There is a lower first gear, gearset avalable for 727 use. However
it is not cheap. But then again, neither is an aftermarket OD unit.
In the '60s the lower first gear was used for the heavy cars for good
off line response in drag racing.. As such a sturdy trans is required
as noted by D2, the spacing is radical and slamming a high powered
motor into a higher gear at high RPM was a strain on them.. However,
for our use in Imperials I think the use of the lower gearset would
be a great addition.. I realise not many would wish to make that type
of outlay in funds tho..
D2, being as you have a '68 Imperial,which means an 8 3/4 rear axle
ass'y, there is no 3.73 gear aval.. 3.23 3.55 3.91 4.10 etc..
I would be curious as to what you call a "big" cam.. If you have cam
specs aval I would be interested in seeing them.. If you have part
number and manufactor I can look it up myself.. :)
Thanks,,
