Great information! The calculator seems like a very useful tool if I understood all of the figures. I will go with the suggested Speed Pro/TRW pistons once the block is bored and I know the size needed. I am really wanting to get to an optimal balance for performance, reliability, and efficiency with this build. With the transmission being manual, would I benefit more from a higher lift cam like the 2802, XE268, or XE274 rather than the 2801? I have also been considering the roller cam option for longevity and performance. What are your thoughts on this and suggestions for specific cams if possible? The pricing difference seems to be relatively slight by the time you compare cam, lifters, springs, hardware, timing set, etc so I would like to hear thoughts on this if the "upgrade" is worth it. Valve spring suggestions would be appreciated for the flat tappet options mentioned as well. As I mentioned before, I will be running the Fitech EFI kit with the Edelbrock Performer intake. Thanks again for all of the support and insight.
