I run 12.5/12.6s with mine, i run headers & 3.73s with 27" MT Radials, adversage 60ft. is 1.81, best of a 1.79 so far.




Impressive!

I have a set of 24.5 x 8.5 slicks I'm mounting up as well to give me a bit more gear ratio if required. They were good enough for my 10 second Reliant I don't think my Duster will overtax them!

I'm going to try both sets of slicks at the track along with some carb swapping and other fiddling.

Are you running a 904 or 727? I stuck with the 904 to give me a slight reduction in ET.

Its hard to say with those corked up manifolds.





I thought so too but have been eyeballing this article-

The dyno results state a 8 hp & 20 ft/lbs difference between 318 manifolds and cheap headers with a 300hp crate engine.

Headers would be nice but doesn't fit into my vision of stock looking under the hood.

BTW, your engine is fresh, so did you use FTs or factory style dished, i'm running on a junkyard short block & RHS heads.



Factory slugs.
