Hello all
Confusing subject for me. Stall speed…lockup…10 or 12 inch, all are confusing to me.
Going with a carbureted SBC, 383 from Blueprint. Planning on a 700R4 transmission. Running the FFR IRS with, I believe, 355 gears.
Manual suggests 3200 - 3400 stall speed.
I’m not a drag racer. The occasional burnout is about all it will see. Decent amount of highway miles. Mostly to and from shows and Saturday night cruising.
Do I need one that high?
Do I need lockup?
Would a 2800 - 3000 be ok?
Any and all suggestions would be appreciated.
I’ve done some research on them through videos from Summit, but they just added to confusion. Cam numbers, exhaust numbers, rear gear combinations, all factor in (I assume)
Is there some sort of rule of thumb that would make the thought process simpler?

Thanks in advance folks!
Guy
