Desk Top Dyno

Using the Wallace dynamic compression calculator…….
With 14:1 and the cam in at 106, and 0 ft elevation, it shows the cranking pressure as 216.

As for a simple SB 700+hp combo…….from about 20 years ago…….(SBC unfortunately)

Stock block 406 with an early NASCAR 18* top end off of a 9:1 358 Busch North engine.
Those engines would make a tad over 500hp with a 390cfm carb(pulling close to 8” of vacuum at 8000rpm).
Install intake, heads, rockers, etc onto a 12.5:1 406, add a 4150/4500 carb adapter, 1050 4500 carb, and increase the cam duration by about 20*…….and wa-la …….725hp.
That particular set of heads flowed in the 330’s.
