'77 heads had bigger chambers (67.5-70.5cc) yet compression ratio increased from 8.0:1 to 8.4:1 by use of taller pistons...
: I was referring to you saying the combustion chamber size, 62cc will put the 74s down to 7.*. explain that. were the castings that irregular?
: who's the one that needs to think? you need to read the whole thread, its in your friggin title that I'm asking about. duh.
: oh, and I didn't say anything about a "book"... I was beyond the basics about 6 years ago...
:
: : That's like trying to explain the theory of relativity to a third-grader...Valve sizes have NOTHING to do with compression ratio...Look it up in your "book" ...If you're gonna argue with someone, it's a good idea to know what the heck you're talking about, don't ya think??...Learn the basics first & then come talk to me...
: :
: : : then the 74 compression ratio is more like 7.7:1.
: : : explain it better than that, that's the only problem I have with you, you tell stuff and don't explain it. it takes 3 posts to get the information outta you.
