Hey Guys, I've been back at it on my truck and I'm doing the brake system. I bought a new master cylinder and I'm wondering what fitting I need to come off the end of it? There isnt much room there and it needs to turn. I must have scraped or misplaced the original MC. Any help would be appreciated. I'll have to put up some pictures of my progress. Also my original fuel tank is in pretty rough shape (holes rusted through in various places. I was going to cut it apart, clean the inside, patch the holes and line the tank, but it might be more cost/time effective to just put a new tank in) any body make a repop or replacement of simular dimensions? (I havent done much searching on that yet) here is a link to my blog with a few... http://donorcycles.blogspot.com/2016/01/dodge-duck-dip-dive-dodge.html

I measured mine with stock valve lift and only a couple thou off the head figuring with a .075" head gasket and I didn't have a ton of room. I wrote the figures down so I'll have to check tomorrow but I'm pretty sure I couldn't take .090" off the head. .060" intake, .090" exhaust is kind of a common rule of thumb for valve to piston clearance on a steel rod engine. Obviously you can get things a little tighter in a flathead configuration.

wow you are really doing a great job on this thing! & hauling ass it appears!

Got some more done today. Installed the Oiling system with a new pump. Got the Oil pan all buttoned up. When you guys do the first initial valve lash adjustment are you setting them at .010" for intake and .014" for exhaust? I know I'm supposed to reset them with the engine HOT.

I did some more work on the engine today. You can check out all the details on my Blog http://donorcycles.blogspot.com/2013/03/shes-spinnin.html

When you get into town Merle you'll have to look me up. I went to school with some Coggins'. Sarah, and there was a boy too I think, but they were both older than me.

So I did some port work to this thing. Mainly I enlarged the inlet ports to 1.600" to match up to a CV carb. I am going to run three of them on this engine, & build a header for the exhaust. Maybe a 6-3-1 or something. I have to get the engine all back together & in the chassis to see how much room I have to package everything. I started on the flange today. Hopefully get some holes drilled tomorrow

Yah I live in Plainview and I work at the Harley shop in Rochester. This truck came from the Red Wing area. It must have been stored in some sort of shed/leantwo for awhile because the seat isnt all cracked/rotted. The drivers door is all rusted out on the bottom and the passenger is starting. Otherwise the rust isnt too bad, dont get me wrong, everything is rusty. lol. just not rotted out.

I have installed them all with the counterbore down. My original service manual said nothing about running the counterbore UP on the exhaust side. It does have a special NOTE to run the counterbore down on the inlet side. I am pretty certain that the original guides I removed were all counterbore down too??

One of my questions off the top of my head... Are there any taller gearing options for the stock rear end?? So I can run with modern traffic. Or am I better off to put a different rear end under it?

The engine was stuck (one cylinder stuck, but 6/7 valves were stuck in the guides too). The truck has 43K miles on it. I'm just going to get it all mechanically rebuilt. Not going to do a full restoration. Going to spray everything underneath with Chassis Saver and drive it. The oil pan had some pinholes rusted through the bottom, so I repaired it. Installed new valve guides. The photo in the above post is my son machining out the old guides. Replaced some cracked seats.

Hey Guys, I joined this site last fall but havent spent a lot of time on here. I bought this truck in the fall of 2011 for $300 from the orignal owners nephew(original owner is dead, his nephew is probably 70 years old). I have been slowly chipping away at it. The truck sat since 1973 and is in pretty fair condition for a Minnesota vehicle. I'm starting to pick up steam now. I'll have the engine all buttoned up here in the next month and when the weather breaks I'll start working on the chassis pretty heavily. Hope to get it on the road sometime this summer. I'm sure I will have some questions along the way. I post updates on my blog from time to time. http://www.donorcycles.blogspot.com I'll try to update this too. Between raising 3 little kids, working full-time, chasing my wife around and riding motorcycles I stay pretty busy!
