He's just putting an LT1 in his S-10, so his main problem will be traction! LOL

Issues you can face with that motor are the Opti, as stated already, the waterpump leaking, and the intake manifold oil leak. My weatherpack connectors at the coil and ignition module also went bad. Aside from that the motor is pretty reliable.

The GM Performance Parts LT4 top-end conversion is not being produced anymore so get yours while supplies last.
