Humm...
Considering your distributor is 24 deg all in, most are. Then plus the 10 that's 34. Which in my humble opinion is pushing it in a marine application. Your hotter than normal cam may give you some headroom but I bet your compression is higher than normal (for a boat motor) also. I would go for 32 total to be on the safe side. Detonation you cant hear will hammer holes in pistons in short order under continuous loading. MarkW |

Andrew: Standard timing for an early 1960's 327 @250 HP is 4 degrees BTDC, 8 degrees BTDC if the engine is rated @300 HP. However, that assumes you are using leaded gasoline. Without knowing the lift and duration of the cam, I'd say starting at 8 BTDC would be a safe bet but I'd still watch the tach under load @3500 RPM and set the timing to peak the meter. If the valves begin to ping, back off the timing until the pinging stops. That will be your final setting, whatever it turns out to be. Naturally, you'll want to stay away from gas with ethanol.

Test run #2 is in the books. Absolutely no leaks of any kind and the shifter performed as it should. I'm still not happy with the Comp Cams 268H, I regret installing it now. In fact, I am seriously considering pulling it out and replacing with the a 350 horse 327 cam. I've used this cam many time and have always been happy.
So far, so good with the 800 series stringer. After both trips (short) the drive is still full of oil and no water intrusion. The hull of the Johnson Deluxe is remarkedly stable. This boat rides, turns, and crosses wakes without any lean or sway. The ride is just like a car, in the water! I love it!! Plus, there isn't anything on the water like it. The lakes are full of cookie cutter boats and the Deluxe catches everyones eyes.

why are you not happy with the comp 268H? the 350hp/327 Duntov cam is a good one,and always performed well for me too. skipp

Hey Skipp! The big trouble for me is when I lower the initial timing below 18-20 degrees, I have to turn the idle stop screw in to keep it idling at 800 rpms. Turning the idle up that far exposes the transition slot in the carburetor. This pulls fuel out the main venturi and floods the engine. The only way I have found to prevent it is to keep the timing set way up, 20 and higher. Too dang high in my opinion. I believe the 268h would perform flawlessly in an engine with vacuum advance. |

The most modern flat tappet cams out there are these Lunati VooDoo's
www.lunatipower.com/ProductGroup.aspx?id=287&cid=58 The 701 has a very slight lope to it in a 350. But even the 700 is going to be overall better than any old stock GM cam. The required mechanical advance is going to be a limiting factor. That and the rpm limit to keep a marine engine from having a short life limits your cam choices. Be sure you run oil that has zinc in it so your flat tappets will live. Rotella T synthetic 15W-40 is a fave around here. IIRC the BTDC of a GM 350 Mercruser 260hp was 10 deg. |

The point about the Zinc is something new to me. I had not realized that modern motor oil had removed that important part that flat tapped cams need. I will going to the rotella asap! Thanks for sharing that info.

Yea I think the EPA hippies want to destroy all the older pre roller cam engines.
It would be super to go to a roller cam, but big $$$ if your block is not milled for stock style roller lifters. When we say 'Zinc' we really mean the whole anti scuff package that its part of. Shell Rotella T 15W-40 is a great oil for heavy duty use in gas engines. It comes in full syn and part syn. The general consensus among the gear heads, is that full synthetics are good enough not to need zinc to prevent galling AFTER break in. Mineral oils always need zinc to prevent galling during operation. Both need break in additive (lots of anti scuff stuff) during break in. The flat tappet cam is the most vulnerable part during break in. I have seen this dramatically with high spring pressure racing cams. If you didn't use the additive (from the cam MFG) and break them in with a 30 minute period of high idle (~1800). They might not last an hour. Its a crap shoot how long. If you broke them in right, then they would be the last thing in the motor to go. I used this stuff with my last flat tappet cam build. Came highly recommended from the local hot rod crowd. lucasoil.com/products/engine-oil-additives/engine-break-in-oil-additive-tb-zinc-plus Also its great for regular use. The owner splits one bottle between the two engines every change and uses Rotella T, belt and suspenders approach.  |

Huh, great information for these older engines - thanks! This should be a sticky someplace, like the I/O gallery or something.

Two videos for your viewing pleasure. The first is the Comp 268h camshaft....
The second is the bone stock factory 327 camshaft... Here is the big difference, the 268h consumed 5 gallons per hour @ 2300 RPMS The stock cam consumed 2.5 gallons per hour @ 2300 RPMS!!! I honestly could not notice any lost in power. Idles good, come out the hole fast and strong, and pulls like hell. |

That's a no brainer then Andrew, 'cause she still sounds pretty mean with the factory bumpstick! Good job sorting that out, and with gas prices going back up you'll be happier all the way around.  |

Andrew, looks like you guys had a blast. You're really making me miss my Rogue II....can't wait to go back to Texas to get her and the CJ-5.
Speaking of Jeeps, I'm a member of the jeepforum.com and we have discussed using Rotella 15W40 ad nauseum. It truly is the best oil to use in these old engines and will provide the zinc they need. I friggin' hate the EPA. Which reminds me....I can't remember if it was Car & Driver or Road & Track, but one of those two rags did an emissions test around 1991, using a Saturn LS on unleaded gas and a fully restored 1970 LS6 Chevelle with leaded....the Chevelle burned cleaner, even with the monster 800cfm Holley 4bbl and a points distributor. I know, people not keeping their engines tuned is what led to the EPA making these rules, but I still don't like them. The boat looks great. |

Here I sit with three boats and never got on the water yet this year. Thanks for sharing what it's like.
4th of July is not a weekend I want to be out either, too many crazies. Fredric. I am a member of the JeepForums also but haven't been on there for over a year. Had a '98 XJ with over 342k and running strong then rolled it...total  Picked up an '05 Liberty and never had any issues. Been over 1 1/2 yrs now. |

I am pleased to report we had an awesome summer in the Deluxe. Logged more than 30 hours cruising and pulling the kids. Must had gotten a hundred comments and questions about the old girl. She is winterized and ready to begin off season improvements.

Glad you shared your experience with all us. Learned a lot. The old tri hulls are not that popular in my area but I've never had issues with them. very solid and stable, really over-engineered. Have a great off season.

We have had another great summer on the lakes with our 1964 Johnson Deluxe. This old boat is AWESOME! She romps around the lake and you can't believe the attention she gets. It's hard to ski or swim for the people coming up to take pictures and ask questions about the old girl.
Here is a link to a video from today and a few pictures.

Andrew,
Incredible job on the Deluxe. Sounds so good when you open it up! I've always loved this design. Picked one up in 2009, but decided that there were too many other boat projects ahead of it. Sold it to a guy who shipped it to his brother in Denmark. The brother posted a short youtube video of his renovation. It seemed like the floor was solid when I had it, but the brother mentions he pulled 900 lbs of wet foam out when he pulled the floor. I think your motor set-up was the way to go. The original 88 hp OMC v-4 did not have enough juice for this hull. Congrats on another great summer in the gullwing! Paul |

Thank you so much for the compliments.
I have followed the rebuild of that boat on OMCBOATS.ORG for the last couple of years. The floors in these boats feel solid because you standing on the wet foam. The wood is only 3/8 on an inch thick and will be rotted away under the glass. Mikkel has done a wonderful job on his Deluxe. |
