Stonytony Posted January 31, 2014 Report Share Posted January 31, 2014 Well I'm in a bind here. I got a set of jugs 68mm bore with porting for stock stroke. I want to upgrade to a 4mil. If I use the 2mil plate to get the top of the ports right. I would then lower the bottoms of all the ports by 2mm? Looking at this theory alone would that work. I know the plate corrects the tops of ports timing but then piston is goin 2mm lower then the bottoms of the transfer ports. So lowering those by 2mm would be in theory the same as fresh jugs ported 2mm up and 2mm down. Then of course porting for sand/drag. Quote Link to comment Share on other sites More sharing options...
Stonytony Posted January 31, 2014 Author Report Share Posted January 31, 2014 Just thought I would have to lower them by 4mm? Quote Link to comment Share on other sites More sharing options...
Stonytony Posted January 31, 2014 Author Report Share Posted January 31, 2014 Just thought again. Use the blaster piston and it's 2mm smaller from wrist pin to the top of the piston. Then only have to lower the ports by 2mm with the 2mm plate. Quote Link to comment Share on other sites More sharing options...
LCW Posted January 31, 2014 Report Share Posted January 31, 2014 I would just send em to a sponsors and have it done right. You would need 4mil domes also. Quote Link to comment Share on other sites More sharing options...
Stonytony Posted January 31, 2014 Author Report Share Posted January 31, 2014 So could already drag ported jugs be used with a 4 mil if I send them to rdz to have the ports corrected for the stroke? Quote Link to comment Share on other sites More sharing options...
