Basically the Comp cam is not real efficient.Loves302Chevy - My car is 75% street, I set it up with the intention of not being a daily driver and more of a weekend warrior. It sees no more than 3000 miles a year. I drive it to work a few times a year, cruise around on the weekends, and put it on a trailer it if I want to go to the track. That way if anything were to break I don't have to come up with a plan "B" to get to car home from the track, which is about 50 miles away.
I agree that my cam selection was more "RACE" than "STREET", I didn't look at it that way at the time though. I planned to run a dedicated hydraulic roller but when COMP recommended I run this setup instead I changed my plan. They said given the tight lash specs of the profile I could run hydraulic lifters without issues. I assumed that I would be getting the best of both worlds: more aggressive cam profile (=more power right?) but not having to run solid roller lifters on the street (=more streetable right?). In the end I had more questions than answers regarding the efficiency and durability of my cam choice and felt I left usable power on the table.
Maniacmechanic1 - Once I got over the initial "awe" of spending a day at the dyno (my first time) I was disappointed by the lack of some information on the dyno printout. It's cut off the picture but the VE is listed to the right of the BSFC, the numbers all read 0.0 so I didn't bother to include it in the picture. Also - I recently looked at around 15 other random dyno printouts and noticed that the BSFC numbers seem to be between .3XX and .4XX on average. I see that mine are quite a bit higher between .6XX and .7XX, what do the higher fuel consumption numbers indicate?
It wants to be a race cam but falls way short.
There has been issues with Older SBC OEM blocks here lately that have been in use by members for years.....they finally gave up the Ghost.
