R&S Machine is the leader in engine block technology for junior dragster racing engines. Leaving no need for unnecessary grinding on cam shafts or connecting rods. R&S has relocated the cam and the crankshaft giving the necessary clearances needed to eliminate engine failure. All blocks and complete engines come with the R&S Dual Cam Bearing System. The new Terminator block is available from 3 - 3.75".

R&S Machine also makes a direct replacement for the Blockzilla, which will accept the side cover and cylinder head of a Blockzilla block. This block also comes with our R&S Dual Cam Bearing System.

All blocks come with dual cam bearings!
