Do radial slicks hook better in the heat than bias?

The avatar has 28x10.5W bias slicks. More width than a low 11 sec car should need. Maybe it would be fine with less. The car has split-mono CalTracs as well. 5000 stall converter with a 4.10 axle. Guestimated weight of 3350 at the line.

I ran my radial street tires once at the track - P295/55R15 ET Street S/S. Knocked em off once and they hooked once. 50% hook rate - and saw 7500 rpm on the tach (I shift at 6150-6200-ish). I was done trying them!

So when it came time for new shoes last year, I thought why go to a radial and risk spinning/track prep/whatever. I wanted to try radials but if I spent big coin to buy them and they didn't work and then had to go buy a bias set, well that might be hard on the racing budget and my ears so to speak. My wife reminds me all the time that it's not about how fast you go but only about consistency. So I just bought the identical M/T 28x10.5W bias slicks and called it good.
