Not Ranked
Guys,
For your FE's, especially running solid / flat tappets, see Crower's comments (literally) below. They're not big on synthetics:
Use of Synthetic Oils
Crower does not recommend the use of synthetic motor oils in any racing applications, particularly hydraulic and flat tappet camshafts. The minimum gains in horsepower are offset by the excessive wear to cam and lifter surfaces. Crower recommends Kendall GT-1 (20W50) Petroleum based motor oil in all high performance applications. If your manual suggests running synthetic oil, then do so. We have found, however, that the benefits do not outweigh the costs.
