Jim Hale's current car is a 383 small valve, small carb combination - 1966 Belvedere Station Wagon.
Can't the side bars be welded to a 6x6 bolted plate as well as the other braces? What if no sub frame connectors, for the bar braces to "weld" to? Wording in rule book is contradictive somewhat, one can "bolt" in the roll bar but the braces have to welded to subframe, page 212-D & 205-4:10. Most of this was written 40-50 years ago (when the fastest Super Stocker ran in the 11s or high 10s) ,maybe time for clarification or update.

The welding to subframe connectors is optional if you have a rollbar instead of a cage. Look at the rule book for the minimum required installation.

now that this thread has been completely hijacked, time to add another question. I am going the 318 route now. What are the best years for 318 blocks as far as deck and wall thickness?

I tried to stay on point for you. Just find anything as early as you can 66-72 dates are best. Most of these should be nearly free. For years I paid scrap value for 273 engines.

Paul, you were directly on Point, it was the roll bar and other discussions that went into another direction. I have a couple of 273 blocks here at my place if you want them

You did bring up the roll bar did you not?

Pat Cvengros called me today and told me the new Diamond 318 piston, #80077, was a "True flat top" and "no valve notches" according to Pat. Not sure what happened, but that is disappointing.

I believe I originally brought up the roll bar issue since I was reluctant to put one in my 340 Barracuda. I guess it could always be cut out.

why did you decide to sell the 318?
