" From: Matt Haas <mhaas@xxxxxxx> " " I was browsing through eBay last night and saw that there was a set of " +.040 199 pistons and rods for sale. The seller didn't list years so I " pointed out that 1967 and earlier are different and as it turns out, these " are the early ones. The 1967 and earlier 199 and 232 pistons run about " twice as much as 1968 and later so if someone is planning on rebuilding an " early 199 in the near future, this may end up being a good deal on them.The " item number is 4609708381. you don't -have- to use '64-7 slugs if you can stand a little more compression. crude calcs -- '68-'70 199 flattops would yield 9.7:1 with a '64-7 head. '77-'9 232 slugs [inferring a 6cc dish from other facts - anyone know?] would yeild 9.2:1 in a '64-7 199. you may well have to adjust timing or even recurve the distributor, but recurving kits for the delco are plentiful and cheap. it'd probably still run on 'regular'. also from other evidence, i infer that '68-'76 232/258 slugs have a 12cc dish, more than offsetting the 10cc-smaller chambers of the early 199 vs. the late. they'd give 8.3:1 compression. this all is based on some guessowrk so my calcs could well be off. " Also, if +.040 pistons are too big for what you have in mind, Kanter " (http://www.kanter.com) has them starting in either +.010 or +.020. that's always good to know. egge machine co is another good source for old/obscure engines like ours. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
