kn1ghtblade Posted March 30, 2007 Report Share Posted March 30, 2007 OK since no more 1/2 mile track... RIP : SAS (very very saddened) I need assistance with gearing for 2 different cars........... 1/4 Mile track gearing: 7.5 " chevy with T350 Tranny gear ratio??? 1/4 Mile track gearing: 8.5" chevy with Power Glide Tranny gear ratio??? 3/8 Mile Track Gearing 7.5" with the T350 Tranny???? 3/8 Mile Track Gearing 8.5" with Pwr Glide Tranny???? We are trying to figure out what we need now to run at the remaining tracks in the area and any help will be greatly appreciated.....

tps48 Posted March 30, 2007 Report Share Posted March 30, 2007 You better get busy or those tracks will be closed too....(for the winter!) LOL Link to comment Share on other sites More sharing options...
kn1ghtblade Posted March 30, 2007 Author Report Share Posted March 30, 2007 You better get busy or those tracks will be closed too....(for the winter!) LOL the one with power glide is basically ready to go, just need to know what gear to put in it... the 7.5 on the other hand is a different story... Still waiting on rules from THR before making a decission on makeing it a Street Stock for tri-city or a Hobby stock for THR.... Link to comment Share on other sites More sharing options...
Truck99 Posted March 31, 2007 Report Share Posted March 31, 2007 Not sure about tri-city, but for THR, I'd start with running your 350 transmission in 2nd (1.52) with a 4.10 rear gear for a 6.24 final. With the glide in 1st (1.76), you'd want around either a 3.42 or 3.73 in the rear end. The 3.42 would give you just a tad over 6.00 final whereas the 3.73 would give you 6.56. The 6.56 would require a pretty stout bottom end and a cam that favors top end. If you worry about spinning your motor too tight, stick with the 3.42 gears with the glide.

xcellracing Posted March 31, 2007 Report Share Posted March 31, 2007 what rpm are you trying to accomplish? Link to comment Share on other sites More sharing options...
kn1ghtblade Posted April 1, 2007 Author Report Share Posted April 1, 2007 For RPM I want to stay in the 6000 to 7000 range... Anything higher I am kinda leary of it..... Engine supposedly can handle 9-10 grand for stents but I am not sure the info is valid and we aint been able to get this on a track yet and do some testing since SAS closed... Right now I can tell you though the Glide is paired up with 8.5" rear with gears for SAS The T350 is going to go into my car with a 7.5" rear, which I have 273 and 342 gears for that rear end... The glide and 8.5 are in a car ready to go, but I can put my 7.5 rear in it quicker than changing the trannies out.... Link to comment Share on other sites More sharing options...
oldracer Posted April 1, 2007 Report Share Posted April 1, 2007 just bring them both to c.c.s. and check them out it all depends on how you drive Link to comment Share on other sites More sharing options...
HiTech Posted April 1, 2007 Report Share Posted April 1, 2007 just bring them both to c.c.s. and check them out it all depends on how you drive he has never raced before so .being a rookie .he probably wont turn it more than 5000 ..something aboult rookies and cc .the track is short tight walls tight turns ... and fast .so he will think he is going fast when he.s not ..so randy just bring it on down and race ...dont drive to fast and keep it out of the wall ..and you will have fun ..i garontie you wont hit 7000 .

kn1ghtblade Posted April 2, 2007 Author Report Share Posted April 2, 2007 hehehe Right now I am more worried about getting the p/s working again on that car... Manual steering on a tight track dont sound like too much fun... LoL LoL The gearing questions are more for future use, this comming weekend the plan all along was just to run it with the gears that are in it, then worry about changing them afterwards.... Right now I just need to get the seat time.... Link to comment Share on other sites More sharing options...
tps48 Posted April 3, 2007 Report Share Posted April 3, 2007 Old Timer, Youv'e never seen Knightblade drive, how do you know he wont hit that car? (#7000) I bet he hits something! Link to comment Share on other sites More sharing options...

kn1ghtblade Posted April 3, 2007 Author Report Share Posted April 3, 2007 I am just going by what we were told, I dont buy it though... I figure 7 would really be pushing it, although he did say he had it at 10grand going down front stretch at SAS in 1st gear all the way down the straight before he noticed and shifted gears.... Take it for what its worth its 2nd hand info even to us... LoL LoL We wont know anything for sure until we can get it on a track somewhere.... Right now we are only able to keep to the cosmetic repairs on it..... Link to comment Share on other sites More sharing options...

I'd offer to sell you a bridge in Arizona, but there really is one... Link to comment Share on other sites More sharing options...

Thanks Knightblade you kinda need to know wat gear is in the tranny the power glide could be a 174 or 182 ad it will make a big difference Link to comment Share on other sites More sharing options...
kn1ghtblade Posted April 5, 2007 Author Report Share Posted April 5, 2007 you kinda need to know wat gear is in the tranny the power glide could be a 174 or 182 ad it will make a big difference I wish we knew, but the previous owner I dont think knew either, we would have to trace the car back to the original owner/builder or to whoever originaly put the tranny in it... Or just pull it out and take it somewhere to get checked out... If we pull it out though we will just throw my T350 in it though since it matches up better with the rear end thats in the car, and the the PG matches up better with the other cars rear end..

xcellracing Posted April 6, 2007 Report Share Posted April 6, 2007 tO BE 100% sure as to the gear you need you should run the car over to your closest chassis dyno and find you tourque and hp curves and then gear it. If i were you i would run a 4.10 with your th350 and get around 6000 + rpm cuz i know for sure you are loosing power shortly after that amount of rpms.

Yea, we were thinking of actually switching the rear ends first, as soon as I get my 7.5 back together anyway... I have both 273 and 342 gears for it, to match it up whith the PG tranny, and plus switching rear ends is so so much easier and less time consuming then switching tranny's out...
