Sheesbest Posted December 30, 2008 Author Report Share Posted December 30, 2008 Are you sure you got the solder ALL the way over to the edge of the cylinder and not just in the bowl area? I,m sure that the solder touches the cylinder wall and stays there while turning the motor. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 30, 2008 Report Share Posted December 30, 2008 My next move would be measuring the depth of the cylinders...I honestly think someone decked them. I know this doesn't explain why it was fine with stock rods and stock pistons...but unless we're missing info from you or your info is incorrect (don't take that the wrong way...just saying) the cylinder itself seems suspect.

bansheefreak Posted December 30, 2008 Report Share Posted December 30, 2008 looks close to a 4mil from the pics. if those are 795 pistons.. Quote Link to comment Share on other sites More sharing options...
lunatic Posted December 30, 2008 Report Share Posted December 30, 2008 With that much bore it just might be hitting the outer edge of the dome. Measure the id of the dome maybe all it needs is to have the of the dome opened up? If the solder stays up in the squish area and the piston is only tight on the outer edge that why it never squishes the solder. Quote Link to comment Share on other sites More sharing options...

Sheesbest Posted January 1, 2009 Author Report Share Posted January 1, 2009 I,m going to put the cylinders back with the spacer and machine the head until i get 0.035 squish. And then start lookin for a better setup. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted January 1, 2009 Report Share Posted January 1, 2009 May not happen. If the cylinders are that far below the deck with a spacer...you could put a flat piece across the deck and not get the squish you're looking for...and the port timings could be out of whack as well...
