opinion on R3/W8 340 (358ci)

That's my concern, headers and dry sump location, dry sump is located just below 1&3 cylinder banks, does anyone make 2"+ headers for w8 r3 blocks that fit a Scamp..
The scamp is a 73 with a full fiberglass 71 Dart nose, hood, fenders and bumper, has 8 pt cage, no rear seat, front racing buckets, tubbed with 29.5 x10.5 slicks, 5.13 8.75 rear with spool, 727 with dynamic 9" converter 4500 + stahl, goal is to be low 10 seconds

You'll be making everything. The craftsman stuff didn't have a large port, probably don't need a 2" header here, you can buy flanges and adapt a Hooker 1 7/8" header but you will be modifying them due to the dry sump (I'm guessing it's a 5 stage pump and as a bonus one stage is probably a vacuum pump) nothing about installing one of these is simple.
I know of a 3.30 stroke 4.185 bore truck motor that was raced with a glide and a 4500 stall moving 2850lbs and it was an easy 5.70 car to the 1/8 with a 9:1 CR. These motors just plain RUN! That was shifted at 8000
