carb choice and slick size

LXguy said
Hey:

I run a 670 street avenger as my cruise/ light strip carburetor.

Its plenty for your motor. My car has run 11s in the quarter with that carb. It is great for the street also. Very responsive, quick to start. My combo needed a 35 squirter and up a couple of jet sizes for peak performance.

I have an approximately 3500 stall converter and it works fine with this carb.

I prefer slicks to drag radials for consistency. Drag radials are capable of the same 60' times as slicks *but* they are much fussier about track surface. Also, they are harder on driveline parts than a slick.

Terre Haute is a great track. It hooks well so you might be able to get a drag radial to work. On my 71 Dart I run either a MT 255/60/15 or a Hoosier 26*8.5 stiffwall slick. I run a 15*8 wheel with 5.5 backspace (I run Pro Stars, but anything should work). I do have to run a 3/8 spacer for peace of mind.

My car has been 1.5 60' lots of times.

If you end up needing a spacer, let me know and I can show you which to get.

Good luck!

Thanks for all the info but I just home after being gone all day. I already bought the carb it was off a running 73 360 duster so I knew it was good. Its a 750 vacuum secondaries . The car I bought hadnt run in a long time I guess and I bolted it on and checked everything out and the car fired right up and smoked for a bit because of old fuel in fuel cell. Once the old fuel was out I put new 93 octane in and the car runs and sounds awesome. Idles great for the cam it has .484 purple shaft with headers and flowmasters that drop just in front of rear axle. When I rev it , it doesnt hesitate at all so I think it will be great. Im kinda interested in what the car will run, only downside is the 3.23 gears I would like 3.91 but dont have the cash right now. The car has no interior right now besides a drag seat and dash. Im gonna keep it a street strip car. It has coil overs and a four link also. Bad thing is that it has the small bolt pattern axles all the way around and Im not changing it yet because I wanna be able to race come . spring. Since I dont have leaf springs I wander what size slick I can go with with what backspace. I wanna keep the height down so I dont lose what little gear i have. I seen some 26x8x14 slicks. So what do ya think. Thanks Clint... Oh I hope it will run at least 8.5 to 8.9 1/8 mile.. I think it should.
