434 SBF dyno #'s

Post by 86 t-bird »

Well I finally got the engine together and made it to the dyno. The best we got was 807 hp @ 8000 rpms and 597 ft lbs @ 6700 rpms with VP C-16. Im sure it would have made more power with C-14, (already had the C-16) because the BSFC #'s were .54 at peak hp on the best pull. Oil was Brad Penn 30 wt. break in oil. Oil I will be racing with will be Brad Penn 10w-30. The engine made its best power with 32 degrees of timing, 88 jets(squared), and 3 1/2 inches of carb spacers. It picked up everytime I added a spacer. If I had more spacers I would have tried them. I guess it needs more intake??? The headers I have are 2 1/8 stepped to 2 1/4 and are big for just motor, but I think they will work when I put the juice to it. Overall I am pleased and I think the engine will fit my needs well. :D :D :D
