You can have some chop even with only 220* and some negative overlap. My 224 cam checked in with -4 but all you have to do is pull the timing at idle and she will chop.
So Martin's cam would be a good choice for me? Would it work ok with stock heads? Upgrade the springs and rods is obvious, or will I need new heads?

I had a whim that you were in a round about way saying the same thing I was. You got all the tuning knowledge though on these set-ups, I'm just an ant to a giant in that regard!

It seemed to work well!

If I had my choice to choose a cam for your engine it would be one of my positive displacement cams, but that said since you asked about the two cams you brought up, I still think the Stage One would work just fine. It would give you a little more burble/lope at idle also.

I have a 222/240 118+4 and a 230/248 119+5 for positive displacement cams.

not trying to hijack the thread but it's a little off track. With a small positive displacement blower like the mp112 do you want your gearing to be on the taller side to take advantage of the low rpm torque?

I think that's the general idea, I was planning on staying with my factory gear or maybe a 372 at most. I have a M6.

So will the stage one help me better to reach my 500hp goal, or should I go with a positive displacement cam. I do love the sound of a cam, but if a little chop/blurp is going to ruin my power goal I can let it go. All you guy's at Tick have not let me down, so I trust what you suggest!

I would like to see what the smaller of the two does with the 112, I think it would make some good power.

I could possibly work up a custom grind for you that still kept the overlap in check, but gave you that little bit of lope that you would like.

Well, I guess that settles it. I will go with the stage one. What heads would you recamend for this settup? Or will my factory heads be able to handle my needs?

Thanks

I think a set of ported heads or aftermarket heads would be better than factory, but that said you can get make pretty good power without them.

Looks right on the money, Patrick is very well versed in any set-up.

If I could guess which this is a guess since I haven't seen either of those cams on our dyno, I'd say 10-15rwhp MAX.

Default Mp112 rotor knock or slap with a cam

I know this is an old thread, but did you ever do the cam swap? Did you experience rotor knock or slap at idle with the MP112?
