230+ duration cam cars.. how useable is 6th gear? I'm trying to decide on the rear gearing for my setup, and will be going with at least a g5x2 cam. What is the lowest rpm that the car likes to see in 5th and 6th gear? I'm looking at 4.10's and with my 285/30/18 tires that would put me at 1500rpm's for 55mph, and 2000 at 70. Seems like the big cams wouldn't want to pull that without protest.
Thanks
Thanks

Re: 230+ duration cam cars.. how useable is 6th gear? I have the G5X2 and 3.42s. I can cruise in 5th or 6th down to ~1200 rpms before I get any hassle. It does start to buck some in the lower gears though.

Re: 230+ duration cam cars.. how useable is 6th gear? Thanks guys.. Brains, I'm going with a cam just a few degrees give or take what you have, so that's some good info. Thanks again,

Re: 230+ duration cam cars.. how useable is 6th gear? My 230/224 only misbehaves at under 1200rpms in 1st gear. Every other gear is fine. My aluminum flywheel exaggerates the problem too.

Re: 230+ duration cam cars.. how useable is 6th gear? my F1 cam will do pretty much anything the stock cam did after a great tune. It will pull fine from 1000 RPM in any gear

Re: 230+ duration cam cars.. how useable is 6th gear? 6th gear is just fine to use anywhere i would use the stock gear. the real problem is cruising real slow in 1st or 2nd. while it's not that bad, it will buck if left in gear and just a small amount of throttle is applied. like while driving in a parking lot. you just end up letting the clutch out to go, and then pushing it in as soon as you're done on the gas.

Re: 230+ duration cam cars.. how useable is 6th gear? My 231/237 does just fine in 6th with 3.42 gears. I cruise along around 1,400 to 1,600rpms without a problem.

Re: 230+ duration cam cars.. how useable is 6th gear? I see some slight bucking while driving through school speed zones (15mph). But it's very manageable. Elsewhere, no probs.
