422 dyno fail

The shop called today to tell me they made a pull with a 750 Edelbrock carb and it made 355 hp and 421 ft lbs. I think it should be at least 100 more on each spec.

Looks like you ended up right at about 100hp more, along with 85ft/lbs.

Notice how much better the bsfc #’s are(than the last sheet previously posted).

Same headers as the last test?
Same carb?
Any carb spacers tested?
