I bumped my initial up from 10 to 16 and made a real improvement. Every other fill up I do premium 87/91 and gained power with no pinging. Just a thought..Some go higher till it pings and then back off by 2.
I keep trying to find a local "free slant". I know I used to toss them out, never was asked for one so I never kept them. I started asking last year, and almost to a person I get "I had one, but I tossed it 'cause nobody wanted it". sigh...lol.
C'mon guys Rod bolts are cheap, and is like first thing you would do to a slant if you were to rev it. New K1 rods, 2.2 pistons, shaved heads. Not all hot motors have 50 year old parts still in them. Anyone throw a rod at high RPM's here? when did it happen? I hear 5500 for a 225 is somewhat of a redline but we are not talking a long stroke 225.
Yeah I wasn't trying to be a smartass or call you out or anything but when I saw what you said I thought "oh jeez, that sounds like what a novice would read and call a plan and something a proffesional would read and call a guidline."
EDIT: I was on the novice end of the stick at one time btw...
Imagine how much more awesomely it would run if you CC'd the chambers and removed the appropriate material to have consistent compression between each cylinder. Not saying what you did doesn't work, or work well for that matter. But when you take you're times on these engines and do it "there way", "they" run better. V8 guys can get away with shaving x amount of meat of cylinder heads and make really decent gains out of it, but there engines are bigger. These engines, with there smaller discplacement can't hide missmatched parts or unbalanced CR's as well because they don't have the CI to do so.Oh chitt,that's exactly what I did and my /6 ran most awesomest !!!:violent1::violent1::violent1:

unless you welded and/or ground on each chamber to get even CC's milling wont make them even... just smaller... but you are very correct on have a correct number to run off of...

i dont completely agree with this as they have to mill the intakes and alot wont do that... they just buy correct pistons (which we dont have the luxury by cost) and a smaller CID motor would be just as effected by of CR or spring pressures or balance as a big CID motor would... its just the closer you can keep everything to even the less resistance you have to fight to make power...
