Well, I put a Musi 502 in my 67 C-10. It made a measley 640rwhp. Lets see a 6.0 or 5.3 do that on 93 octane with no power adder. I would like to see it even with a power adder.LOL. I like my 5.3RC BTW. I just bought an aluminum 5.3 for 350.00 it only had 40,000 miles on it. I kicked around the idea of putting an LS motor in my Pro truck. Nothing makes em shake in the booties like a BB. Especially one that NOW has Twin 88's on it!
