They spent much time on research and collecting parts. I wonder what funds their efforts. Just ad revenue? Funny they said sourcing a forged crankshaft is hard since people still give away slant-six engines, after ripping them out to install a small-block. A quick google found the cast-crankshaft didn't begin until mid-1976. They would have been better using an earlier block than make all the mod's to fit the forged crank in the late block. I wonder if they had invested in machining the block before they found that issue. The stoutest blocks are said to be ~1974, with 5 core plugs and a thicker front web. Crankshaft Type/Source/Casting Number? - Slant Six Forum
11 psi boost is probably conservative for the slant, given the higher pressure drops in the intake. What matters is cylinder pressure, but can't know that without special in-cylinder sensors (built into spark plugs for engineering testing). My 1985 M-B 5 cyl turbo-diesel is set for ~10 psi turbo boost. Like the slant, it has intake and exhaust on the same side, so similarly restricted breathing. It has under-piston oil squirters, which seems common in factory turbocharged engines.
Member Bill Dedman of Conway, AR used to argue that boost was an excellent match to overcome the slant's poor breathing. He built a turbocharged slant and drove it a bit, saying just "scary fast". His last post was July 31, 2016. He said he was in his 70's then, so perhaps his racing hobby had to end. When battery-car owners brag of the Tesla Model S Plaid factory 1/4-mile time of 9.3 sec (price $108K), I link this slant-six A-body "grocery-getter" running 9.09 sec (albeit with turbo).
Bill was legend. I still have e mails he would send me in the early 1990s when I was trying to get a 69 Dart 440 to qualify in stock eliminator. He was a wealth of knowledge. RIP Bill
