That is why they build and tune their engines for peak HP rather than the big, flat torque curve that makes street driving fun. ... This engine needs to be tuned for the street. Perhaps it will work with the 850 carb. A professional can show you what is possible.

Went from 92 holley jets on the Primary side to Max jet 96s (which are the equivalent of Holley 86s), knocked the squirter on the primary down to 31 from 37 (which was on the cusp of needing a 50cc pump to support-from what ive read with 37s), and threw a bottle of Lucas octane boost in a new tank of fuel.
What should stand out here is idiot me made these changes concurrently...
Result? WWAAAYYY better manners, hesitations stumbles and all are pretty much 99% gone, pig rich gas smell is better. Still dangerous pinning it on the freeway...

The stock jets on an 850 are 84s so the 86s are still fatter than stock.
