Not sure lol cant remember, its a eddy thunder series.That's an AVS, Air Valve Secondary. Are you having any fuel percolation troubles with it?What intake under it?
I guess my car just has a sweet spot launch at 4k. This is on the street though on fairly new asphalt with a 4 speed. Running about 28-30 psi. Running a pinion snubber with factory springs out of a duster and sub frame connectors. I guess if i launch at 6k i wouldnt get any traction lol
Really wasnt much choice on tires, lets see cooper cobras or bfg ta, i went with the bfg.Don't worry the Coopers are no better
Now i come to think of it if i put drag radials on it i may start breaking stuff. Already had to put a torque strap on the engine Yeah my car on day 1, hit the road with a Schumacher strap.
and have bent a pinion subber bracket from it peing out too far over the pinion yoke I have a beat up floor from that snubber

I love 71 Demons, I think they are the most muscular looking A-bodies of all time.
I have never been able to figure out what I was thinking,when back in the early 80s, I parted my beater out. I shoulda hot-rodded it, it wasn't that bad yet, and would still go for mucho dinero today. It was just a little too beat up for me at the time. Boy if I only had it today, with what I know now.But at the time, the babies were arriving, and that took precedence.
I still have the powertrain from it. The teener was my winter engine 5 winters in a row, then got installed into my sons 84D100, where it hauled *** for about 8 more years. Now it sits, waiting for it's new home.The tranny in it was the best-shifting factory 904 I ever came across, so I cloned it two more times. One of those clones made it into the S with the winter engine, and eventually into the D100 also. The original is still on the shelf.
Hyup, I love those 71s. Congratulations on owning a fine piece of history.
