The plain truth is, I was sort of hoping that someone else would pick up my idea, cast off several, then I could buy one from him...What I will probably end up doing, is using either a plain 134L jeep flat head, (with an aluminium high compression head,) stripped of the cast iron manifolds etc.+ maybe 4 carbs, and headers. Or just bite the bullet and go with a 4 cyl geo and a commercial re-drive.I might just for kicks look into the aluminium block idea a little longer, as there are commercial foundrys nearby.ocb>From steve(at)byu.edu Sat Jan 2 18:43:23 1999>Received: from adena.byu.edu ("port 2144"@adena.byu.edu [128.187.22.180])> by EMAIL1.BYU.EDU (PMDF V5.2-29 #31181)> with ESMTP id for oilcanbob(at)hotmail.com;>Date: Sat, 02 Jan 1999 20:40:28 -0700>From: jmcnarry(at)techplus.com (John McNarry)>Subject: Re: engines>Sender: Maiser(at)adena.byu.edu>To: Pietenpol Discussion >Errors-to: Steve(at)byu.edu>Reply-to: Pietenpol Discussion >Message-id: >MIME-version: 1.0>X-Mailer: Microsoft Outlook Express 4.72.3110.1 (via Mercury MTS v1.43 (NDS))> (via Mercury MTS v1.43 (NDS))>Comments: Originally To: "Pietenpol Discussion" >X-Listname: >>Hi Oil Can,> I suppose if you could find a foundry to cast a few you might sell>enough to bring down your cost, but then it would probably be an expensive>process to machine and sleeve the blocks.
