We all have heard plenty about head mods with porting and polishing and shaping valves. I know about cam shafts, valve springs, pistons and rods. Is there anything that can be done with the block itself? Or is it just a hunk of metal to hold it all together?

Thanks

 

You can do tons of stuff to the block like boring it out, sleeving it, installing new pistons, rods, stroker kits, etc.

 

depends on if you want to build for boost or NA

 

I just got done with my block build for n/a. i got about an average of 25 whp and 25 ftlbs of tourqe through the power band.
