Cam Centerline questions
Sounds a bit small tome too. I am wondering if what you want to do is even possible on pump gas. Even 93. But WTF do I know? lol
I do know this. You want to pay closer attention to the intake valve closing point than the centerline, I believe.
Lol, you know enough that I don't take your advice or opinions lightly! The guy that had the shortblock before me ran pump gas, but that was with aluminum Indy heads and 65cc, he had quench to help him, and a huge roller cam. I am hoping to get it to be pump gasable (I made that word.), but I will mix if I gotta. If there was more than one E85 pump in a 25 mile radius I think I would go that route!
For the intake valve closing point, what do I need to pay attention to, exactly? Would closing later help ward off detonation?
I always gotta do stuff the hard way.
If pump gas is a priority then why not get the static compression down to a realistic number for iron heads? You're tying the cam builders hands & I'm betting the trade off power wise would be minimal.
I bought the shortblock assembled, I don't have the cash for new pistons, rings, bearings, balancing, etc. Just trying to work with what I got. Had I built it, I would have probably gone with dished pistons. Besides, this is a challenge and I am learning alot about what you can do in different areas to affect power and streetability. I am just making the cam builders think harder and work for their money :) I could probably open the chambers by unshrouding the valves more, etc, and get the compression down lower, but I don't know enough about flame travel or air flow in the combustion chambers to deviate too far from stock.
