chris11 184 #1 Posted March 2, 2014 Hello all, A lot of you guys know I have been sick. I have been Battling cancer and been doing good with it. Its giving me a chance to think how short life is. So I Want to build a Hot engine for a project im working on. I was going to build a k341 Kohler, started picking up some parts. Like everything I do for some reason I have to go over board. Well I started with a stock block. Picked up a used crank stroked to 3.75. Then I find out the engine I wanted to build you cant use stroked crank, and the max bore size was only .030 bigger then stock. The more I looking into it I wanted MORE. So I have collected some really nice bunch of parts to play with. Im not using the stock block. I picked up a J2 after market block Very HD. 10,000 all day Billet cam with a .625 lift, billet rod, and piston. The stock size was 3.75 bore. The new bore is 4.125 and I have still more sizes I can do. The crank I found out wasn't as good. so I ended up buying new, Billet crank . 3.75 stroke. The engine building thing is so many ways that guys do thing , no one will tell you anything, as far as port size angles any thing. The block I have I have to machine ports lifter holes center lines aren't the same as stock. so im working everything thing out 3 time before I do anything. here's some pictures of the parts I have so far. 5 Share this post Link to post Share on other sites

Flatheadpuller 6 #6 Posted March 2, 2014 Chris not sure your machining capabilities but I know a couple guys that can help you if your interested. I also know of a complete 50.5 that is in the 71-73hp range on alcohol that is for sale. Really good price. far less then what your going to have into what you have to make 70hp. 1 Share this post Link to post Share on other sites
chris11 184 #7 Posted March 2, 2014 I can machine Anything. And I never say no for help. pm sent 1 Share this post Link to post Share on other sites
chris11 184 #8 Posted March 3, 2014 Well I have tested crank fit and got the end play I need. Next is test fitting the cam. setting cam ever in there I have to grind a little spot on the block opening. I always try taking from the block and not the parts. Now cam and crank fit . I can make the side shim I need for cam centering in the crank . Because of the stroke the rod has to be right in the middle. Share this post Link to post Share on other sites
chris11 184 #9 Posted March 3, 2014 (edited) Next step is going to be setting up to bore block and cut rod reliefs at bottom of cylinder. You can see it this picture that I have to locate where lifters have to be centered in the cam shaft lobes. But need to test rod into block to make sure rod isn't going to hit lifters.

Deere Hunter 54 #10 Posted March 3, 2014 (edited) Chris, You will probably have to clearance one of the crank throws also to clear one of the cam lobes. Not sure which one, its been a while since I had the pan off my Pro/Super. Was the cam matched with the stroke you are running? I have heard with longer strokes it limits the lift of cam you can run, because of the clearance issues. Edited March 3, 2014 by Deere Hunter 1 Share this post Link to post Share on other sites
chris11 184 #11 Posted March 3, 2014 I had him make the cam to my stroke. Im going to bolt the weights on and check. Didn't do much with it today. I am using 1.5 lifters so I know they have to be cleared. 1 Share this post Link to post Share on other sites
chris11 184 #12 Posted March 5, 2014 Heres a few more parts.Big valves and bigger base lifters for the cam. 1 Share this post Link to post Share on other sites
Jim_M 178 #13 Posted March 5, 2014 What size valves do you have? The exhaust valve looks small but maybe it's an illusion. 1 Share this post Link to post Share on other sites
chris11 184 #14 Posted March 5, 2014 2.00 and 1.625 Share this post Link to post Share on other sites
Jim_M 178 #15 Posted March 5, 2014 (edited) By today's standards that's a little small. I'm working one one now for a friend. I had to offset the valves to get them to clear each other. Only about 3/4 of the valve stem sits on the tappet adjusters with the amount of offset they had to have to make them fit. I plan to modify the tops of the adjusters so the whole stem hits it before I go too much further. He had a 2.025 intake and a 1.650 exhaust and they weren't big enough.
