How much HP from SBM ProComps? Well... 670HP!

That's probably an HONEST 620 HP you have.



Like I said I honestly don't know. My combo runs better in the 1\8 mile (6.001)
Probably because of the solid lift can but I just like to show guys what can be done on a budget and a big block isn't always needed. Including the R3 block I have around 7500.00 in this engine.
