The car only stalling to 17-1800 sounds like it’s got a stock converter . This thing needs to stall like 2800-3000 ish given it has a decent cam and it’s short in power .My bad, Im new here, didnt say the other posted haha.
They told me 10.5:1 compression
Cam: Elgin E1836P
Intake Valve Lift: .542"

Advertised Intake Duration: 286
Advertised Exhaust Duration: 289
Intake Duration @ .050": 224

I'm not sure on timing as I had someone time it, he just told me to put it at 10 when I brought it and he added timing through the tune
So, the converter is supposed to be a 2500 stall but the car only stalls at 1700-1800, second time this has happened with a converter for me
Stalling 17-1800 means it’s way to tight . I have a built FB aod in my own car with a custom PTc . Our combos are much different though.
Either way I think your lack of power is in your converter . The 5 mm in throttle body is not going to help .
Sure porting the heads will always help , correct springs are key .
But the converter flashing at 17-1800 it may as well be stock.
