The lifters are definitely good for 7000+ RPM. Had them run in a 331 stroker and they are hard to beat.
Your problem, I feel, it with your distributor. At around 6000 RPM you are pushing a lot of air into that chamber, very rapidly. Your distributor will DEFINITELY have a problem if it is the stock piece. Alot of air and fuel is nice but if you can't burn it, it is of no use. It won't be able to accurately advance the timing so aggressively, seeing as the original 85 mustang topped out revs at 5500 rpm.
Another reason why you might not have experienced this problem with the higher compression ratio, is that the higher compression ratio would have helped out igniting the mixture by just compressing the mixture itself.(similar to how a diesel works)
I would consider getting a better distributor, thicker wires, a good cap and rotor, and some top notch plugs that are properly gapped.
Best of luck!
i know a guy who was running 8.90's in the 1/4 with a 347 and a stock 302 distibutor. he advised me never to waste my money on an expensive distro...I can't believe your running in the 11's and you are still using stock ignition pieces.

I mean his car was fast but dont you think it would be quicker if he invested the$200-$300 on a better unit? all i know is he was fast with the stock one, thats for sure.

Ok so he has a stock unit. How much money has he spent upgrading the stock unit? He must have done some work to it. 200-300 bucks on a car that runs in the 8's is not much money.
Modular what ignition system are you running? All stock?
Another question is how did you set up your cam? straight up or 4 degrees advanced or 4 degrees retarded?
Ok 4 degrees advance on the cam would give you more top end. Thaty would be good if you plan on pulling it closer to the 7000 rpm range.
Another thing to consider is you installed a vic jr intake right? By doing so you lost a lot of low end torque. I have talk to other people who were not happy with there cars performance after that mod. Personally i still want to try it on my car. I think the nitrous will like that intake more then my wiend stealth.
i have heard the same thing.....i think the motors need to be spun higher. Ill get back on later, i have a date with the dentist
nasty. I'm glad i was just going to the chiropractor.
Yes get here spinning higher. It's such a hard mental block to get by to take a car over 6500 rpm in my opinion.
