I've been putting together this 7.3 turbo engine for a Centurion that a bought a few years ago. The covers are at the powder coater, And I'm changing the cam with one from IDI performance.
A few questions.
1. It's a Jasper engine, and the numbers are ground off next to the injection pump. Jasper put their own numbers on, so I don't know if this is a factory turbo block or not. Is there any way the check? Differences between the NA blocks and turbo blocks?
2. The lobe for the fuel pump is gouged, not bad, but enough that I noticed. Will this cause a problem? Is it even possible to get the lobes anymore.
3. When changing the valve springs with the 910-16 Comp Cams springs that the guy at IDI performance said the cam needed, I noticed that some of the springs has a .040 spacer under them. I've removed the spacers, and installed .060 spacers under the exhaust valves only. Were the original springs just a little old, and that was the engine builders attempt at compensating for worn springs? I had the heads machined and done a year ago.
