Race 1 - GM Factory & DIRT Car Sealed 602 Sprint Car Crate Engine with 604 style Oil Pan !Click on "Documents Tab" above for The DIRTcar Pro Sprint Car Division FAQ Sheet!
These all new 602 sealed sprint car engines offer affordable, dependable and competitive solutions for Sprint Car Racing.
Cam is drilled and removable spud is installed without the engine being disassembled or any GM factory sealing bolts removed.
For chassis requiring oil pan clearance, we install a 8QT "late model style" oil pan. This oil pan provides the clearance needed for normal/original engine mounts.
This engine retains all the GM factory security sealing bolts (EXCEPT the OIL PAN) and additional serial numbered cable-style security seals. Cable seals are also wrapped with tamper-proof tape which is printed with a QR code. This QR code can be scanned with any smart phone and will take you to a web page that shows engine build date, serial number, security seal numbers and location of security seals. The engine build sheet will also be updated with any future work or maintenance done to the engine. DIRTcar security cable seals installed & documented.
Also included with this engine is the patent pending Crate Innovations crankshaft hub & slip yoke package. This assembly bolts directly to the crankshaft and does not require any torque tube housing modifications. Throttle Plate and Linkage Package.
