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.
Agreed, well aware of that, I mentioned the "lift" of cam that I chose as being the determing factor of the duration I desired, I achieved the lift value I wanted by going with 1:6 rockers, this was to avoid having a cam made to spec...I mentioned above several causes for the poster to help determine his ills with his TKO set up...duration was one of them, as the poster released no information to help in that aspect
Thank You
