Mo power for my Mopar 340...

Skip the 1.6 rockers. There would be a gain, in most case's, but it's very little. If the engine was thought out with the lift in mind, that would be different.

T-Q's were stock. The general accepted ratings are 800 - 850 cfm.

Not knowing the cam specs makes any type of recomendation hard. But IF you want a new cam shaft, most of the power is in the duration of the cam and it's rate of lift. Quicker being better. Cams with that feature, a quick opening, ca be found in Comp Cams extreme hi-lift series, Lunati's Voo-doo grinds, Huges engines cams and specail order cams.

There a bit tuff on the valve springs, so it's your call on the installation of a cam like that. There isn't a streetabilty issue with them, FYI.

Just choose the duration that fits the RPM range of your driving and intended useage. Valve lift really should not exceed head flow abilty's.

The rest of the car specs should also be known. Car weight, converter stall, rear gearing. Etc.......

A 750 is fine if the car isn't to heavy or gearing to numerical low.
