Need a reverse rotation cam

I would have put this in the wanted section but for some reason i cant post there.
I'm looking for a reverse rotation cam for a 454. The cam that uses a gear instead of a chain. I'm looking for something besides stock (I have one already). They are so limited that I will work with what ever I find.

I have a crane 741 reverse rotation cam (hydraulic roller) with dist gear. It has approx 100 hours on it.
This uses a chain and stock dist.
The firing order is reversed

I removed it when I went to SSM6,s.
Dont know if you could use this.

if you use the cam that used the chain you MUST use a specially made EST dist or it will eat distributors in no time at all....went thru 4 before we figured it out....Rob

I thank you all but I am trying to use what i have because i have to build a normal rotation motor the same exact way so roller is out. Something that will work with a cam gear.Or the basic Mercruiser reverse rotation 454.

Unless you have them custom groud, I'm 99.9% sure you'll never find anything.

Thanks.
I was making that call tomorrow. Just wanted to check to see if anyone had something sitting in the garage.

well as all reverse rotation engines were inboard boats, finding a H/P version not likely laying around as it would have had to been a custom grind...Bob's the man you need

I figured as much but had to ask. Just didn't want someone coming out with, "I have one of those i would have gave you" after the fact. Anyone have any idea what Bob would charge for something like what I need?

Thanks
