Good friend of mine had a very similar combo in a tube chassis Daytona. 499" RB, stock unported 346 heads, solid FT cam, M1 4500 and a 1050 and a 727 trans. Ran 6.50s in the 1/8.

Later on he bought some Indy SR heads for it. First pass off the trailer it went 6.teens w/ very low timing and no tuning. Should have been 5.9x capable but he sold it before ever running it again.
