Short or long Glide?

[Blind Mule]

I am thinking about a shorty for my car I think with my peanut motor I won't have a wheelstand problem if so there is always wheeliebars   Who runs a short glide and what is the ratio?

I am gonna run the Phoenix 10x5.33 that is a big dang tire it is 12in. wide and has almost 104 rollout I like a tall narrow tire and not as much to drag around for my gutless wonder

Any idea on rear gear ratio just bracket car but want it to run good as possible?

I have about 4 convertor's but pretty sure I need the exact one for this car!

Anybody run a Paul's convertor he is from up North not sure what state?

I have customers with both short and long 'glides and they run varying low gear ratios. Same with final drive ratio--it all depends on tire size, converter, low gear ratio and where the motor makes power. We thought that we had it all figured out with Glenn Lever's car as he had dynoed the motor and knew how much power he had and what the torque curve was but the first time out the package worked well enough that he was bouncing off the limiter on the top end (Of course he runs a Pontiac and they don't rev that high--LOL)

ouch!  : )

It was an easy fix, bought some taller used tires and rims right there at the track. I have been running those ever since. The tires and rims that were on the dragster are now going on the gasser.

Blind Mule - for me, I just had our local speed shop build me a new shorty pg and ordered new convertor.  I put a jw ultrabell for Ford small pattern on it.  It has 1.76 1st.  Tires are 31 tall.  Untested yet, the mountain doesn't open till April.

Scotty Parks runs a shorty in his car, even with his motor waaaaay out there.  Done for weight savings and to free up space in the cockpit of the digger.

Randy As far as the converter goes you could send one out to a coverter guy and have it set up for your car . Those 10.5 tires might be too aggresive for your car but if you already have them why not try them.what we have found with my car is you need a little wheel speed or tire slip not a dead hook .Most of the newer FED's are being built with the motor a little further out . When Frank built my car in 2003 we put th motor out only 36 inches and it work's ok but it took a lot of effort to get things balanced out .You did not mention how much power your motor will make or how many rpm's it will turn but if you go on Mark William's web site they have an on line gear ratio calculator . This will  get you close .

My peanut might make 300  on a great day but later will step it up(I hope)

[denverflatheader]

Blind Mule - after looking at that mw calculator, are you any closer to deciding which rear gears are best?

[Tim G]

If you have a soft engine you're prolly gonna need a tall gear to get out the back door in the 1/4 without over reving it. Say a 56 or so.
I've got a left over 1:82 low ATI shorty kit for a glide you could get reasonable.
If you don't use a T-brake on 'em 1:82's live a long time.

[tylercrawford]

haven't made any passes but I have a shorty glide in mine.

1.76 1st, 3.50 gear, 30" racemasters.

Cam is supposed to make peak at 7200.

[Blind Mule]

I'm thinking 3.89 for mine cause later on I'm gonna step it up my motor now has a 3.25 stroke my 410 has a 4.0 stroke it should scratch off (I HOPE)
