Musi Pump gas 555

Musi sells a crate Chevy 555 touted as big power at 676 -723hp runs on 91 octane.

This seems very doable on a 555 Pontiac with 350 cfm e-heads.

What do you guys think?

The PS may have been salvageable, not sure. There is some rot on the lower trunk drop off.

I will blow out, vacuum and treat inside the trunk area on the drivers side.

No data, but I don't think you'll pick up. The SD KRE heads are very efficient. Many of those heads used in combos on this site that make nearly 600hp.
