Sounds like you may have one of the earlier Keisler kits, you really need to remove some of the webbing on the transmission case that interferes with the floor crossmember, use a 4 spd hump, to get the transmission up into the tunnel to correct the driveline angle, and if you have a first generation shift tower, you need to upgrade to a 3rd gen tower for better shifting

I run a Keisler TKO 5spd .64 OD behind my 70 Charger 440 6 pack/450 HP, Dana 60 4:10, 27" tire, cam is a .470 with 1:6 rocker so in essence it's .520 lift and pulls fine in all gears, OD cruise RPM's are ideal for my set up, could be your cams duration that's killing your OD RPM's, one of the reasons I went with a smaller cam for shorter duration, but increased the lift with 1.6 ratio rockers


lift of the camshaft has nothing to do with lower rpm drivability, it is the duration & overlap that can make or break the cam choice with High gears & OD, my cam is a solid flat tappet 248 @ .050 in a 512 cid, it works great in my 68 Charger with 3.54 gear & .69 OD.
