I cant really adjust the timing with a light, because the balancer seems to be spun and when you put a light on it, it says its at 50 degrees advanced. which obviously is wrong, because it wouldn't run, the timing seems to be adjusted well, I'm probably right around 30-35 degrees advanced if I had to guess. my local engine builder whom built a 327 with me fine tuned it by ear, by adjusting the timing manually, and he's been working with GM small blocks and BBC's for years.
and the rear end gears are the stock 3.08's but with a BBC and a TH400 that's best compared to any taller and the lowest would be 3.42's
I guess i could have the springs and weights adjusted, it would be nice to delay the shift a bit more, the truck would seriously get up and go if it did.
And i realize i need a stall, but wouldn't that only help on takeoff only? the truck spins enough when you touch the gas while taking off haha. And if i did a 2500 RPM stall i wouldn't really notice it while driving as it's probably in that RPM range at cruising speeds around 50-55MPH correct? I believe a TH400 has a 2000 RPM stall convertor stock as well.
and I'm pretty sure shifting a TH400 manually isn't a good idea, since they're vacuum operated when you shift you'd have to let off from WOT? they're not like power glides. i don't want to hurt the trans either
