Just wondering what your set up is and how it runs? Could you post a dyno sheet and/or time slip?

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.

I really wouldn't want my car finally comming alive by 4,500. On my smaller headed efi combo, I think the N-111 would come on sooner though. How much vacuum does your engine make?

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.
