Mark IV big block VS 6.0 or 5.3?

[Lsx10]

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!

a 502 is not a 396, and the 364 6.0 will easily out perform the 396. the extra 32 cubes is quite a bit, but the gen 3 motors are more efficient. it will take less to get the 6.0 to 400+rwhp then the 396.

I know the 396 can be punched out, given a roller cam blah blah blah. but a 396 vs. 6.0 the 6.0 is a better engine any day. as far as the bb being intimidating, i've seen alot of loud intimidating cars get killed by 5.0 stangs and ls1/lt1 f-bodies. then they just seemed loud.


To the OP
do what you will be proud of owning when its done. the bb is old school and is a beast, the 6.0 is updated and is a beast, the 5.3 is a cruiser that will get you good milage to shows/cruise nights, the ls1 is updated and more costly then any of the other options.
