But, there are things you can do to a Healey engine to (marginally) improve performance and reliability without changing the essence of the car. Here's some of the things I did for a recent rebuild:<o:p></o:p></p><p><o:p> </o:p></p><ul type=disc><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>Denis Welch DWR1 cam. This cam is 'slightly better' than a stock BJ8 cam, and is gun-drilled to provide extra oil to the lobes and lifters<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>84.5mm Omega forged pistons. Way overkill for a street engine, but I couldn't find 'out-of-the-box' pistons that were of sufficient quality with 'modern' features like the 'latest ring design'--the top ring is about 1/16" thick!--from any of the usual suspects. My builder was impressed with both the cam and the pistons; the pistons were not much more than half the weight of the older, more-or-less stock pistons, and the cam was of extraordinary quality<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>DWR high capacity oil pump with upgraded shaft (DWR sells this shaft and thrust washer for about half of the 'usual suspects,' esp. with the favorable exchange rate)<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>adjustable vernier timing set. My builder said it took almost 4deg to dial in the cam perfectly. Timing set is of excellent quality.<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>fully engineered PCV 'system.' Still just sucks gasses from the crankcase, but my builder designed piping to equalize flow to both carbs, and I can run K&N filters without modification<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>instead of cork and fiber ('cigarette') gaskets, my builder used a modern sealant ('Right Stuff') to seal the rear main, engine plate and pan. Several hours on the test stand and 'hasn't leaked a drop'<o:p></o:p></li><li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1'>Jet-Hot coated exhaust manifold. I believe ethanol-blend fuel was causing some stumbling on hot starts and I'm hoping this solves the problem<o:p></o:p></li></ul><p>I have some video of the engine running on the test stand (LARGE files), and my builder wrote a detailed list of all the work he did to make a strong and reliable street engine. If anybody's interested I'll scan the list and post URLs to the video, but I can't do it until I get home Saturday.<o:p></o:p></p><p><o:p> </o:p></p><p>Bob<o:p></o:p></p><p class=io-ox-signature>--------------------------------<br>Bob Spidell - San Jose, CA<o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-bottom:12.0pt'>On March 2, 2017 at 6:07 AM 1 2 <<a href="mailto:healeydohdahman@gmail.com">healeydohdahman@gmail.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='margin-bottom:12.0pt'>Hi All,<o:p></o:p></p></div><p class=MsoNormal>Is there a list of commonly done rebuild mods for the 3000 engine/transmission to modernize it?<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>_______________________________________________<br>Support Team.Net <a href="http://www.team.net/donate.html">http://www.team.net/donate.html</a><br>Suggested annual donation $12.75<br>Archive: <a href="http://www.team.net/archive">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums">http://www.team.net/forums</a><br><br><a href="mailto:Healeys@autox.team.net">Healeys@autox.team.net</a><br><a href="http://autox.team.net/mailman/listinfo/healeys">http://autox.team.net/mailman/listinfo/healeys</a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/bspidell@comcast.net">http://autox.team.net/mailman/options/healeys/bspidell@comcast.net</a><o:p></o:p></p></blockquote></div></body></html>
