We use these DART blocks in our blower, turbo, nitrous and high RPM combinations. We've run over 1500hp through them and have yet to have a failure with any of the SBF DART blocks we have used. The blocks ahve several features that make them a better bargain the the FMS race blocks including:
- Better Machine work (DART Blocks generally require less machine work than comparable brands to finish for assembly)
- DART blocks have billet main caps (Ford blocks are ductile iron)
- Revised Oiling, DART blocks have priority main oiling modifications for increased oiling
- 4.185" overbore capacitity, DART's thicker cylinder walls allow for increased cylinder stability (better ring seal = more power) and greater overbore capacity.
