68 barracuda weight

That sounds rear close to what I wanna do with mine. If you dont mind me asking what do ya run with the old 383 and what is the estimated hp? Reason I ask is Im building a 72 demon with a 383 and superstock springs that sounds real close to the set up of you barracuda except the back half part mine has been mini tubbed is all.

The 383 is basically a re-ringed bottom end, milled closed chamber heads, ported. RPM intake, 750 carb. It has stock rockers on a little hydraulic cam that makes about .450" lift at the valve. By best MPH, (108 ) I think it was making 400 HP at 5,000 rpms.
The first trip to the track, with no tuning at all, and a bad ignition that limited me to 5,000 rpm shifts, it ran a 12.4 et. I fixed the ignition for this year, and expect low 12's. I have a solid cam that will MUCH better match my converter. I expect 11's from that. We'll see.
