Factory High Stall Converters
Here is a 5.2M factory power curve;
Notice the beer-keg torque curve; you won't get that shape with any other factory SBM. But that's not the point. Look at the power down in the range of 1800 to 2800.
At 1800, it looks to be about 90hp,
by 2400, the power is up to say 130hp,
and by 2800 it looks like 155hp
That is all made by the odd-looking torque curve, but the story is similar for a none beer-keg engine;
namely; How much power do you need at take-off? On a streeter the question changes to, "how far do you wanna smoke your tires"?
I'll take the 2800 if you don't mind, and if it spins too much.......that's what a tunable Air-Valve Secondary carb is for....... right? lol.
Take a survey among streeters ask; is it better to have a lil too much power on take off, or a lil not enough..... lol.
That's why I have a clutch, and a 750 DP carb ......... dial-a smoke.
