engine choice?

2016 Rulebook, "Unibody cars with stock floor and firewall (wheeltubs
permitted) may attach roll bar with 6-inch x 6-inch x .125-inch
steel plates on top and bottom of floor bolted together with at
least four 3/8-inch bolts and nuts, or weld main hoop to rocker sill
area with .125-inch reinforcing plates, with plates welded
completely. Also, the roll bar may be welded to frame connectors
that are fully welded in place and are 1 5/8 inches x .118-inch
MS or .083-inch CM round and/or 2 inch x 2 inch x .058 MS or
CM rectangular."

Just another thing I've learned today.

I believe that you will find, however, that all the braces and side bar must be welded to the car. I ran into that way back in 1980.


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.

That's what we're taking about, minuim roll bar, not a cage

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?
