Not sure what mine runs or Dyno's yet, My 30# and tune go in today, I do not have a MSD or AS&M 58mm TB though....I am going to the track tomorow, so I will see what it does in the hell heat. As far a drivability, I drive mine every day. It not great on gas around town, but still good on the highway.

Do an 847 search you'll find a ton of info, I recommend a custom grind, I ran the 847 w/1.7rrs and all the boltons, stock cubes for a year or so & dynoed 373 & ran 12.6 1/4 ET. Badass cam, still recommend a custom grind though.

damn Ellis, that's awesome you got almost a full second better than me with the 847, maybe it was the driver 
The new setup is gonna put it down hard, the new chassis/suspension is going to hook it up good I believe

Yea it ran pretty well for a 350
just was not as consistant as I wanted. By summer it had slowed down to 12.20s.It's not offten we get Texas Weather here...and when we do you better hope the track is open
We just had that cam in a 396 and it made 437RWHP for a loss of 11hp over the cutom cam we were using. With the 238/245 cam the car made 448hp/453tq at the rear through an Auto and 12 bolt. Next we are going to have Bret cut a cam for it and try again.
BTW we played with it on the dyno with the 847 and managed to pick up over 30 RWTQ with just a little timing and fuel
This is the second Shop car. 396 C.I. ,LE AFR 210s ,Hooker LTs ,SSEFI proto Intake , and a Stock opti sytem
Good luck!
OH yeah one last thing! Last time we were at the track with this car it was yanking the wheels with 17 inch ET Street Drag Radials and a STOCK TQ arm

Yup we already have the other cam back in and we are going to have Bret design a pretty nasty HR for it. Jim wants 475 Rear wheel or more out of it
