This.
I could go with a higher stall, but then it wouldn't be as drivable on the street when I do drive it more in winter, and when I need to tow a buddy's broken car home or haul firewood/mulch I'd have to worry about trans temps... I built this thing to be quick, while still towing better than a stock truck. It's not a race car, it's a pickup.
And if I went with a higher stall, then it'd be "why not go with a bigger cam?", and then "Why not do heads?". I like my simple setup.
As the truck sat, there were two weak spots: the wheel/tire combo, and the fact that I'm still only tuned for 87 octane.
My original goal with this thing was high 13s on a good day, and I've FAR exceeded that.
My new goal is high 12s on street tires, and regular fuel. When's the last time you saw ANYTHING make a 12 second pass on 87 octane, let alone on street tires, and weighing 5000 pounds? If I can't get 12s this fall I'll get a second PCM tuned for 93, but I like being able to buy the cheapest gas I can find, and not worry about it. The truck doesn't get driven often, but when I drive it it's usually on a long trip.
