Yeah, I run the N-111. Never ran the 91. Last time at the track I had the 60's down to a 1.508 with my new coil over rear suspension (best previous was a 1.576) but the car wouldn't MPH. Best MPH was 121 which is about 3 MPH off what it was running. It was fluttering up high in the rpm range. Found bad valve springs. Just swapped out and also found a rocker coming apart. All fixed and ready to go now and got a different spring rate for my rear coil overs. Hoping for a new best on the 15th. I really want to go at least 10.60s on ET Streets with this combo before moving on to bigger, higher revving things.

I have a 331with Flat top pistons, AFM N-91, Vic Jr heads, Vic Jr intake, 1 inch spacer, 750 HP carb. Still have bbk 1 5/8 shorties, 2.5 inch hedman H-pipe, Flowmaster 2 chamber 2.5 inch catback. Stock t-5 (not for long), centerforce D/F clutch. Dont have any numbers for ya...sorry, But I fired her up last night...sounds really pissed...need to tune and adjust the rockers, a few little things here and there then I will get you some track times. The above combo that goes 10's has me excited! I also plan on running a 250 horse ZEX perimiter plate system...Hoping for 10.50's...all this in a 1994 Mustang with tubular k member, and a arms, coilovers and meats and skinnies.

I think you'll be happy with it when you get it tuned in. The 91 has a little less duration than the 111 but it's still really a stout cam for a hydro roller. You're definately going to have the ponies to munch that stock T-5.

The 111 is 248/258 @.050 110 lsa. .576 lift with a 1.6 rocker. Both are definately not supercharger cams.

Not sure, the best thing to do would be to call or email them and they'll discuss your combo and make a recommendation.
I have EMW150's graph on my computer, he sent it to me a while ago 
Eric, hows that n-111 drive on the street? How much vacuum does it make?
You know me Rick, always doing a little research to explore future possibilities.
aleborjas, the afm b451 is a cam for higher rpm supercharged 331/347's.

I have a dyno sheet from a guy on corral with a victor jr headed 331 with an N91 cam, a TFS R manifold, 90mm tb. I'm not sure what exhaust, either 1 5/8 or 1 3/4" longtubes. Here is the graph. Your exhaust is gonna hurt you.

OK, I remember emailing you that now a while back. As far as driveablility you have to run a steep gear with it. I run 4:56s and it works great. It drives surprisingly well but doesn't really come alive till about 4500. Not much vacuum though. I do run power brakes on mine and somehow it manages to have enough for decent stopping without a separate canister.

Like Grn92lx said, the exhaust is going to hurt you a little. A good 13/4" header with a true 3" collector and 3" pipes would really help you. Still though carbureted I think you'll be right around 400 RWHP peaking at about 6800.

Thats what I thought...Right around 6800 was gonna be the shift point...possibly higher. I know the exhaust is what is hurting me...but its just so damn easy to pull the motor without longtubes...although...I have a tubular k member now...Possible new exhaust in the future...maybe If I can find some good used stuff...I dunno, We will see. Thanks for both of your guys' help...I appreciate it!

I know, I cuss my longtubes everytime with the Lakewood bell. Good luck with it and let us know how it does for you.

It isn't as bad as you probably think. It still has decent power down low. I don't have to downshift for hills or anything. I can't remember ever checking the vacuum on it.
