Indy 415 Small Block

If you assemble it yourself and is first time, then plan on a bunch of $$ for special tools to do good assembly. Ring grinder, ring compressor, torque wrenches, rod bolt guage, cam bearing install tool, cam degree wheel, etc.. If you do it once, then you're set for next time. The engine gurus that do it for business also have all the little tricks to make engine last. All that knowledge & experience costs.
