That link isn't working for me, its my computer.
During the 1940s tighter tollerances used at one of the GMs engine factories caused the old buick engines produced there to have roughly 20% more power and fuel economy than the same engine produced at the other engine plants.
When I put my diesel engine together I spent hours grinding out .018'' top, .014'' second and .015'' oil ring gaps on my engine, which is really pushing it on a turbo motor.
Tolarances on piston ring gaps like that will never come out of a GM, ford, dodge, honda, toyota, hyundai or kia factory.
Also floated the piston wrist pins with about a .001'' gap, as far as I know most pistons wrist pins are still push fit.
Then I went through 3 sets of main bearings to get the main bearing fit I was after.
Also ported the cylinder heads.
