joey b Posted December 30, 2003 Report Share Posted December 30, 2003 What combination of heads/block mate up to give the highest compression ratio. Can it be done without any interference (aside from timing belt)? Quote Link to comment Share on other sites More sharing options...
dykz34 Posted December 30, 2003 Report Share Posted December 30, 2003 The 96-97 DOHC had the highest compression stock. Quote Link to comment Share on other sites More sharing options...
joey b Posted December 30, 2003 Author Report Share Posted December 30, 2003 I was told to put I believe 91-95 heads on the 96/97 block to give a CR up over 10 I think. Quote Link to comment Share on other sites More sharing options...
dykz34 Posted December 31, 2003 Report Share Posted December 31, 2003 That information would be false. The CC on the 96-97 heads is a bit smaller. Quote Link to comment Share on other sites More sharing options...
joey b Posted January 3, 2004 Author Report Share Posted January 3, 2004 are the pistons different? At the top of the stroke are they flush with the top of the block? Quote Link to comment Share on other sites More sharing options...
dykz34 Posted January 3, 2004 Report Share Posted January 3, 2004 The 96+ pistons have more of a dome. I believe they stick out of the block at top of the stroke. Quote Link to comment Share on other sites More sharing options...
