RPM H/C numbers...
Just got my car back from RPM in De after their AI/B3 combo. Couldn't be happier with the numbers for a stock intake/tb. Haven't had a chance to drive the car yet, just on and off the trailer, and into the garage, but I was expecting to have to work the clutch much more with such a large cam, but not at all, same as stock. I'm sure it has some big cam tendencies while driving, but I'll have to wait for this damn NE rain to stop to take it out.
Props to the guys at RPM! Communication was great, they were quick to answer my questions and concerns. Great shop, that produces some badass results!!

Before numbers
What if any mods did you have before going into shop.

Nice gains. My car was there in late May/early June for heads & tune only. Those guys were a joy to work with and very happy with the work they did.

What rear tires? It looks like they stopped the dyno runs at about 6500 RPM. Very nice gains over stock.

Every time I start looking at some more exotic/custom h/c setups, I keep returning to the RPM B3/AI package. Just too easy to make a plug and play 620+ whp with it.

A buddy with a Mamo MSD/NW102 with the RPM AI Heads/B3 cam made 607 SAE at a shop in GA. He is now Hi-Ram though, I would of loved to lined up with him on his old setup (still take him on with his new setup as well).

Haha, I will try! The Mantic Twin goes in next weekend and then 500 mile break in, then Hi-Ram hunting. I am not too worried about them though, top end they will pull away. I really just want to run an RPM B3/AI/Mamo combo to see how it all stacks up.
PRC 285's milled .030
Tick 24x/26x cam
Ported MSD/NW102/Halltech 108 w/Vette Air Scoop
ARH 2" with 3' catless X-pipe
ATI 10% UD
FIC 850cc Injectors
MGW Flat Stick
Mantic Twin going in next weekend
Dyno on old setup was 572 SAE (Vararam CAI/no ATI 10% UD/no NW102/more conservative tune).
Hoping to see 600+ SAE on the same dyno after the clutch is done.
The dyno is a measuring tool, I am sure I could make more maybe if I went to a different dyno.

Ben, that car of yours has came a long way since purchase. Moreover you have wrenched on it yourself. I don't possess those talents. Therefore, you should be even more proud of your build. Kudos friend...

Just drove a 150 miles to a weekend work thing. Wow, can't believe how close to stock this thing drives!! Take offs require a slight more clutch work, but apart from that, damn near stock. I don't use 6th gear on the interstate bc exhaust drone is so bad, but I set cruise at 70 in 6th, 1500 rpms, and it was fine. Some slight bucking in 6th at 1800 rpms, but nothing drastic.
beyond impressed with the drivability and power!!
