FINALLY got some rainless weekend weather here in central Mississippi. Took the Ranchero to a small local track east of here for test and tune Friday nite. Ist runs with the new FE Power intake adapter and Yates 351C intake. I also phased the MSD distributor (adjustable rotor)and added one step colder NGK spark plugs. Other than these three changes the engine is exactly as before.
Prior to these runs Friday nite, the best time I had ever run was a 6.80, and a 6.85 and that was in the evening on a well prepped track back in early March. The other runs in March were all 695s averaging 1.55/1.60 60 ft.
The First run Friday nite was a 6.83, 1.49 60 ft, 100.34 mph, 2nd, 6.81, 1.499, 100.57, 3rd was 6.86, 1.47, 99.15 (with a 200 lb passenger), last was 6.797, 1.486, 100.78.
The miss I had from the last outing where I over revved the car is gone. I suspect it was a combination of sparkplugs, crappy MSD cap, and rev limiter set to low (Thanks Blair)
The track wasn't prepped at all and got so wet later I put the car on the trailer. I'm very happy with the improved times and believe that the car is capable of more. I'm still learning how to drive the car and seem to be making small improvements with regards to consistency.
I was concerned about the 60 ft times with the single plane intake but got my best 60 ft times ever. The car just felt different. I want to thank Jay for his help. I'm very happy with the intake and adapter and the excellent service I received.
I just ran the valves in preparation for next weeks race and they were all good, along with the rockers and pushrods. I guess I'm ready and very excited.
If I could just get in the 6.60s, Id be happy and quit buying race parts......
