Checked and rechecked my F-1 got 17.3 highway. I had a stock 302 with an Elderbrock 650 and a 2.73 rear.

Now the dream 20.

I have reworked the F-1 for a highway driver and think we may get near the 20 range, To do that we reworked a 302 with a mild roller, extensive head reworking, still using the Ellderbrock 650. A friend with a Nascar team with the software ran the numbers and we should peak at 315 horses. I added an AOD and kept the 2.73 rear and added a bed cover. Interstate sppeds should be in the range of 16-1700 rpms. We think that we may see 20 on the highway. Who knows flight testing starts the end of April, news at 11:00.
