In a 425 hp engine will I get some wheel spin out of the hole or will they hook within a few feet. - without heating them!

Without heating them....hmmm....you probably won't get a dead hook, but they should hook within 10-20 feet.

When I was around 425 HP and 435 TQ I still had to heat them at the track. Tried it a few time without heat and it didn't work.

What size engine? Is it a high torque 383+ or a 350? What stall, gear and rear suspension aid do you have?

Very similar to your build.

I have a pair of 275 BFG drag radials, If I don't heat them, all they do is spin. They are rock hard when cold! But if I do a Funny Car style burn-out (smoke them to no end) they dead hook and cause a bog of the line! I run a 3.90 gear and a 3000 converter.

I was going to do a search on drag radials. Timely post.
I took my new 406 to the track Saturday with the street tires. I spun through first and then again in second before I was planted. 60 foot in 2.5 area. As a result best time was 14.0, the MPH was consistantly at 104 MPH. My last time on street tires for sure.
I saw both BFG drag radials and some Mickey Thompsons being used. Both seemed to hook ok on various cars. All of the people did some burnout before their runs.

Especially with a 4 speed and 4.11 gears(and of course your motor), launches will be abusive(unless you intentionally dog it) and I dont see much of a way to get around heating the tires a bit if you want it to hook. One it does hook, I sure hope the rest of the chassis can take that kind of motor with a stick tranny.

I am installing subframe connectors tis weekend. The motor will go in in a week or so. I do not know what to expect from this new build. My prior motor was a 355 with the AFR's. Should be interesting. I am going to purchase the BFG drag radials for this build. they should be the right tire for the car - on the street I can get some wheel spin and then when they heat up they should give better traction than a regular BFG radial. Thats my thought anyway.

The Mickey T ET Radials hook REAL well. Better than the BFG's. They even hook on the street. I am very impressed with them. When you do smoke them, they make one heck of a cloud too. I don't know what the tread life is like on them yet.

I agree with camaroman completely. If you haven't bought the tires yet, go M/T. I have officially made the switch after 5 years on the BFGs. At the track the Mickey's require MUCH less burnout to get to work and hopefully that translates into more passes on them.

I guess my question is will these tires be more sticky than the original white lettered BFG tire?

Yes, there are a lot of tires out there that are more sticky than regular T/A radials. Maybe if you tell us what the plan for the car is that will help. If you plan to go to the track then I would go with Mickey T's if you never plan on seeing the track then it doesn't matter all that much. For strictly street driving I don't know if I would spend the money on a "drag" tire. By design drag tires are soft and are not going to last as long as "street" tires. You might want to look at Goodyear Eagles or something along those lines, they will have more grip than BFG T/A's. No standard street radial is going to hook on the street (or at the track for that matter).

Before I install my new engine I need to change my tires. It is a street driven weekend warrior. I do maybe 3k miles/year. Since I have more power than my 355 I would like a tire that will hook up more than a regular radial when I jump on it. I am not concerned about tire wear since I only put 3k per year on it but I would like a little better traction than a regular radial considering my engine.

If you are not worried about tire life then a drag radial will do exactly what you want. I can tell you that the Mickey T Radials hook on the street without doing a burn out. Either the BFG or micket T drag radials should give you what you want.

What tire pressure are you using at the track?

What tire pressure are you using at the track?

I run 18lbs.

I think your selling that motor short on HP, unless your guessing at rear wheel HP?
I would recommend a MT DragRadial at the least. BFG DR would be second if you want to stay with a radial.Otherwise MT ET streets.

another vote for MT drag radials, they are excellent tires. just feel a bfg and a MT and you'll see the difference. i'm going to put a set of the MT's on this summer, to replace my bfg's.
just look at the drag classes that require a radial, and i guarantee you'll see the MT probably 10 to 1 vs the bfg. they just flat work at the track. i have yet to run a set, but a couple of the guys we race with (that run in the radial class) have gone 8's on them already, and 2 or 3 more are in the low 9's. and they do seem to require considerably less heat to work.
that said though, my bfg's hook great at the track, but there is no way in hell to hook hard on the street, they are better than the standard radial hockey pucks, but don't expect a good hard launch with either. i am confident the MT would be better however.
good luck :thumbsup:

I am only guessing on the Horspower. I do not know what to expect of this engine.

The BFG drag radials will be my regular cruising tire, not for the track.
