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
