View Full Version : What size slicks?
I have a '66 Chevy II, tubbed in the rear with a 4-link. 3200 Pounds.
Blown SBC, 630 HP, 605 TQ, TH-400
I have a set of 15" x 15" rims. Plenty of room to run 33"x16"s.
Question is, How wide is wide enough? Should I run 14's, 14.5's, 15's? I see people hooking with 10.5's with much more power. I would like to save money and use the rims I have, but how much is overboard?
Is height any more a question than roll out and gear ratio?
I assume D-5 compound or equivelent.
Thanks again. Should have track pics within a month. Long time comin!

a 32x14 should do you just fine. What rear gear?
3.50's right now. Waiting to see the first 1/4 mile results before I change them.

14x32's would work, but you mentioned that you wanted to run 15x15 rims. So your probably going to have to run a 16x33. Your tire needs to be an inch wider than your rim width.
Any thoughts on the Hoosier Quick TIme Pro DOT tires? They make the same size as my street tires(31-18-15), just curious if they will hook on the track.

3.50's ??? Not a good starting point with a 33 tire. Just my opinion. Dave

x2 456 or even 488 would be my guess with a 33 inch tall tire

Agreed. 3.50's are a waste of time. At 3200 lbs, you'll need a 5.13 or better with a 33" tire........my Vette with a 575-600hp sbc @2050lbs and a 4.88 gear turned about 7000 rpm at the stripe and 7700 on nitrous with a 33x16

They will not hook like a set of slicks. Unless I was running a class that demanded DOT tires, I would run slicks at the track.
Thanks guys. I had 4:86's with a spool and put the 3:50's with a locker in for the street. Now I miss the track and plan on building a second third member with the spool and I don't know what gears. I redline at 6300 rpm and thought 4:86 might be a little steep for the 1/4 mile.
Still not decided on what size slicks to run...
I'll have money next week for them and the track soon after!

4:56 with 16 x 33 slicks is what I would run. JMO!

I Agree 4.56 and 16 x 33 should work for you. I run 33.5 x 16 hoosiers with a 4.86 gear. With the little motor is ran 11.21 @ 119 and I went through at 6400. It just depends on how fast your car is. You need to have a good idea of what it will run before you can figure it out for sure...

I ran 3.73 gears in my 69 Camaro with Hoosier 28 x 14.5 x 15. (Had a 13.1 section width) Worked well on 10 inch rims which was the recommended size. Used to run 4:11s but wanted to drop the far end revs some. Had a TH400 and transbrake.
That was with 1100hp 572ci with 200hp nos. Hooked up no probs, ran 9.3 sec quarters. Weighed 3200 lbs.

Yes, but he said he wanted to use a set of 15x15 rims, and has plenty of room. That why 16x33's.
