6.1 Hemi.....= 370 cubes....What is the bore and stroke.....What is the main diameter and rod diameter....what is the rod length.....

4.055 3.580 370 8 6.200 12.6-1

Pretty straight forward looking engine specs.....not unlike a small block chev...with lots of compression.......Not your average street cars compression ratio!

Piston appears to be a Semi Hemi design...not a true Hemi.....

What is the cam lift......

385 370 .0135AB Dome .137 14.8cc 2100/1600 584/552 Beehive .039

Killer valve sizes and cam lifts.....easy to see why it runs as fast as it does....

What do the heads look like.....what is the intake and exahust port CC's and what do the heads flow.....port shapes? All this stuff says a lot about the usable rpm range of the engine.

If the heads are even reasonably decent.....it makes a lot of power.....and obviously they are from the numbers run by others.....

Doug Duell and Irv Johns have run some 9.80's at what weight?

370 cubes is pretty small to be running 9.80's at 132-133? I am guessing they are spinning them pretty hard to run those kinds of numbers....so my educated guesswork says lots of RPM might be normal for one of these.....
