Looking for opinions on Mopar M1 single plane intake

I think I'll make it out that way Friday. Car ran decent at Walla Walla.
Best pass at WW before was 6.83 @ 98.
New best of 3 hits 6.74 @ 99.8 still sorting out AFR on the wide band.
Still have an 850 annular carb to try. Hoping it will improve the short times a bit over the 750.


Never been to WW. Is it 1/8 mile only?
