Neat Trick!! I think the pairings listed are wrong, though (or maybe I
didn't get enough sleep?). Pairs should be opposite in the firing
order; for the 1-8-4-3-6-5-7-2 order, I think the pairs would be 1&6 -
8&5 - 4&7 - 3&2. The 235's firing order is 1-5-3-6-2-4, so the pairs
would be 1&6 - 5&2 - 3&4.

Subject: Re: [oletrucks] Adjusting valves
The easiest way I know for finding out when a cylinder is at TDC
ignition stroke is when it's opposite cylinder is "on the rock" (I'm a
Brit, you may have another term, it means that both valves are slightly
open, valve
overlap) both push-rods are "tight", under pressure. To establish that
no 1 on a V8 is on TDC ignition, No 7 cylinder is also on TDC but "on
the rock"(the push-rods won't turn easily).
N01cylinder tdc->n07cylinder"on the rock" adjust N01cylinder
N02tdc-> N08"on the rock"adjust N02cylinder
N03tdc-> N05"on the rock"adjust N03cylinder
N04tdc-> N06"on the rock"adjust N04cylinder
N05tdc-> N03"on the rock"adjust N05cylinder
N06tdc-> N04"on the rock"adjust N06cylinder
N07tdc-> N01"on the rock"adjust N07cylinder
N08tdc-> N02"on the rock"adjust N08cylinder
This is for a firing order of 1-8-4-3-6-5-7-2
Does this make sense?
