What I said certainly wasn't any dig at you. Only wondered how the latest that come from another OSO member that cams were fine. Honestly I didn't think they looked fine but pics did exaggerate problem or my iPad sucks. In regards to snakeskin or scale being ok I disagree with. It's not heavy enough to settle on pan bottom yet light enough to float around and end up who know where. Just wondering is a wider wheel would help this issue? Just surprised this is considered normal. Guess I ran a lot more hyd and solid flat tappets which in a sense would even out the pressure on the lobe surface.


How you looking for duration on new cams?

All good... stresseful day lol

40 years of experiance, I have zero doubts, and numbers show that..

with unstable valvetrain anything is possible, I did see another cam of a circle track engine with same wear, with lots of time, looked just like mine, as far as that goes time will tell in future.

New cams look to be in 248-251 intake duration and 254-256 exh duration, all 680 on 112... deciding still

You need to take a look at all your posts in all the threads you've mentioned your motors (not just your many threads)and see who tries to fight who, Gosh, you;ve even duked it out publicly with your own friends.

Why any of us still entertain you is beyond me. Give us some credit for that.Seriously.

Want my full answer now ?

For your boat:

565's
AFR 315's or equivalent
242-245 I at .050" 6-8 degrees more exhaust 112LSA
Vic 454R - 1050 Dom or extremely close equivalent 4150
KE Exhaust
And better drives.

Please don't answer with "this is what I have now" like you keep doing. I understand that and why we keep answering your posts and threads with what if's and etc.

getrdunn - I know what you are saying as far as head size, but...a lot of other's 320 heads on even 502-509's have done extremely well.....so I can't see why the AFR 325 vs AFR 305 would be such a slouch.

I'm not saying he did a bad job. I'm saying that unless there is a before and after to compare them and to also establish how his bench and testing methods compare to the flow numbers posted by AFR it is not useful information. Again, the heads might be great- it's just that the information isn't very helpful.

Truce. moving on.

Turn off computer, turn on wife unit.. Worry about right head and duration and day will be less stressfull....

Disagree, but that's what forums are for, that is like saying a dyno is a waste, in the end, I have flow numbers that were done on the bench my guy uses for ALL his engines, a head guy with 40 years of hand porting heads, and not magazine flow numbers, I am ok with that, bob spec'd cam with none of that... I am willing to accept the results this time
