I've lost my mind.. or an MP90 on a 4.6L

Silver XJ,

I have read over your previous build, am I must congratulate you on your persistence in finding the root of your cam problem. Currently in my garage is a 200 TJ, 109,000 miles, and have installed a Avenger SC with Split Second to help with the fuel. (This is a 5 spd) Installed are the Ford 24 lb/hr injectors. For some reason I ended up slightly bending #3 intake valve. It threw a misfire code, and could hear a miss. Did compression check, and #3 is dead. Pulled head, and no marks on piston, and only way I knew it was bent was I removed it from head, and spun it in head.

So I have it apart, I have purchased new head, larger stainless valves, and the Mopar V8 springs installed. I want to install a cam, but am scared because of your experience, and do not know which will best enhance the SC.

What do you recommend? What do I need to insure my cam does not 'walk' or have issues you had? Any advice would be greatly appreciated.

Bump for updates. Did this get scrapped?

I’m thinking about doing this to my stroker and would love to use your CAD files as a base for design. It would save me a ton of time and money to not have to pay for an overpriced kit of mounting plates. I hope your project is running well. Merry Christmas. Thanks.
