Stall and Shift RPM Question.

I agree with Johnnymac on that. 3000 RPM is for a HUGE cam and very high performance engine. I have pretty aggressive engine a "non mild" cam, and I have a 2500RPM stall converter in a brand new 727 I got from Summit Racing (via Performance Automatic). A 2500 RPM stall is all I need, and a 1900-2000 will work great for you. What that means is that when you are sitting with your foot on the brake in drive at a stop light, as you engage the throttle your vehicle will start to acclerate (as if you had just started to slip your clutch if it were a manual trans) as you hit 2000RPM and say about 20mph) you are now "locked up" and your shift point has nothing to do with your stall converter, your "throttle kickdown cable" on your trans has a lot to do with your shift point...if you keep your foot to the floor that tells your trans that you are not ready to shift yet eventually it will probably shift about 4500-5000RPM on it's own (even if your foot is still on the floor) depending on what shift kit is in your trans. Same principle applies if you are cruising at 55mph in 3rd gear doing 2400 rpm (you are locked up in 3rd gear). IF you smash the gas pedal, your throttle kickdown cable on your carburetor (goes from carb down to your trans) should tell your trans you want to drop into second (and at that speed it is probably about 3500-4000 RPM) It will stay in second until you either lift your foot off the pedal, or until you hit about 5000 RPM and then it will go back to 3rd.

I am NOT a trans expert. I do not rebuild them or work on them. Just going off what I know from my car (I had the 904 and now the 727). If all this stall converter stuff feels over your heard (I have my limit and when I cross it I ask for advice from a mechanic) find a guy that works on transmissions (not your average transmission shop). Also I would highly recommend you call Performance Automatic and ask to speak to one of their techs. They can help you and you can eventually buy any parts you need from either them directly or Summit Racing for a cheaper price (they sell to summit) http://www.performanceautomatic.com/

Good luck!
