Hey everyone! God it’s been so long since I’ve been on! Last year I bought a Chevy 6.5 for s&g and my buddy bought a 24 valve. Well a year later he wants my 6.5 and I want his Cummins. Beautiful 2001 sclb 2500, my question for y’all is is it impossible to down the road slap a qcsb on it to suit my needs?
