I built my 528" Hemi with a Mega block all from scratch with my good guy WD pricing & pilfered & bought what I could from Craiglist, Racing Junk & Moparts Etc. I am lucky enough to have less in mine than what a crate Hemi costs even with all of the Nitrous foggers plumbed with more than double the power just on motor & much less than what the conversion costs.
