What would it take to make 1.44 lbs-ft per cid ?

Robinson Analytical overcomes an impossibly small budget to build a 435hp pump-gas Olds 307 for the Engine Masters Challenge.

Ooops.....they filled in the ports and only got 1.34 lbs-ft per cid and with only 195 peak cfm.

Its also making 2.23 HP per cfm of airflow with a port cc of 145 cc........Its very EFFICIENT

Like said before it's an impressive engine, it's not an engine most would be able to build.

But yes fits in with the discussion, Say the olds has similar port length as a sbm that's about 260 fps, if look at the chart I made post# 126 that 200 cfm needs about 150 cc to have about 260 fps which is a fairly large cfm to cc ratio.
