How do I tell the difference between a 302 and a 351W 2V? I am sure the motor I have is not a cleveland but it might be a 302, who know's? The truck it is in is not the original vehicle that the engine was installed in so I can't check the VIN. The motor is a pre 1980 motor I think. If I identify the casting number where can I take that number to get info on the engine? Thanks.

Look at the block near the base of the distributor. If it is a 302, the gasket under the intake across btwn the heads will be at about the same level as the lowest distributor flange. If it is a 351W, the gasket will be about 3/4" above the base flange of the distributor. And just to cover that base, if the timing chain cover is a flat steel stamping and the T-stat neck bolts to the block it is a Cleveland/Midland block.
