What gear ratio are you running on your street strip car? What is the rest of your combo? What does it run?
Ran a 3.31 at the 2013 Nats pulled a best of 1.53 60ft and averaged a 1.56 all weekend 4000lbs 9.8 to 1 th400 100%stock suspension 325 50 15 DR's 3800 flash stall 9.5 Verter 115mph out the back 7.30's and 11.60's had some fuel psi issues so the second 660 suffered. Goes to show you dont "need" alot of gear to pull nice 60's if your on a nice track obviously
342's here. Ran 12.20 but my converter was slipping 1000 rpms thru the traps. Put in New JW 3000 stall and it's like a new car!!! I'll be hitting the track very soon. The weather is getting right where I want it lately. Hoping for 11.80-90
With a manual I found the 3.42's kept the rpm too low (4,800rpm through the trap at ~108mph), I bumped it up to 3.89's to put the rpm in the upper 5,000's. I'm running a TKO-600 with a .64 over drive so cruises around 2300rpm.
3.08 for me. Thinking of going to 3.55 when I make the posi upgrade, but truthfully with 14 inch wheels, the 3.08's are not bad. 3.55 would sure help my 60 foot times as I am sure the posi will as well, as I have to feather it out of the hole.
I am currently running 4.10s and thinking about going to a 3.55 or 3.73 Tire height is 28" The 4.10s keep me off the highway all together. What do you 3.55 guys say?
3.73's with a 28" tire will be 3.55 effective gear ratio. That is what I have. The Gear Vendors brings that down to 2.76 final drive. 2150 @ 60 MPH.
3.42. 26" tire, 464 turbo 400 10.71@ 126 mph. Convertible has 4.10, 462, SP400 13.90. Will go to 3.42 someday
Riv has the 3:42 but I dont race it (often) Regal has a 4:56 in a ford 9". on motor alone basicly stock 73 455 pulls Consistent 1.57 60" 4.80ish 330' and 7.50 -7.80 1/8 mile @ 89 MPH, depending on the air, on 29" MT Drags. those #'s get much better with a small shot of NOS
3.31 12 bolt behind a 550 hp motor in 4100# Convert - 11.93 was running a 3.08 (12.19 best) but changed gear for the 11 sec. timeslip .. also lost about 2 mpg doing 70 and above on extended highway trips
3.42 w/Eaton 30 splines and posi, 27" tall tire, Muncie 4 speed, 462 making 540hp/580tq, don't know cars weight. No ET's yet, hoping to dip in the high 11's but expecting low 12's.
JD Race supplied 8.5 10 bolt rearend 3.42 with Eaton truetrac posi unit. Currently running 275/40 R18 (26.6 high) handles great but terrible traction from a stop or slow roll on the street. Never raced at any tracks. Tony
