How do you tell 350 4 bolt main from 2 bolt main Lt1?
To differentiate between a 350 4-bolt main and a 2-bolt main LT1 engine, examine the engine block's main cap configuration. The 350 4-bolt main engine will have four bolts securing each main cap, while the 2-bolt main LT1 will have only two bolts per cap. Additionally, the LT1 block will typically feature a unique casting number and may include provisions for fuel injection, distinguishing it from the older 350 engine. Lastly, the LT1 will have different accessory mounting points and a distinct intake manifold design.
