[FC] '61 Rampside conversion EXPLAINED (dont do it)

[James Davis]

Heartily agree.  When using a 64 and later crankshaft (2 and 15/16" 
stroke) you should always use an harmonic balancer.  The rear engine 
mount for the 61-63 cars with air conditioning and all 64 cars has room 
to accommodate this balancer (and room for the additional sheave to 
drive the air conditioner.  61-63 FC's do NOT have sufficient length in 
the engine bay to accomidate the extra length of this style engine 
mount.  It is necessary to section 1.15" out of the rear structure of 
the FC in the engine bay to make sufficient room to make it all fit.  As 
for front engine mounts,  the 61-63 4-sp are quite different from the 
64-65 4-sp mounts both in its shape and how it mounts to the 
transmission (P/G are the same for all years).  See the Clarks used 
parts catalog or the P&A 30C for the differences.
