I have a 309 first gear in my 4.10 geared Roadrunner with a 28 inch tire. (275/60R15) and let me just say it's too much gear. It's a quick shift. Use 355 gears or a tall tire. This is with a 450 hp 440.
I have 4.10s but also have 30" tires so it will help. I like the slr for the street/na even if it is a bit much for the nitrous, the car is going to be a compromise.
Understand and have had allot of legnthy discussions with some smart guys and that's the plan with the clutch tamer. The guys that are going fast with manuals and drag radials are using adjustable clutches. I don't know if you are familiar with the et street radial R but they are a different animal. They are a radial type construction but use nylon plies and are very light/pliable compared to traditional drag radials. It's the first radial that mt advertises as actually having some success with manual trans cars. Up until now I always ran auto cars and man drag radials are so nice compared to slicks for the type of street strip I do.
I currently have a cast iron overdrive in the car that I was planning on hitting the track with but I had some issues with it and decided to hit the easy button and throw in the std. a833 with the low first. After I get the car dialed in I am going to swap the overdrive back in and really see how much difference in et there is.
They were a factory trans made from 74-75 for the 318 I believe and they have a 3.09,1.92,1.40,1.00 ratio. I had two and I put the first one in my 71 340 duster with 28" tires and a 3.23. gear, made for a really nice street car.
I believe it's early A body stuff, like 63 to 66 both slant 6 and 273. 309 first, regular 2nd unlike an OD.
Everyone told me that as well but it ran fine. A stroker will barely notice it.
You are right, its hard to shift when there is such a big drop, heavy flywheel/pressure plate but Yr helped me work through that with slick shifting the trans. It's still very streetable when you leave the synchros in and just grind every other tooth off them as well.
I think I've done it all three ways with my Duster. When I was drag racing on a regular basis I used full slicks and 4-in skinnies in the front. But unfortunately that was before I had any experience with the clutch tamer.. I never use the slicks on the street I always had a separate set of rims and tires was just street tires.. those were absolutely no fun on the street as it was like being on an ice skating ring... Especially with the 410 gears.. when I switch to 355 and a friendlier cam it was much better on the street but the drag radios made it the most enjoyable... I went with the nitto 555 they were at least $100 I want to say each cheaper and the jury was completely split on which one was better than the Mickey Thompsons...
That is the plan my man!, and I will be easy on the nitrous until I can build my R block. The plan is to use it progressively and run it out the back door. A guy I know won the class this year, it was pretty cool and well deserved.
This is where the clutch tamer becomes a bit of a game changer...
