I had a 383 in it that pushed the car 12.25-12.30 with no tire spin at all. Now I have a 470 that is not real crazy it made 644hp/603tq. I did change the vert from a 3800 to a 4500 but the rest is the same. My best is 11.01 but my trap speed 122-124 so you see I'm leaving a lot on the table. So do you think the E.T. streets would be a better tire or should I spend the money on the suspension

Nothing trick, just the basic Cal-Trac rear suspension. What do you have for suspension?

If you have Cal-Trac bars, call Calvert Racing and get a pair of their monoleaf springs and Rancho shocks.

I have been 1.29 60's footbraking and normally click of 1.32's in good weather all day with no problem.

I had a 1.49 60' with the 275 D/R's this weekend and my best on slicks was a 1.45 so these get my vote Last edited by 10secGTX; 09/21/09 05:16 PM.

Duster that has gone 1:43 60. ft times on 315x60x15 M/T ET Street Radials at 10:34 and 128.6 MPH, no power adders It is a ladder bar car with coil overs and a track bar, I also have a set of 13:50x30x15 ET Street bias ply tires on the same size rims as the radials. The radials will run quicker and faster on a good track versus the bias ply tires, the bias ply tires will drive easier on a bad track and not spin at the top of first gear like the radials will on a bad track I have found that after driving the radails on the street, the first pass, no matter what kind of burn out I do , will spin bad, the second pass will hook a lot better no matter on the burn out procedures I do run between 17.5 lbs and 22 lbs in the radails and 9.5 to 11.0 lbs on the bias plys on ten inch wide rims. IHTHs BTW, if you run the air pressure to low in the radials they will not hook Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I do a fair amount of street driving on them too though.

When the tread goes there goes the 60 foot? Myself, and everyone else I know running them, have the opposite happen to us. The tires get better when the tread is gone. They hook great until the chords start showing, then I replace them. Still hook with the chords showing actually. This is the case with the M/T radials anyway.

The bias ply tires push the car forward even if they spin a little, while the radials really tend to loose the traction completely if they start to spin. Plynouth VIP '67 TT IC EFI

I say that I hook good at around 15 cold....just that I've never tried it lower than that because it seems OK at that pressure. So many others on here running up at 18 and 20#'s that it almost made no sense to go lower.....then sit back and complain about the crappy tires! I'm wondering if there's a little more 60' left in it if I try going down a tad more? It hooked hard at Pinks in Seattle, and seems good at our tracks here...but there's always that search for that "little bit more". One thing for sure though....I'll never run a bias slick again...the radials run the track so straight compared to a slick at 11#'s. Next year I guess.....
