twisted,
Good point on the overbore. I might want a few more rebuilds out of these engines so a .030 would be better than a .060. Concerning the PW, MPG is not a priority. With the nova, MPG is a priority. the PW could get 1/8 mpg for all i care. The bed is huge (you could fit a late model chevy bed inside it), so I can add aux tanks for better range.
Regarding exhaust sound, I was told by a friend with a 73 nova l6 that he had a dual plane intake. he had a single smithys glasspack and it sounded really nice and mellow. wheather he is misinformed about his intake or not i don't know. does a 250/292 sound "good". (yeah i know everyone's definition of "good" is different) Is it mellow?
