which is the better motor, the Ford Performance 5.0L 4V Aluminum Engine Block - Performance Race Block, or the Ford performance boss modular 5.0L engine block? and why? what makes the one engine better than the other? Thanks for your help

Welcome to the forums. sorry to be so little help but I'd ask this in a different section since this is the 4cyl section. If I had to take a guess each one would be different based on application. aluminum vs iron, 4v vs 2v vs 3v. the blocks may be similar but heads may have different specs
