Grimy Posted October 23, 2021 Share Posted October 23, 2021 I see 8 valves in the block and 4 probably-exhaust ports. Can barely see the rocker. Is this a T-head engine (2 cams in crankcase) with overhead intake valves? Link to comment Share on other sites More sharing options...

Mick, an F-head 4 occurred to me but there are *eight* valves in the block.....a F-head 4 would have only the four exhaust valves. Link to comment Share on other sites More sharing options...

Four of those 'valves' are pushrods to the overhead valves - are they not? 1 Link to comment Share on other sites More sharing options...

The valve spring and lifters on #1, #3, #6, #7 & #8 (as viewed from the front of the block>) all pass through the block and line up with the overhead rockers. Check out the thread pitch on those studs coming vertically out of the block just above that magneto/ generator/ waterpump/ distributor drive coupling! 1 Link to comment Share on other sites More sharing options...

Slightly different treatment around the spark plug recesses, but the general layout of the block and the various mounting points for accessories is dead-on.

paulrhd29nz Posted October 23, 2021 Share Posted October 23, 2021 That’s a 22 or 23. They moved the plugs to the other side (this motor ) in 21. It also has a timing chain not gears. As the early ones did. Nice score. They are a very fast and reliable engines. 1 Link to comment Share on other sites More sharing options...
