best drag radial for a heavy 3700 pound chevelle

im looking at drag radials for my Chevelle and currently run a 28x10.5 stiff wall slick.I run right at 6.4s in the 1/8th with my car.It weighs 3700 with me in it.The car is a bbc with turbo at 9psi.The engine is a stock 1974 bbc with a summit 500 lift cam on a 114 center.The trans is a th400 with brake and ptc converter that stalls at 3700rpm with ford 9 inch 35spline and 3.50 gear.Im looking at drag radials and was wanting opinions on the best drag radial for a car like mine.I also run the moroso trick front and rear springs with 90/10s and racing rear shock and bmr anti rollbar.Would love to hear opinions on your favorite drag radial and what you feel works the best.Also is ther any that can take the place of my current slicks as far as times ..thanks in advance

Re: best drag radial for a heavy 3700 pound chevelle

Bracket radial i hear is good. I loved the 275 pro radial tho. But may want a real shock instead of 90/10s to really take advantage of that combo

Re: best drag radial for a heavy 3700 pound chevelle

I made the leap last year, ran a 28x9 MT stiff wall for 30yrs. I ran consistent mid 1.40 60`s and the car was not pleasant on the big end.
The first pass with a 28x9 MT PBR the car went 1.35 60 and was much better on the big end. I have double adjustables on both ends and did need to change the shock settings quite a bit when going to the radial. What is the "best" that is a matter of opinion but I will say there are a lot of good options and you will need to tune the suspension to whatever tire you decide on.

Re: best drag radial for a heavy 3700 pound chevelle

hopefully you can see the picture. these are my 28x10.5 Pro Bracket Radials. over 100 passes, cords showing, went 1.31 sixty foot and 8.54 at 161mph. it's the best radial i've used so far.

low number of passes is due to my propensity for doing excessively long burnouts.

And my 29.5/10.5 PBRs are well over 200 passes old!!
I’m getting a little worried now lol

Re: best drag radial for a heavy 3700 pound chevelle

M/T 3355 on my '66. Best was a 1.301 60' with a 3.73 gear.
If they chatter they can break stuff. Ask my gopro mount.
By comparison I've run 1.306 with the 3055s slick and a 4.11gear.

I have a manual trans ; a stock LS1 T56 from a 2000 Camaro and the two drag radials I'm looking at are what Dan recommends, the 10.5" wide M/T 3355 or the 9" wide M/T 3354, which is identical only narrower.

I am afraid of "hooking too well" and damaging the trans. The rear is bulletproof (Strange S60).

Should I stay away from the 10.5" wide slick ? The clutch is a single disc diaphragm centerforce type, so it should not be "too grabby."

The engine is a small-cammed (224/234) wolfie 489. Probably 525 hp.

I still think for a stick car, I would stay with a bias ply tire. They are more forgiving and will not chatter. they will spin and recover.

Re: best drag radial for a heavy 3700 pound chevelle

There are a couple different ways to make a stick compatible with a radial, they involve softening the hit of the clutch and letting the radials dead hook. When the tire dead hooks there won't be much difference between the two tires mentioned, you will be able to make the choice based on aesthetics.

I am installing a clutch tamer.

Is that what you are referring to ?

I think I'd go with a bias ply on a stick car. Only thing you might sacrifice might be some slight mph.

If you are installing a 'tamer, either one of the radials will work.
