Bonneville America Forums Forums Technical Forums Performance Mods Big Bore,liners or no?What best/

just to add another opinion i have the regular weisco kit with steel liners. i went this route because there are A LOT of poeple with it who have had no problems at all. it has shown to be a solid mod. you can install it yourself for about 1000 bucks so cost is not a big deal, plus in regards to rebuilds if you do it yourself, then you realize its not a bad job and changing the liners and rings every 50-60k its not that expensive and can be done in a weekend. but the D&D guys seem to be happy with there kits so i cant say anything bad as i have no expierence with them. but you should know there has been talk of how thin the stock liners are when they are bored out, i have heard they get very thin which can cause more expansion with heat which effects power/seal of rings. but again they guys with the kits report they are happy so its really your decision. just do as much research as you can and decide which rout you want to go. tons of info about this stuff on here, the rat site, and the delphi forums. goodluck
