As i have said many time don't be afraid to talk to the guys you will be racing against.They will probably not give you there secrets but they will get you close

[rockstar123]

Yeah that is good idea but can't talk to them over winter. Don't see them

what type car are you runnin for street stock? which tracks are you runnin?

[rockstar123]

running a car just got. it was run at redline lasr season by casey burch it has a 355ci engine with a turbo 350 tranny it has 323 gears in rear end thats all i got for you plan on running at skyline on saturdays, thunder mountain/afton on fridays and a couple sundays at weedsport

In my opinion, that gear /tranny combo will not work for Thunder/Skyline. A TH350 in first gear will give you a 8.13 final drive and in second gear you'll have a 4.90 final drive. First will be too much and second won't be enough. Redline is a lot smaller and has more bit than either of the tracks you plan on running. I believe most guys are running final drives in the  high 6's to low 7's.

If he runs 373's he should be ok,  3rd won't work on a 350 turbo. It will blow the pump out. We don't use 2nd in a powerglide so 2nd in a glide is 1.82 or 1.76 and a 350 turbo is 1.72.  So if he runs 3.73s it would be like running 3.42's w a glide. I'm using a 350 turbo, has 3.73's and turns 6000 rpms at a 3/8 mile.

I had 3.08 with my TH350 at Fivemile and ran in first ( Jerry witmarsh gearing from the 90's). Also heard of guys going 4.11 in second. i then Ran 3.42 with a powerglide and could not get out of the way. Change to 3.73 and finnaly felt fast. If you are new get gears and find your comb with your cam.

[dirtfan07]

I'm not going to argue but I know for a fact that a TH350 has a first gear ratio of 2.52 and second is 1.52. You can figure it out yourself, just multiply the tranny ratio by the gear ratio. Unfortunatly, the 3:23's you have seem to be in that area where no tranny will get you the final drive your looking for. I ran a TH350 in my Dog car and with tires that were 90" rollout with 3:08's in first gear, simular to what Zero said. 3:73's in second will only be 5.60 final (in second gear). If the tranny is good, change rear gears and give it a try. If your using a 7.5 rear, 3.08's are relatively easy to find. Check S-10's with 6 cylinders. Best to use 1st gear in a TH350, they "free-wheel" a little in second

1.82 and 1.76 are ratios for low gear in a glide, not 2nd, I think 2nd (or high) in a glide is 1 to 1

617 or 620!

With a turbo 350 in low gear 308 in the rear should be to much gear at any track. That's a 776 final gear. You should run a 273 in low gear. That will give you a 687 final gear or a 256 in rear and trans. in low will give you 645 final gear. Unless you can afford to blow your engine up. Good luck with what ever you decide.

If i remember correctly i turned about 5800 with the TH350 and 308's however the car was a comaro 3,600# car, back then I did not even get the engines balanced.

So u guys saying if I run 3.73s with the turbo 350 I would be ok?
