I think I have heard them reffered to as 1050s. I have been building a few and they make a nice unit.
I use an A+ block and the late 998 press fit rods and flat to 10 to 1 pistons. Bore , clean , hone , deck
, cam bearings and freeze plugs. Grind or polish the crank and balance the complete assembly. I use
two part Cooper balancer and light flywheel and back plate. If using a 940 cyl head I relieve the block for
exhaust valves and drill and tap for extra studs. As long as I can get them I prefer to use the Cooper/
1100 295 cyl head castings. I use cast valve guides, hard exhaust seats, O/S late lead free triple groove
intake and exhaust valves. Head needs to be CC ed and a pretty good wack surfaced to reach 10.2 to 1.
I built one for a customer and used the Swift SW5 cam. The next one I build will get a Kent 266.
I have to use four different machine shops to get all my machine work done. The only shop who bores
small bore is an hour drive each way. The last 998 I did I ordered two sets of pistons and a couple of
sets of press rods. I had two blocks roughed out. I also had a second 295 cyl head done at same time.
All it needs is honing to finish size, balance and order a cam.
If someone needs nice 998 for a summer project let me know. Steve (CTR)
