Im just curious how a drag radial will stack up to a slick on a car that sixties in the 1.48-1.50 range?
I know. I meant numerically "kick up" the ratio. I want the engine to run at a higher RPM.(at the track) The engine I have would would be happier with either more gear or shorter tires. Shorter tires will be the simpler way to achieve my goal. Since I`ll still retain the same cruise RPM when I bolt the street tires back on. By the way I`m still curious as to what kind of times you ran with the Blown Pro street car ?
Bryon, there is a lot of good advise here. Here is a few things to think about. What stall are you going to run? What cam are you going to run? What carb are you going to run? What heads are you going to run? What gear ratio are you going to run? How many ponys do you HONESTLY think you'll going to have? Will you use NOS? Is this a drag only car or will it see street time? I've seen a 28X15x10.5 (that the biggest that will fit on our cars without mods) just KILL a car's time. The car left the line and died because the motor couldn't handle that much tire. The same guy listened to all the old timer and came back the next week with a 26X15X8.5 and improved his time by almost a full second! Shorter tire lower gear ratio! A 28X15x10.5 will handle a lot of ponys most people have to compensate for a lack of track and put HUGH tires on their car. If you have a hooken track then a smaller tire will do. Something else to think about, you can have all the ponys in the world but if you can't get them to the ground you are just wasting your time. Having a good traction system is very important. Springs, traction bars and shocks play a big roll in how you put your ponys to the ground. Just food for you to think about. As always just my .02 P.S. 1.37 sixty on a 28X15X9 MT Drag! Man I miss my 10.5's Bossmav
Could have changed rear gears and/or converter & fixed that problem....thats what I had to do. Glad I did too...paid for itself many times over.
28 inch slicks kill my car. Just not matched to the rest of my combo. Despite ,y crappy worn out suspension I can usally hook at a good track with 23560r15 MT drag radials. thay are like 26 inch in diameter
Street car, and the guy was still wanting to keep it that way. 3:50 ratio and a nice 302 but not enough for 28X10.5 Changing the tire size is a lot easier (and most times cheaper) then the stall or center section. I guess it's just what you want to do with your car. I'm glad it work for you, sounds like a good move. Bossmav
No offense but i want to see a 10.5 tire under a mav without cutting. I run 28/9 on a 8.5 wheel and you cant get your finger between the leaf spring and tire to the inside or the lip on the outside. I even tried a 9 on a 10inch wheel and it wont go.
Lots of information here. I'm just laying back and reading. Right now as far as the engine/trans combo goes. I'm looking at a Dart block 9.2" with an aluminum cleveland head from austrailia probably in the 408CI or bigger range the manufacturer said 600hsp no problem, with a c4 trans. Cam size, stall conveter and other important decesions haven't been made. Right now I'm in the body process. The car is gutted a 351C block and c4 trans is in place, tubular automotive 1 7/8" headers will be here today. I'm now looking at the rear end. Springs need to be moved or gone so a mini tub can be done to the frame rail. I don't want the prostreet look maybe just the super stock look. As far as rear suspension I'm possibly going with Chris Alston adjustable street ladder bars, price isn't much more than caltracs and mono leaf and it seems to have more adjustablity. Tire size needs to be determined soon. I wan't traction and the right look. I don't want to large of a tire just what is needed. I see some cars with huge donuts in the rear and that doesn't excite me. After all this is done the car will be going on a rotisorie completely stripped to metal and start body work, I'm thinking Silver with dragstars and a 3" cowl hood. Thanks for all help Bryon
Bryon, with all you stated you will need the 28X15X10.5 with a good traction system. Not to many 351C fans left. greasemonkey, their are a lot of guys on here running the 10.5 without any problems. All I've ever done was to remove the top lip on the outside fender wells, and you can't even tell I did anything. Your rims must have some big offset, mine are 3.5 inches to the rear and I have 8.5 rims, no problems. When I run the 10.5 slick the outer edges (about 1/4 inch) of the tires doesn't quite make the contact that the rest of the tire does. I guess the 8.5 rim is a little narrow for the 10.5's. But I still get a better 60 with them then the 9 inch, but not by much. Terry
Back when I was racing my first Mav ( 1/4 mile ), I was running MT's 29.5 x 9 x 15 slicks. They fit nicely but I did have the fender lips rolled. I was running 5.14 gears though.
i am going to run M/T ET streets like don or BFG drag radials when i get the money for tires. i have BFG's on the back that will go on the front, and then i was thinking of keeping it consistant and get the BFG's for the back.. but i like what i see with don and how consistant he is with his M/T ET tires... why argue with proven results... he was the sportsman winner in arizona last year and is in 1st this year... who am i to argue with that?
