I have a 68 Owens Flagship. The engines were rebuilt in the 90's. We recently overhauled the starboard side, which is the reverse rotating engine. Where is the #1 cylinder? and what is the cylinder order? What is the sequence for adjusting the valves, when I am up on #1? It Is a basic 350, but I can't find any literature on the reverse engine. |

You can look at the engine the same way as a standard rotation engine as far as #1 cylinder goes...firing order is: 12756348
Valve adjustment will be the same as a std rotation do it at TDC ( compression stroke )for each cylinder.....is it a hydraulic camshaft? or solid lifter? |

If the distributor is toward the front of the boat and I am standing in the back, looking toward the front of the boat, Which cylinder is the # 1. Where I got mixed up, someone previously labeled the cylinder to the right, and closest to the front the #8. That would mean the #1 would be on the left closest to me. And don't I need to get #1 up to compression stroke, then point the rotor toward 8? |

If the standard 350 engine firing order you have is 18436572 then the counter rotation engine should be 12756348. Note line up number one cylinder which is the same cylinder as on a normal rotation engine and wire the engine dist in the direction of dist rotation and with the second order I gave you. If you don’t have the dist in the proper number one dist location put your finger in #1 cylinder spark plug hole (Looking at the engine from the flywheel /dist end it would be the right front cylinder) and crank the engine slowly until you feel compression. When you feel compression look at the timing mark and continue to rotate the engine to 0 or top dead center on the timing pointer. This should be the compression stroke of #1 cyl. For now just put the #1 plug wire in the position the rotor is facing and follow the reverse order I gave you. This should get you close for now and the engine should at least try to start. Once the engine is up and running good you can change the dist wire position to the factory position by pulling and setting the Dist assembly and rewire the dist so it looks factory.
These are just my opinions I hope this helps.

Looking from the flywheel end of a Chevy the #1 should be on the left front, normally the drivers side in a car.
front
1 2
3 4
5 6
7 8

Darn I got all mixed up when I was explaining the correct #1 cyl side. Jb Castagnos is 100% correct. Do I get a do over for having a senior moment? Darn Darn Darn I only worked on Chevy racecars for 30+ years Darn!!!!!
My apologies for incorrect Data.

Number 1 to my knowledge is always the most forward cylinder opposite the flywheel. Or to state it another way the cylinder that is the fartherest from the flywheel. Small block Chevys as JB says its the drivers side. |

To set adjustable hydraulic lifters I tighten all of the locknuts to just take the play out of all rockers. Rotate the crank about a half turn or more and tighten the loose rockers, don't touch the tight ones. Rotate another half turn or so and recheck. The lifters should all now be at zero clearance. Tighten each locknut 1 round to center the lifters and install the valve covers. |

Well, thanks alot for the info. It worked out great. Although I dropped the distriutor in, rotor towards #1 when I was on the exhaust stroke. I gave up for the day. But I'm very close, and now know what to do, thanks to you guys. I'll keep you posted. |

If you've got the valve covers off watch the exhaust valve on #6, if it's opening #1 is coming up on compression, align the timing mark and drop the dist. If the valves are moving on #1 you're on the wrong stroke. |
