Gee I hope this has not been hashed out on this forum already.....
I did do a quick search, but no specific info.
I am considering building a new motor for my 05 GT. (more HP)
Installing the typical P&P heads, cams, springs, headers, etc.
It is the block and bottom end I'm having difficulty with.
FYI, I'll be staying normally aspirated. No S/C or turbos for me.
From what I've read, stroking the 4.6 is not a good idea. I like torque, but do not want to lose top end HP or revs. So if I just bore out the aluminum block, how large can I go and what will the final displacement be using stock size rods?
Using balanced internals and strong valve springs, what will the red line be?
Can I go with larger bore size with a cast iron block? If so, how much more?
Any help appreciated. Partial answers accepted, but not with full credit.
