John in San antonio

[73Chally]

Sure thing. The piston AR is a 7075 block and plug, using a 17-4 stainless piston and cylinder, and a FAL style gas adjuster. Nothing to look at really, it still has excess material for safety during initial testing, just haven't been able to test yet. Turns out most ranges in San Antonio don't want you testing experimental gun parts on their ranges, go figure right.

The challenger is a 73, its packing a little over 600hp from a 393 cu in small block that still looks era correct. Truth is the only stock parts ar e the oil pan and timing cover, everything else is "touched". It's my baby, and I built it. I had some help from the trans shop, but I did it, they just made sure I didn't do it wrong. Quarters, rockers, frame repair, paint, motor, electrical...all me, so when I have issues I know who to blame.

The girdle is going in a 72 340 block I found. I want to turn the challenger up, but I'm not willing to sacrifice the original 318 matching block. Ya, its a 318 car, but some day someone may want it stock. I'm not sure exactly what I'm going to build yet, or if it will be boosted via a centrifugal supercharger or twin turbos, I just know it will be boosted with efi. Yes I know a regular girdle works, I have one in the car now, but Im thinking an aluminum one that ties the mains together and into the pan rails could be better. Besides, I want to learn to cast metal, i have tons of aluminum sitting around, and I want to know if I can do it.
