TeRC_FK Posted November 4, 2011 Report Share Posted November 4, 2011 I'm rebuilding my top end but I've got no idea what size my domes are and even if they're right. Right now the left cylinder/piston is good but the right is trashed. The left(good) cylinder's dome is severely pitted but the cylinder and piston are fine. The right dome is fine while the cylinder and piston are trashed. Any idea what causes this? Once I rebuild the top end I need to know what size domes to replace them with and what should the compression be. I've got an '02 with a mild port, pro design cool head, 34mm PWK carbs, V-Force reeds, and Toomey T6 exhaust. I'm near Glamis at about -100ft elevation.

Chevy4life32 Posted November 4, 2011 Report Share Posted November 4, 2011 The dome size will be decided by what octane fuel you are planning on running. If you let us know that, then we can help you decide what domes, and the one cylinder being messed up is probably cause of bad jetting on one side or even a possible air leak. Causing one cylinder to run really lean or way to rich. Hope this helps. Quote Link to comment Share on other sites More sharing options...
TeRC_FK Posted November 4, 2011 Author Report Share Posted November 4, 2011 I've been told to run half 110 and half 91. I'd like to use that as its more economical than 100% race fuel. Is this ok and what size domes then? Once I'm done I'll triple check jetting. Quote Link to comment Share on other sites More sharing options...
EvilBanshee Posted November 4, 2011 Report Share Posted November 4, 2011 A buddy of mine has a 350 ported shee with 19cc domes. All he runs is 91 and a few " GLUGS" of octaine booster. He seems to be getting alone fine. Im not sure where he is at for timing though. Quote Link to comment Share on other sites More sharing options...
TeRC_FK Posted November 4, 2011 Author Report Share Posted November 4, 2011 I thought it was bad to run octane booster. I have an idea but what exactly are cut domes? Quote Link to comment Share on other sites More sharing options...
TeRC_FK Posted November 5, 2011 Author Report Share Posted November 5, 2011 Can you order custom cut domes just by telling someone your setup? Quote Link to comment Share on other sites More sharing options...
