs mounted off a custom bolt-in crossmember I designed. I haven't ran it since....so not sure if it still twists as much as it use to. On second look....I don't know if I could squeeze that anti roll bar in with the coil over crossmember. Looks like it would be close.
Hope I'm not cluttering your thread up to much with my questions. I will start a new one if that's better.

Yes i still have the stock LCA all boxed in with graphite bushing and were lengthened under the spring mount. The anti-roll bar is one of the best things you can do
Any updates? Is the 61 going to be in Thompson?
My block is supposed to go the machine shop tomorrow @ lunch for cleaning, cam bearings, and a light cylinder hone. Unfortunately I have to send the crank to a different machine shop that's in the next town so I don't know when I'll have a chance to take it over.

Another milestone Brian............lookin good...........
It's great to see an update. I'm enjoying following this and the "Homewrecker" thread. If you know of any other drag build threads on here I would like to know about them.
I'm waiting to get my block and crank back from the machine shop(s) too. I'm only shooting for mid 6's in the 1/8th....mid 10's in the quarter so not nearly as quick as yours. Should be a little easier with a rat motor too. Maybe one day I can build a nice 409 for it. I don't even know what a 409 block to use for a core is worth these days.
