No worries. We're just ball parking here anyway.

Compression is 13:1

6.0" rods

Heads are SB2.2 worked by Curtis Boggs @ RFD in Virginia. I am guessing you know of him or have heard of him.
Yup.

Peak is 410-420 cfm at .900 but around 395-400 at .700 closer to where my cam net lift ends up. Low and mid lift numbers are strong. The work done was intended for road race (vs the Nascar CNC programs) and not max hp at high rpm.
Very similar to Busch/Nationwide numbers back then.

Header is stepped 1-3/4 to 1-7/8 to 2.... 3.5 collector. Do not have length. It is a Profab Nascar type take off I believe.
Cool. Also probably a Busch/Nationwide piece.

Do not know cam degree number.

Cam solid roller.

Block is Dart Little M -- not a Bowtie/SB2 block.... so that must make it 4.4" I am guessing.
It probably is.

Thank you! Me too.

My calcs show 818hp @ 7000 rpm & 645# Torque at 5800rpm, but I had to guess at lot of stuff. Now lets go see what it really does.
