Help with Small block 305!!

Here's the story i bought what was supposed to be a sbc 350, but when i looked up the block numbers it turned out to be a sbc 305. I was told i can convert my 305 small block into a 350 by changing the cylinder heads. is this true?  

no that does not change the bore or stroke of the motor.  

you got ripped off bad dude i would take a head off that 305 and rap it off the guys head who sold it to you.  

Rather than jump to conclusions and assume whomever sold the engine to you was intentionally trying to mislead you give him/her the benefit of the doubt and believe that they were just as uninformed as yourself. Mistaking a 305 for a 350 is a common mistake.  

Ya mistaking a chevy 305 for a 350 is a very common thing in my area I have had a lot of costumers that have brought engines to me and was told it's a 350 and it was really a 305.

see if the seller will refund your money, if not you can make a cool table out of it and get a 350.  

The same thing happened to a friend of mine. They told him it was a 350 so he bought it. Took it home put it on the engine stand and grabbed the snout of the crank. The crank had about a 1/4 inch of play front to back, and it was a 283.
Use that 305 as a boat anchor. Thats about all its good for performance wise. It would cost you about the same to build a 350 with more hp/tq. Also check the casting numbers before you buy!!  

I agree always check the casting numbers.

yeah you dont want that 305  

Just sell that 305, I know some of the guys at customclassictrucks.com and classictrucks.com would be interested in the 305.  

Ya 305's are capable of making power but just cost more some one will want it.
