Time travel

I´m exploring a couple of areas more or less unknown to me, Mechanical fuel injection and the very tideous project of bringing a set of heads to birth. Basically MFI is the only righteous FI option for "Mother" and my approach is to listen very carefully to individuals who has proven it´s functionality with time slips and speed performance, and Hilborn has been very nice and responsive.

The Heads is another story and it´s been going on for years now, right now I have all critical dimensions and patterns set and checked and then checked again,  I`m also self educating myself in the CAD world and it´s not my day job so everytime I get back to it, it´s days of finding my way around SEKE´s, cordinates and views. But now I honestly think it´s time to make some shavings. With some help from Karling Racing I got the cubes of Uddeholm "Alumek" in the shop a year ago and the last few days I found some time (loooong hours) to verify height  dimensions for the rough machining to get it started. I posted a pic with a original dimension head in a same size cube rendered like glass (yeah I know it´s b.s.) but the Winterbrew tasted well when all dim´s where in.The final product is all about performance and basically 5/8" taller than original heads adressing the limitations such as spring height, short grip for valve guides etc  and the capability in todays CAD very quickly reveals the possibility for slightly less valve angles as the valve seat is further down.etc, etc.

Any decade now and it will be done. and if you wonder about the choise of material it´s easier the first time with Alu.  and two very heavy chunk´s of a secret steel matrix in the shed.......

Planning for the mods

Canned the idea of hex holing the cam for the Mechanical Fuel Pump, and if driven by the cam it´s done differently, basically pressfit of a hex 3/8 bolt head. The way I have it now i will add a drive to the Generator pad. for good reasons,  pump will be in front of the engine rather than sticki´n out on the right side, and it´s logic when the intakes are on the left side with shorter lines etc, the cam cover will be left untouched.
The drive will be partial Morris Magneto H5 drive gears and flange and additional bearings/plate. Kind of a nice winter project. haven´t decided on the type of pump fitting yet, flange bolted or clamp I´ll decide after I got the drive design set. And sure a magneto would fit nicely but that would be another project when I´m satisfied that the mechanical fuel injection is the way to go.
