For anyone reading, I'm going to make sure I have timing dialed in as well, per twisted6 recommendation. Maybe try an aftermarket ignition module as well. I have 36 total advance, which the engine seems to like. Though I do think it's coming in a little late, probably full advance at 3000 rpm, so it may like it to come in closer to 2500 rpm. Played around with different spring kits in the past and can't ever seem to get timing to come in early enough without it being too early or getting way too much at higher RPM. I'll have to keep playing around and find the balance.
Will post with any updates if I find some more speed.
Might not be that something major was wrong as I was thinking, maybe it's some small things stacking up, fuel being a little off as mentioned above, timing not quite perfect.
Anyone else with a similar engine setup let me know how yours runs or what kind of times it does (1/8, 1/4, 0-60, dyno graphs etc). I don't have any good comparisons, so maybe it's performing better than I think. I don't have official drag times or dyno numbers. Not really a race build, just a fun street engine for a truck. But still want to make sure I'm getting what I can of it after putting in all the work on this build!
