Re: measuring JE coated pistons

Putting together a 4.6 bore big block Chevy with JE nitrous pistons. They have coated skirts with two small windows to measure the skirt diameter. My standard outside micrometer has normal size ends and the hole in the coating is too small. And since this is a fairly large bore my calipers do not h...

Re: Mr Fueling.

I'd forgotten that Jon Kasse wasn't the first to route one cylinder's twin exhaust ports to different collectors. Also there appear to be anti-reversion bulges in the primaries. :-k

Re: Unequal IVO & IVC events

Bumps, did you notice this is not a pushrod engine? For an OHC bucket lifter, the bucket surface is the only possible lift reference. Dairy, yes the error should be the same degrees and direction for both events. Otherwise (in this case) the cam is retarded (or TDC mispositioned) and you must not be...

Re: Timing gear misalignment

I replied to a similar thread some time ago, saying that I had once been told that the 'cam forward' position was by design, so that chain tension can help keep the cam from drifting forward and affecting ignition timing. Besides, as long as there's at least thirty thous more distance between the ch...

Re: Fuel system architecture question (mechanical pump / filter)

Ohio, If your pick up is routed through the top of the tank, a leak at say half tank height would start sucking air as the fuel level dropped. Long shot possibility: if the problem develops only after the tank empties from a long run it could be a blocked tank vent. 2x re 3 microns on the inlet side.

Yes, if polishing is in the plan it should always be done before shot-peening.

Re: Straight through mufflers

...I'm having a round aluminum muffler made for it... You wouldn't want to run Bonneville with one. Aluminum melts at ~ 1250° F. and loses half its strength by 600°. Decades ago, I used a relatively giant 2" aluminum tailpipe on an 850 cc Morris Mini road race car. After one track session, it had s...

Re: Oil Smoke driving me crazy

Back in the 50s, my Dad rigged up an oil squirt pump that exited in the cast iron exhaust manifold. That was for tailgaters. Oh yeah, and preventing internal corrosion in the pipes . Years ago I was paging through a demerit points list for various driving offenses (don't ask..) and discovered an en...
