IN STOCK & READY TO SHIP

Designed for the modern Hot-Rodder looking for a complete, turnkey drop-in LS engine package! This engine comes with a low-profile hot rod swap oil pan, that fits all classic chassis. The EFI System is the Edelbrock Pro-Flo 4 kit, which includes a sequential port injection manifold. This greatly boosts the efficiency and drivability of the engine compared to traditional throttle body injected systems. It is also very easy to wire into your vehicle. The harness is labeled very nicely, and in our opinion is the easiest in the industry to install. The Pro-Flo 4 system will be fully calibrated on our engine dyno, so you don’t have to worry about finding a tuner to work on it. The serpentine kit that we include is Holley’s Mid-Mount Serpentine Kit. It utilizes a modern LT1 style water pump, 1 wire alternator, SD7 A/C Compressor and Type II Power Steering. This LS3 Hot Rod is built 100% with brand new parts, and is fully dyno tested, tuned & broken-in before leaving our facility. It features our Smeding Performance fully forged rotating assembly and is topped off with Smeding Performance 11° LS3 cylinder heads. Even though this engine makes over 500hp, it is a fantastic daily driver, and is very smooth & efficient. Like every Smeding Performance engine, it is backed by our industry leading 3yr / unlimited mile warranty.
