I'm using that cam on a 496 stroker with gil manifolds. It's on the ragged edge of reversion with short risers. I advanced the cam a touch, the EVC event was too late straight up. You must degree in that cam and give it about 1* if you want to use it with short risers.

Do you have anymore info or a video of your motor? Your the first person ive come across using this cam. I think i may just go ahead and lengthen the 496 risers while its apart based on your post.

I did the build, minus the machine work, myself. 454 .060 over, 4.25 steel crank, 6.385 rods, probe 18cc domed pistons, 049 heads (twins to 781s) ported and polished with 2.19/1.88 valves, comp springs 134# seat pressure, scorpion full roller rockers, Howards cam/roller lifters/custom length pushrods, eddy rpm air gap (switching to Vic jr), fast ez-efi, gil exhaust from a HP500.

It's a stump puller, but it signs off a little early and falls off a cliff after 5k. I'm going to switch to long or dry trails and run a larger cam. I'm leaving at least 50hp on the table with this cam, especially having it advanced.

**edit in** It is a 93 or better only engine with that cam and 10:1 static.

thanks a bunch man. its ridiculous how close our combos are. hopefully great minds think alike. what boat do you have and how fast is it?

im going to install the cam "Straight up" im wanting to spin around 5400.

That cam, even straight up, will run out of steam before 5400, peak torque will be closer to 5000. Mine is in a Crownline 225CCR which is not a fast hull at all and hits a brick wall at 68mph. I can spin a 26p on the limiter, 68... I've spun a 30p to 4700, 68 with a ton of slip. A few others have put decent power in these boats and say an extension box pushes the wall up to the mid/upper 70's, but after that it's just a black hole for hp. Keep in mind, though, it was a 53-55 mph boat with a 330, so it was a pretty big gain for a crap hull. I'm currently plotting against my wife on how to pick up a fountain or similar without her calling a lawyer. I may need a partner in crime to fudge the numbers lol...

Buy the Fountain and put Crownline stickers on it. Hopefully she doesn't notice ! ha,ha

I think the boat taking up 7 more feet in the shop would be a dead giveaway. Funny how she says they all look the same but can somehow tell when I have a different prop mounted. Seriously, she walked out and said "That looks different, how much did that thing cost?" WTF? She also knows to take whatever number I give her and multiply it by at least 3... Somewhere, sometime, somehow, I slipped up....
