New cam for my 408.

Well I got all my parts in and was able to get the cam swapped and new lifters in yesterday. Thanks for all the input fellas. I did end up going with a custom grind from comp. very similar to what I posted in my first post. With just a small change in duration. I put in a set of morel hydraulic lifters. I'm hoping to get time Sunday to drop the motor back in. If my sons go kart race gets cancelled because of rain I will get the motor back in. I will let you guys know how it behaves.

The motor is in and seems to be running well. Only got to drive it a few miles last night after I got the motor in. It's very snappy and has a ton of power. The motor is a lot quieter with new cam and smoother. Still have some tuning to do. Need to drop in some smaller jets and adjust timing a touch. I will let my engine builder take care of that. Here's a pic and video of first fire up. Has slight hesitation in video but it seemed to go away after it ran for a few more minutes and I got fresh gas in it. The gas was OLD from October last year. Put some fresh 93 in it and ran great.
