74, What is the rest of your combo like? carb, ignition, headers, intake, etc... The more specific you are the better.
Dude, I have no clue why Edelbrock says use a button. I didnt think I read that but I have to confess I don't shop that manufacturer for cams. You dont need a button on a small block mopar as the cam is pulled into the block as the engine rotates because of the cut on the cam's oil pump drive gear. The RPM cams are a type of cam I dont like. They are technology from the 80s and they are not very fast rate, nor very high lifts in respect to the intended power curve. I know there are much more street friendly cams out there.. Plus I'm no fan of the lifter Edelbrock uses. The plunger retaining clips always seem to want to pop out of them. As far as stall speeds, there are asmany opinions on this as drivers. As for what I would want, I want something with no more flash stall than you 55mph engine rpm. With 3.55s, a stock type 26"tire that's around 2600-2800 depending. So I'd be looking at a convertor with an advertised stall around 2400 tops. This is a street car setup. A racing setup would be higher, but truthfully a race setup wouldnt be running 3.55s and stock tires either...lol.
