mrsmackpaul Posted February 26, 2023 Share Posted February 26, 2023 I wonder if that is 4 valve motors only ? Paul 1 Quote Link to comment Share on other sites More sharing options...
Popular Post mrsmackpaul Posted March 14, 2023 Popular Post Share Posted March 14, 2023 Well my books arrived and I believe we are all slightly wrong here, no offence meant to anyone Well the book once proof read from Miss Molly Tells me that Dynatard motors, engines for the sensitive types have different heads with a recessed exhaust valve So after a quick glance at the book I can see that one thing is obvious that is mentioned but not in a big way is timing It says to just line up TDC off the indicator on the front the motor indicator Now me been me and knowing that this indicator is only a indication would mean that possibly a few degrees off here and the whole shooting match is tits up So thinking a little more about this You can get offset key ways to line car motor timing up when building high performance motors Now thats on precise machined parts, not a bit of tin pointing at a balancer So Im wondering if TDC should be proven first to see just how accurate this indicator is Now a little more If only a Dynatard cam is fitted the motor would be retarded the whole time so it wouldn't run, the book says this as well So with this new found knowledge quite a lot can be learnt Timimg, valve clearance, good hydraulic lifters or hydraulic lash adjusters as the book calls them are important Not the things I was thinking of, good lash adjusters that aren't worn good rocker that don't leak oil out the rocker shafts All of these thing might only make a slight difference but combined might make a huge difference So now to find that elusive time for some experiments I do believe it might be a very plausible thing that some are as good as Jacobs and others are useless like mine Paul 1 2 Quote Link to comment Share on other sites More sharing options...
