DaleMX Posted June 25, 2006 Share Posted June 25, 2006 Hey Grumpy chime in here please, and any other onlookers, here’s my LS6 stroker plan. I am trying to achieve the ideal quench and DCR for my cam. I am thinking about a bigger cam though to keep my quench right and still be able to use –2cc flat top pistons. Bore @ 3.905 (being done next week) Gasket bore is 3.945 Stroke @ 4.00 The pistons are flat tops with valve relief’s at 2cc (or 7cc as shown below) The block is being decked so I’m guessing that the pistons will be out of the hole about .010 or maybe .015 (My stock LS1 was at .005 out of the hole.) Gasket is about .053 thick compressed Heads are 63cc + ring land volume of .99cc for a total of 64cc T he cam’s duration at .006 is 280 intake and 277 exhaust (230 and 224 @ .050) The lsa is at 111.1 That brings the Static CR to 11.51 If the calculations for the Dynamic are correct then I’m looking at a DCR of 8.75. This also includes a quench distance of .043 Over at LS1Tech I see that the LS1 like’s a quench of .030 - .035 and a DCR of 8.5 to 9.0. So if I run a .040 gasket and go with a –7cc dish piston that gets me a Static of 11.1 and a Dynamic of 8.5. If I run the .040 gasket and go with a 285 cam and the –2cc pistons I’m looking a Static of 11.89 and a Dynamic of 8.75. Any thought’s on this?

powershift Posted June 26, 2006 Share Posted June 26, 2006 are they considering that 383s these days? 383 is 4.030 x 4.00 no? Quote Link to comment Share on other sites More sharing options...
DaleMX Posted June 26, 2006 Author Share Posted June 26, 2006 are they considering that 383s these days? 383 is 4.030 x 4.00 no? No, 4.03 X 4.0 is a 408.18. Quote Link to comment Share on other sites More sharing options...
DaleMX Posted June 26, 2006 Author Share Posted June 26, 2006 Let me ask this in another way, would you guys do the -7cc with my existing cam and keep the quench at .043 or go with the bigger cam and go with the -2cc to get the quench down to .030?
