" From: farna@xxxxxxx " " The overall length of a 199-4.0 might be a problem. It's got a 3.32" " bore (compared to 3.75" on the 199-4.0), so length will be close. The " 195.6 had a 3.125" bore w/short water pump in the 58-63 American, and " a 199-4.0L won't fit those cars without major firewall surgery. There's " still 3" to make up in bore alone between the 226 and a 199-4.0, so I " doubt the longer engine would fit the short looking Jeep hood. yeah, but the 226 is heavy old-tech casting and probably has generous bore spacing. remember, when the sbc came out in '55 with a 3.75" bore, the engineers were sure they'd gotten everything possible out of the block. and it was light compared to previous engines. i still think an ohv connie 245 would be the cool engine swap. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
