I don't have the 6 speed but I have the Tremec TKO 5 speed. It is a easy fit and gives you a 3.25 first gear and .68 overdrive. I have 4.11 gears at first and 60 mph was 2200 and 70 was 2500 . I then switched back to 3.08 because of traction problems in the first 3 gears and now turn 1600 at 60 , 1900 at 70. It goes up 300 rpm for every 10 miles per hour.SwaveDave said:Im very interested in this trans. If you have it, how do u like it ? What is your rpm in 6th travelling at 70 mph ? DId it increase your gas mileage on long trips ? Pros and cons ?
Would you consider your car "streetable" or "cruiseable"? If so have you done any traveling in it and what kind of mileage (gas) did you get?I installed the richmond 6 speed last year got a great deal.For the most part the transmissions is great except 6th gear cant handle road racing conditions I broke 6th gear and up graded to the .80 gear from the .76 gear Not a big rpm change but it is a little noisy because of the straight cut gears IMO the .76 gear would be fine as long as you dont try pushing 130 plus road racing Talked to couple other open roadracers running the same transmissions and had same problem Otherwise great transmission would recommend to anyone Also alot of gear ratios to chose from and real easy to work on Converted from auto and this is the best thing I have do to the car
Could you tell me about your car and about this 1.5 mile event?My car is very streetable and cruises the interstate great The mileage I'm not sure don't keep track and I have a very hard time just cruising in 6th gear and just got the right size carb for it and now it snows so won't get it out except to tear down to up grade so things hope I was of some help Like I said it was the best thing Ihave done to my car and I have modified just about everything to go faster and ride better Should make 2010 Sandhills Open Road Challenge for the mile and half mile shootout First time I believe 150mph all Iwill be alowed Three other guys I have met run the Richmond 6 ROD and have no complaints except 6th gear at 150 plus breaking Well hope I have been some help
I have a 79 also. With one of my older 383 ci solid roller motors I was able to go 165 mph in a 0ne mile event.Richmond 6 ROD 3.55 gears(changing to 3.08) Hooker headers and side pipes Areo 15x10 front and 15x12 rear Nitto 275/50R15 front &325/50R15
