MS4 Cam Only, before I sheared a rocker bolt**
It made about 391 peak hp and I think 380 peak torque.
Mods
MS4 on 111LSA
PRC plat double springs
7.425 PRs
Mac mid headers
Off road y
Borla CB un corked
MTI Lid
LS6 intake
stock pulleys
home ported TB
stock rockers/heads
12 bolt w/ 3.42s
Tuned by Pat G
This was on a Mustang Dyno, they were a little disappointed with the numbers.
Either way, ill get a graph up tomorrow when I get to scan my graph results and here are some videos before she blew.One un-tuned and one tuned.

at least one rocker bolt broker and the rocker came loose on top of the head, sounds real bad, I am tearing apart tonight to diagnose. Next plan, in a week or so, is to have 799 heads so I will hope for 420-430 on the same dyno with the only difference is a correctly assembled and functioning engine as well as the 799 heads

It was nice meeting you Brian. I'm sorry you had mechanical issues, but I look forward to seeing your new setup. Just remember to select heads that don't make P to V clearance worse. That MS4 cam is already tight as it is.

I will be driving back to you in a few weeks, whenever you schedule is free, I hope to have everything buttoned back up by the beginning of next week. So maybe not this weekend but the next I can come down there for a re-tune

yes sir, plan to do 4.10s and possible swap for lower OD gears to obtain stock hwy mileage. After the heads are on, I know the clutch is going to begging for a swap as well as all the hydraulics, so the rear end gets put on hold.

With Stock 243s I thought it was about right, Im looking to get them ported or buy a set of patriot heads..but Iv got a question, my clutch started sliping BAD the day after I got it dynoed on the dyno jet thats the one in the vid. and my hp and tq.. tq mainly have a dip in it from 3600-5000..could this be clutch slipping? It would still peak the same hp right? The guy that did the cam/tuning said a set of heads and a fast 92 would greatly help me..
