Th350 and RPM's
Th350 and RPM's Ok not complaining but just wondering on something here. I have '95 Formula, LT1, LT's, LTCC, TH350 w/Yank 3600. I just recently did the TH350 install, about 400mi into it, and I have a question about the RPM's it turning. I used the F-Body chart for ratios of the th350, tire size, gears, rpm ect to get an idea of what RPM's it would be turning and I am WAY off from the chart. I have confirmed that I have 2:73 (terrible yes) in the rear. I counted teeth myself. But I am turning 3000rpm at 65-68mph. According to the chart I should be doing that at closer to 2300-2400 rpm. So is somethings crazy in my tranny? I did not think the ratios in the th350 could be changed but I'm not sure what gives? My only other thinking was it didnt really have 2:73. But I am now positive it does. So is the stall causing this? I'm lost. Like I said, not that I'm one complaining on gas milage. I would not trade my two V8's for anything!!!
I have 323's and at 3k in high gear Im at 65. I don't do the mathematical formula stuff, bc to me it don't matter. I hate turning my car high rpm's so when I take my car out, I cruise it. try not to take it over 27-2800, just let em come around me.
that's not bad at all, my stock converter and a 27" tire with 3.23's is turning about 2700 at 65ish(speedo doesn't work well).
I figured it was probably converter slip. I dont take it over the 2700-3000 mark when I am just cruising it. I figured much over 3000 wouldnt be to healthy in the long run. I am using a GPS speedo right now off of my phone, I have been to lazy and cheap to finish that part of the project. Been hard enough to keep my foot out of it for the break in on the converter!
But now thats in I will say the Yank converter was well worth the $

do you have a short tire, and is the speedometer correct
loose converters and tall gears dont mix great, was the converter custom built for the cam, rear, and tire size-anyone of those changes will change stall also
lol, funny, with older cars, we are installing OD's, with newer cars guys are rem OD's-of course, a non OD is def a cheaper choice

Yeah it was custom built to the car. Using a GPS speedo so I know that's correct. Running stock tire size and that was also some info figured in for the converter.
Haha yeah I had one toasted 4L60 and my second one was acting up big time. I had this th350 here already so I figured why not!
