How can you tell a 305 from a 351?
Hello Everyone!
Simple question for you V6 Pros...
I have a 1970 GMC 5500 Dump Truck/ Grain Truck.
It originally had a 305 in it, but the previous owner let it freeze, and cracked the block.
He told me, that, the engine that is in it now, came from a similar vintage fire truck, (w/ 22,000 miles on it). It runs fantastic, plenty of power, even in a big truck. A friend suggested that it may be a 351 instead.
Are there any identifying characteristics?
Thanks in advance.
-Mike
