I think what Tony means you use the roll bar as a way to strengthen frame. I have lower crossbraces to that crossmember that tends to pull out. I also replaced rubber body bushings with solids.

That's what I was referring to. Roll cage to tie together and prevent frame twist, then anti roll bar to prevent suspension twist. Obviously solid bushings to help stop suspension movement (and body bushings too, as you stated). I also prefer adjustable shocks for fine tuning. Some of this is referring to coil spring cars in general, (my Mustangs), while some of it is from previous A bodies, I have owned. (Monte Carlo, several Chevelles). These are my choices, others may have a different opinion.

Yeah, if I understand the general rules I looked at online, it appears that all cars must have at least a 5-point roll bar which includes a driver side bar. So, I assume that a good 6-point will strengthen the body / frame enuff for 11 or 12 sec Stocker duty.

Found this info in section 20, page 20-21 under "4:10 Roll Bar" There is an illustration on page 21.

You should reread. All cars are not required to have a rollbar. It is ET specific.

It is CLASS specific. N/S and lower do not need a rollbar.

I guess we are both right. Let an N/Stocker run quicker than 11.49 and it too will be getting a rollbar,(and a HP Factor), LOL. But you are correct, as it stands, CLASS specific in Stock.

[Dave Ribeiro]

Billy , is exactly right about N/S - N/SA & Higher ( O,P, etc. ) That's another advantage for your build ...

Nope.. Will get hp.. but no roll bar ..
Maybe down the road...but NHRA rules trump local track bracket rules at a sanctioned event.

[Tony Corley]

Yep, you are right.

Another thing I did was go to Stock Eliminator races, being either Divisional, National or Stock/Super Stock combo event (Like ASRA around here) and look for cars running your body style and/pr combo. If the owner don't mind just look underneath or at car. That's how I got ideas to work I needed to do on frame. Sam Murray's stick shift Olds 442 is a good example for me. Also if you want to golf hang out with golfers, I always wanted to build and race a Stocker so I hung out with Class racers. Jimi Vignogna and his dad Lou helped me tremendously. Pate Henneberry, Joe Huestis and Clem Lachance others. Lou V was really happy with the power my 396-325 HP BBC was making as I was running higher MPH every week. He said if I go over 115 MPH he will sell all his Chrysler stuff and run Chevies.Should have seen his face when the following week I showed him a ET slip reading 117.11 MPH LOL Plus the help and support from Johnny Williams -RIP Coolest people in the world!
I personally looking forward being back out there this year Lord willing.
