I don't know about that. Slight bog, no spin, typical rear coil spring twisted wheelie, I'd say that thing is "dialed in" ! LOVE IT!!

Alright, having been through several 409 powered cars, the logical questions come to mind: 1. What did you do about the rear suspension with the single upper trailing arm that liked to tear loose from the frame at the front?
2. What rear axle assembly is in the car? A 12 bolt comes to mind here. 3. What gear ratio?
4.How about the drive shaft?
5. What is the total weight of this car with driver?
6.How much fun is it to drive? Looks like a real hoot.
7. What is the quickest and fastest time to date?

Best wishes on this project. Looks like a lot of fun.

I am not sure. It looks like TONS O' FUN to me.

I've seen that car before.Looks like he got some hp off..so 170 x 20 = 3400 + 170 =3570.
If Denny Ford can get his 62 409 down the track ,this one should be fairly safe

Seems to be having fun.
Looks like it runs under the index. That's all you need in U/Stock ;-)
I can think of better cars for that class LOL

Former U/Stock record holder ;-)

64 Impala SS (maybe) 283 2bbl NHRA 170 hp. Minimum weight w/driver in U/S is 3570. (Class Racer Info)
Something different. I like it.

Former U/S record holder also! Sorry Yac, I had to get that in.

Yeah, I was writing the line about better cars, and thinking what would be smaller, lighter etc. Thought of the Fox and then I actually had one. We ran V normally but we wanted to take advantage of the altitude correction at Tucson, with the turbo , so we did the U deal there.
Anyway ...Sounds like we may have a reunion going here..How about Paul Wong? The Witch Doctor? Koski?....
