i found this guy thats selling a 1977-1987 351W long block for $650. its brand new and has zero miles.
a) will this fit into a 67 coupe?
b) are all 351W long blocks? or short blocks?....ive heard people calling them long blocks and books refering to them as short blocks. are long blocks 351 for trucks and short block 351 for car applications?

short block and long block refer to if the engine has heads and other accessories, short blocks is blocks and rotating assembly. Thus u can have a short block v12 and a long block honda vtec

 

I would buy it,, especially if you were planning on getting a new one anyway.. ITs costing me $1086 to rebuild my engine back to stock,, so think about it..

 

Yeah, Paddy is right. Maybe you are referring to small block and big block engines. Yes, it will fit just fine. That's a very good price, so grab it.
