Problem with Comp Cams

No. I have hydraulics. This is the cam recommended to me from Comp Cams:

If you want to check on specs on the cam, look up a part number 31-218-2 on our website.

I'm thinking it may be too much cam - I'm thinking about it.

Reid,
If you don't mind,
what is your top RPM, your prop size, and what type of carb are you running? Where did you buy your SpeedPro cam? That cam you purchased appears to be still available. Did you also replace your lifters? Where did you get them?

The production of opposite cams are getting very scarce. The problem is not grinding but there is no one any longer casting the blanks .
Since PCM built the 123 transmison opposite rotation engines are no longer necessary in CC boats. They can change the shaft rotation in the tranny.
The issue of dual vs single pattern cams has always been a personal call. However torque is more important in tow boats unless you are turning over 5250 RPM., torque goes away while HP climbs, depending on the torque range of the cam. Bigger is not always better.

Jim,
I hope you and everyone else in the Correct Craft owners and fan family have had an incredible holiday season thus far. Our Christmas was great. However, bad news on the cam I gave you the specs for, as it relates to the firing order. It's also a 351 firing order cam unfortunately. And for that matter, almost every 302 4V marine engine after 1970 or so, shared the 351 firing order as a result of Ford universalizing (is that a word?) the parts bins. Many out there with 215-225 HP 302 Fords may have noticed that their engines have 351 heads to go along with the 351 camshaft. If you're not sure, just pop off a valve cover and you'll see the 351 stamp. This was a factory assembly for the marine based 302 4V engines. So do you have a Holman Moody engine, as I know mine have the embossed plates on the chrome valve cover but my 302's have the 351 firing order? My Interceptor 302 just had a decal on the valve cover which I've easily reproduced when I replaced the cam. I believe I have an extra set of HM valve covers with the 351 F.O. plate on them which I could pop off and send to you if you wish. Otherwise, you may be looking at a custom ground $$ cam to keep that firing order. Let me know if we can help you in any way.

I think H&M still grind cams. They still list in the Ford Racing Parts Magazine. As I recall the guy's name is Jimmy Tucker and he was around when Parnelli and guy's like him became famous with H&M engines. He also told me he was there when they put an H&M engine in a CC and tested it. He told me the "car" engine torque's force was the same direction as the Driver's weight and the boat planed at an angle. Back then the boats were smaller and narrow across the beam so a car engines rotation was definitely a "deal breaker".

Great guy, you should give him a call and talk about the cam grind. He helped me a lot during my re-build.

Jim, Good deal. I'm sure Jeff gave you a little crap about the "those backwards engines" as he always does me. Did you ever say which 289 Ford you had, whether it was a H-M or an Interceptor?


64 Skier: Regarding Holman Moody, and since I'm in the Charlotte, NC area and have a HM engine, I naturally went to them first, hoping to get something I could call a factory upgrade cam. I've spoken to Jimmy Tucker also; what a wealth of info- and to Larry Wallace who grinds the cams. Unfortunately though, and from time to time it bites us all, he said he couldn't get the reverse rotation cam blanks/billets anymore.    

It's an Interceptor, ReidP.

Yes I do, I am out of town right now, E mail me at wburg69@yahoo.com I am at a computer every day.
