What are the different LS1 style (4.8 5.3 6.0 5.7) head ccs? What are the average cc stock chambers are? Bout howmuch cna you take off of them decking them? i was wodnering what compression you could get down to with 6.0 heads on a stock shortblock, or how high with the 4.8s etc.

Re: What are the different LS1 style (4.8 5.3 6.0 5.7) head ccs? LS1derfull,
what quench height and gasket area are we talking about here?
The pistons don't have any valve reliefs so we much be talking about that area.
I was using a .040 qunech area on a 3.905 qasket.

Re: What are the different LS1 style (4.8 5.3 6.0 5.7) head ccs? can some one calculate stock bore and stroke, a popular size head gasket, LS6 heads, -10.00cc pistons, and 6.125 rods.

3.905 Gasket bore, .060 thick, .015 postive eck height on the piston, 64.5cc Chamber -10cc dish
BTW Rod doesn't have anything to do with it, if it's done right.

But I thought it it was a -10.00 cc piston it was dome, I went to an engine compression calculator a while back and when ever I put in a positive number it had low compression. I was thinking that with this set up I would get around the area of a high 11 low 12 compression ratio. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: What are the different LS1 style (4.8 5.3 6.0 5.7) head ccs? What he is saying if you go with a longer rod, you have to get a shorter compression height piston. SO the piston ends up in the same loation. Now you can move this around a little bit, but too far down and you lose quench and too far up annd piston meets head <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
your compression would be down at top dead center by 10-3=7 ccs that woudl end up about .7 points below stock whithc is what 10.1? so youd be at 9.4 or therebot liek brett said

Re: What are the different LS1 style (4.8 5.3 6.0 5.7) head ccs? so with a 6.0 head unported(70cc) 3.905 bore with Diamond 11503 FI piston(-8.6cc dish) and a popular FI head gasket and a 6.125 rod = what compression ratio?
Or the same as above but with a 11502(-2cc pistons)
= what compression?
I am putting a new engine together and this info would help me greatly.
Thanks,
J
