Did the installation of Comp Cams Stage 2 NSR cams for my Gen3/Cobra Jet engine a couple weeks ago and had the car tuned and dyno'd by Randy LaMance of Knox Performance Tuning at RM Motorwerks in Knoxville a few days ago. Car really woke up, and torque figures are really impressive. Their dyno is a Dyno Works 4 wheel drive eddy current which like a Mustang Dyno is a heartbreaker but the car still made impressive numbers on 93 pump gas. I have enclosed a comparison between the stock cams/CJ and the new Comp Cams/CJ combo. We also added the Comp Cams heavy duty primary and secondary timing chains as well as a new set of GT350 springs. Want to thank @2012-Boss for his expert help in the install work, makes it so much easier when 2 mechanics are checking and double checking things. One funny note, is the slicks were so cold we had to use the tire blankets to warm them up to stop the wheel spin on the rollers. First warm up pull filled the shop with tire smoke. LOL Screen shots are in standard correction, the chart and graph are the SAE5 numbers.CJ Manifold stock cams.jpgDyno Day 3.jpgDyno day.jpgDyno Day2.jpg

Stout numbers!! Was that with gen2 or gen3 heads? You picked a good day to go to the Dyno! Sure beats going on a hot day....

Well as many of you know I had a timing chain failure which was sad as the engine ran like a beast with the new cams. Going to a new longblock (again) but staying with factory cams. Just waiting on delivery today of the new GT500 oil pan and pump. Cammer engine will be repaired and put back in service later this season.

Happy to hear you’re making progress in getting back on track. It looks like you are getting proficient at swapping engines. I know who to call when mine needs to come out.
