MY dyno and ET slip, What do they tell you?

shhhhh... don't let the secret out! LOL

Guys will spend thousands on making more HP and cripple it with a cheap converter. Ask them to spend a couple of bucks, 500-1000 on a quality converter and you'd think you shot their dog...

Not a fan of that particular brand, but, if it works for you, great. If it was 3600 behind a 440 it might be in the 4K range behind your stroker.

Hope it runs like you hope.
