Re: Trying to figure out a direction to go with cams.

Yeah I think it was packed fairly safe. Triple boxed and no movement.

Re: Trying to figure out a direction to go with cams.

This is from jones, I would like to believe that the cam itself is most likely in the box in one of those hard pack plastic containers. Have about 6 hours until I'm home from work to confirm.

Yeah, something like that or an 1142. I haven't decided on that yet, need to measure the heads. I think the one on hand would be a little too large however.

FYI he is calling the grind number 73353-75348 meaning it is closer to 292/233 than 277/231 I would think? I would assume that is the lobe it would be based on?
