Today I shipped Falcon Machine the case, heads, new ARP case bolts and 7x replacement cylinder studs. For the 3100 a.k.a. "Big Boy" modification. Thats replacing the stock piston and cylider jugs with 94mm VW pistons and jugs - the largest that will physically fit between the cylinder studs. This modification requires boring out the case and heads for the VW parts and then trimming the VW jugs to fit the Corvair case
