Those heads are capable of running in the 9’s easily with the right matched parts. Looser converter, more gear, and a bigger cam. But making more power won’t help much if you can’t get it off of the line without blowing the tires off. I run ladder bars with my leaf springs with housing floaters. It’s an old school setup but works great. Most of the guys run cal tracs and mono leaf springs. Get a set of drag radials. Loosen the front up. Once you get the traction under control them put 4.11’s in it and about 4800 stall built for your engine. Put a cam in there that can take advantage of the 340’s. A good cam that I used to run that got me into the 9.30’s-9.40’s is the 280/284 @.050 with the .440 high torque lobe. That was with E-heads that flowed 328 and a race weight of 3275lbs. Then you will be making some top end power.
