This is the flowbench data from the ported cylinder head:
lifts stock head flow (cfm) ported head flow (cfm)
0.05 47.6 36.1
0.1 85.2 68.6
0.15 96.6 110.1
0.2 114.4 163
0.25 131.7 210.9
0.3 141 233.3
0.35 167.3 249.3
0.4 202.6 261.2
0.45 205.1 265.6
0.5 207.7 267.7
0.55 207.6 268

The motor does not have AIC. It was plugged. The Electromotive TEC2 will be used to tune the motor. To have it idle the adjusting screw on the throttle body is set so the throttle bodies are a bit open. This is a common practice on racing engines.

thank you.

basically i cut the runners right at the flange and had them rewelded. the runners at that point are round so the work to match the pipes was easy.

the PITA job was actually matching the itb's to the head. there was a lot of grinding and filling of material to make it work.

i think i spend just as much time getting the ITB's to match to the head as i did on all the other head work. lol.

replace the word "kids" with "thousand dollars" and you have a deal.

i will do best offer on this. worse come to worse i guess i will part it out. i really dont want to because the tomei solid lifters are already shimmed and doing it again is a PITA.
