Just an update. This motor is now running and I cannot believe the torque this thing puts down. I have had a lot of fun this weekend putting it through some heat cycles. I have changed the oil and pretty much no shavings. Nothing more than a few small, normal specks from the break in process. I haven't really opened her up yet, but I seem to have pretty nice build so far. Dyno time will be coming this week. I'm not gonna make any hp claims, and don't think I'll hit 60, but at least I'll have a good base to build upon.

12)All with Ti in middle
13)Proto super light Ti spring

Porting was only $75.Not alot done but everything matches.Thought would be more since $ was no object but never know.Chamber was extensivly reshaped.

Valves are not coated.

Springs inner/outer are interference fit like kibblewhites.Must be bigger dia.buckets are tight on them as are the retainers in inner spring.No washers spring seats are a bit thicker.Also new along with guides and seals.Guides are longer.Will have to call but I believe the lightwieght spring is what we are trying next.Should be fun.


Ever wondered how hardened seats are removed?Here are stockers.
