I picked up a old chris craft 390x for a decent price but one of the engines needed gone through. Im putting back together now and found out they no longer make the cam i need to match to the other engine. Im wondering if I should just try to find one close to what i had, or have one specialty ground?

Im really not wanting to put a lot of money in these engines, because they are getting on the limits for specs , internally. Plus I have another 2 engines i have been slowly putting money into to replace them engines.

It's probably going to be cheaper to run something "close enough" than to pay for a custom grind. A few hp difference per side shouldn't be all that noticeable.
