According to the calculator about 5650 when I plug in the 1.45 trans gear @ 84 mph
I thought you did not want to go any higher than 5500
I don’t, but I plan to go to a 30 inch tire when these wear out so that will put me right there.
you guys didn't mention at 2.97's chrysler gear .
bob , what engine 383 400 like rpm on the high end , 413 440 better mid to top , well ? what cam too ?
Oh, 10-4 I did not know that.
What size is on there now? Can you take a measurement across the tire you have now? Sometime not immediately.
I counted the teeth when I put it in & came up with 3.08 but everyone says no 3.08 came in the 8 3/4. Im going to pull it ASAP & count again.
Have no idea what cam. She’s lumpy
i think 4.10's would work out well , 3.91 are okay , that short stroke 400 and big bore piston like rpm . don't need much head to get it to breath . i would think its some were in the 5500 range for its peek with stock heads , if it was high c/r then 6500 . better heads and then 7500 plus . my 63 fury ran a 383 with giant c/r n heads with a single 850 on it to 8000 rpm , stock rods n crank just polished to mirror finish everywhere , and a giant cam , solid tappet type , 4.89's 30'' slicks 2'' primaries 3 1/2 collectors 12'' long open headers . ran 10.73 in ihra , all metal car , alum inner fenders wells , replaced the steel ones . this 440 +.06 maxwedge street package , pump gas c/r was running 11.82 flat at 6200 through the traps . just like i drove it , same rubber on the rears n 2 1/2'' through the muffers . here is a shot of the last timed at the track , that was before the fresh air version of air cleaners , as you can see they got pushed up into the air which was an issue if i wanted to run the scoop .
we need to get you gear'd up , lol .
The ratio will be stamped into the crown wheel.
Yes it’s on all my non Sure Grip pigs but didn’t see it on this one.
That's strange since the crown wheel unbolts and is interchangeable between sure grips and non sure grips.
