Hello guys,
i tested my car the first time on a dyno last weekend. I built up this engine last winter. The engine should be a good streetable combo for my 67 fastback.
Here the data:
- 331
- scat cast crank
- scat forged i beam
- probe srs piston
- 89 roller block
- afr185 with 61cc
- comp ratio 10.7:1
- ed curtis upgrade valve springs
- ed curtis custom cam (build for torque in low to mid range)
valve lift ex. .5632 int. .5728, duration ex. 228 int. 224 @.050, lobe 112*
- comp pro magnum roller rockers
- trickflow main girdle
- 75mm pro-m mass air
- 65mm ford racing tb

- custom cold air induction
- 24lb injectors with 50 psi (27.5 lb)
- hooker long tubes, no catalyst

I make all my eec changes with the tweecer rt. Total timing was stock 26*,
air fuel ratio @idle 14.7, @wot 12.8
Measured values:
370 PS flywheel (near your HP) @ 4700 rpm
420 lb-ft @ 4500
average power 233 PS
average torque 321 lb-ft
power loss @ 4700 rpm = 30 PS (manual transmission, tremec tko)
what do you think about that numbers
