So with a stock converter how radical of a cam have you seen people use ?

theman440 Wrote:Another cool thing about a reverse manual 727 is that there is no engine braking in first gear. I also dig how the engine revs up really high before the car moves when you have a high-stall convertorPlease explain . I dont know what you mean by engine braking in 1st gear . I understand 18 wheeler engine braking . Are you saying the trans ACTS like it has a stall converter ? Thanks . BooBoo

BooBooWhat it means is that when your in first gear and you let off the gas the engine free wheels (trans does not drag engine rpm down)

Oh , OK . What about when your sittin there ideling ? is the car trying to pull off or do you have to bring the RPM up like a stall converter ? If so about how much RPM is needed to get the car moving ? I,m just trying to figure out if I can use a radical cam with that set up .

let me clear up the engine braking in first gear. some have it and some dont. to get technical, it called "low band apply" here is what happens, say you are driving and want to slow down using the trans. you manually shift into 2nd gear, you slow down some, and then shift into first. without low band apply it will be like shifting into neutral, with low band apply, you will continue to slow down. without low band apply as you are coasting and the engine is ideling like you are in neutral, you hit the gas and the engine revs until it catches up to the speed of the car the the car takes off(this is bad for the trans.) as far as i know griner valve bodies have low band apply and cheeta does not.

Just wondering why you would not want to not a have low band apply?
Something to do with drag racing, keeping RPMs up on a burnout?
