To say you have an E85 motor in an older car, is sort of cool, but do not
do it thinking your going to save money on gas,,,,, octane is horse power,,,,,
it take so much HP to move so many pounds at any given rate, and thus when
octane is lower it will take more gallons to do the same job,,,,,at least
this is what my engine builder told me,,,check with someone that has a flex
fuel car, and see if they do not get more mpg and performance with regular
gas than e85

Yah, the
piston people asked me that question and I wasn't sure what to say. My
son wants me to build an E85-only motor and suggested a CR of 13.5 - 1 ... but
I don't think I want to do that. Others have suggested 10 - 1. The
piston folks say they can build me whatever CR I want. So perhaps this
needs to be changed to a question about CR ... so I could use some help here
as I have no idea how to figure that out.
I have a 3:55 gear in the
backend, my tire size will be different than what they are now ( haven't
decided for sure yet ), and I don't know the exact weight of the
car.
Jeez ... this is harder than when I picked out the cam for my poly
... just used what Gary P said to use :-)
Thanks,
Brian

I would suggest holding off on the cam selection until you find out
what your going to end up with for CR (pistons),,,, your gearing, tire size,
and total weight are also considerations that need to go into cam
selection.
413 pistons are not everywhere, and usually more expensive
than 383-400-440, I believe that some have found it cheaper to have block
sonic checked and bored to 440 specs.

I'm
rebuilding a 413 and am looking for some help selecting a
cam.
Muscle Motors did their race-prep service on the block, bored
it .030 over.
The 452 heads have been prepped by a local machine
shop - milled the heads, new valve guides, hardened seats.
Looking
for a mild street cam as this is a daily driver during the nice weather
months with an occasional trip down the track.
I also need to find
some pistons ( or have some built ) - help with that process would also be
appreciated.
Thanks in advance,
