Lots of room in the trunk on one of these for a big LPG tank!  4 barrel 327

runs about 9.7:1 in compression the Jeep engine you have is two barrel

and drops down around 9:1, maybe 8,7:1.  I think the two barrel just uses

a shorter piston height.  I've never found the piston heights to know

for sure.

---------> According to the "American Motors Performance Engine Book" 

edited by Dick Datson of Total Performance Independents,  

"It should be assumed that pistons for 327 V8's (8.7 and 9.7 to 1)can be 

interchanged in complete sets as the only apparent difference is 3/64" 

less height on 8.7 to 1 pistons".  The chart shown lists the height of 4 

barrel pistons at 1-15/16, and the height of 2 barrel pistons at 1-57/64.  It 

should be noted that this is actually 2/64 or 1/32 difference in height, 

not 3/64 as stated above.

   I only just got the book and was looking through it when I saw your

note.  I have no idea at this point in time whether or not this book is 

worth the paper it's printed on.  Take it with a grain of salt.
