Well the cam/convertor/and torker becomes more understandable with that difference.Not all good news though,now the compression is a little low for the cam IMO.
Might help a little to install the cam 4 degrees advanced to help that some.
And that cam will need the adjustable valvetrain,so that explains the poly-locks.
I'd want to find out exactly what pistons are in there,and exactly what the head chambers cc at to come up with a better idea what the CR is now.
I'd probably still prefer to use the performer also.
Also do you have any idea what gears it has?
