Yes it seemed low to me but I had to consider these things , I've never been on this Dyno before (it is a Dynojet) as this is my first Chevy and I switched tuners to someone the LS community around me recommended , also I never got any base numbers (which I really regret now) so I don't know where I started and if the Dyno does read low I might have picked up close to what I should have but I'll never know now . And yes I stated in my above post it's a stock throttle body and intake , and I really wouldn't call them ported , what was done was the casting flaws were removed and smoothed out and a little material was taken out of the front side of the throttle body and polished (none was talked out behind the TB blade on the intake side) I would say it might free up 5-7hp at most . Also my heads still had some of the factory CNC grooves in the intake ports , looks like most of the porting was done on the exhaust side , I don't port heads for a living but I've seen enough to know that there is a lot left to be done if I chose to , he calls it a high velocity street port , dont know what that means exactly

Sorry, I missed that. With as much camshaft as you got there, I just assumed you went with an aftermarket intake. There is an easy 25hp to be had with a ported Fast, and possibly more with a ported MSD. That would put power about where I was thinking it should be. With 232/0.050 intake duration, and that much lift, AND the bump in SCR, you should be ~575. The larger TB, in my experience, isn't worth the money. Hardly noticeable gains or improvements - and I also do my own tuning, so it's not like I'm talking out my ***. The intake port does not require much work at all.....The exh side does.
