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.
