Quote: i looked at my ld340 and there isn't much room there also, it looks like if you open it to the good gasket or plastic spacer there would only be about .030 on the secondary side unless you weld. NE1 have a pic of a LD340 opened up to T-quad size.
I don't have a picture, but I hogged my LD340 out a few years back and there is plenty of room left after doing it and I'm using the big bore TQ with no issues at all.
