If you guys don't notch the frame and pack the rear panels, I'll give that thing 1 race before it's toast. Maybe even 1/2 a race.
Your car will turn into a plow in 1 hit if that frame bends the wrong way.
Jack the front end way up with some Ford truck springs, and pack the rear by smashing it into the olds 98 in that field a few times. See how your notches are turning out. Also, chain the rear frame arches together so they don't bow out and lock up your rear wheels.
Keep us posted on the rules out by you. I bet Idaho is pretty light on hitting you with the book. Sounds like a blast. I demo'd my 84 delta in 2001...threw a rod through the pan & snapped an axle. What a marshmallow
307&7.5'' rear is a garbage Heat setup.
