Re: 1750 rebuild

[Kevin Trent <trentkc@domain.elided>]

Your best bet is to upgrade to a 2L engine.  My understanding is that the 
"early" 1750 engines in the 69 model year differed from the later (71?) 
1750 engines in that they do not have offset piston pins.  This offset in 
the piston pin allows for greater low end torque.  Later 1750 and the 2L 
engines utilized the offset piston pin design.  My personal experience is 
from my'69 GTV with the early model 1750 engine.  When I blew a head gasket 
I upgraded to a 2L engine (carbs and everything else the same) and found a 
MUCH stronger engine, particularly with regard to low end torque.  Later I 
rebuilt that 1750, with a rering and reusing the piston/liners, and put it 
into a Berlina.  The engine and car has always been gutless off the 
line.  I also have 2 other Berlinas, both with 2L engine - and one is a 
beater - and the superior torque of the 2L is easy to feel in those cars 
over the early 1750 powered Berlina.

(striking a match)...the best use for 1750s is as an upgrade to a 1600 (and 
1300?) vehicles because the crankshaft will accept the 1600 (1300?) 
flywheel and then  it is a bolt in.  By the same token, the 2L is the best 
way for easy speed in a 1750 vehicle, because it too is an easy bolt in 
upgrade.  IMHO....YMMV...etc..
