Are the converters different for a V-8 verses the L6? I thought I read that somewhere.
From the factory there are different converters for 4 6, & 8 cylinders.
Remember the Chevy Vega?
Those had a factory 10" converter that probably stalled about 1800-2000 rpm,I put one behind my mild 250 6 cylinder,it stalled to 2600-2800,behind a mild V-8 3000 RPM easy.
Note: My th350 trans did not run hot with the Vega 10" converterIf you want some ummmf for the bottom end a stall about 1800 RPM should work pretty good.
With your cam choice & RPMs figured out I would say you should keep the RPMs around 2200-2300 for better mileage.
If you keep the RPMs too low,your mileage will drop.
If that converter stalls to 1800 rpm in a V-8 application I am pretty sure it will not stall that high for you,therefore not getting you enough stall as you would like for better take off.
I own a 1997 350 CI 1500 Silverado PU. the converter is horrible for takeing off fast, & I do mean horrible!
It brake stalls to 1200 RPM if I'm lucky,my 60 ft time is 2.4 -2.5seconds pathetic!
So basically what I am saying you would at least 1800 stall for you to be happy with the low end output of the engine.
Even with more stall, w/a lock-up converter you will get good mileage still when it is locked.
Two cents thrown :-)
