Superdog Posted November 15, 2011 Share Posted November 15, 2011 Are there any differences between a 2v block and a 4v?The Superliner I just drug home has a ventilated block,I've got a good 2v 350 block.,just wondered if they were compatible of if there was some little differences that would prevent me from building a good engine from the 2.

theakerstwo Posted November 15, 2011 Share Posted November 15, 2011 The difference in the two blocks is the cam size. 4V uses a larger cam bore.

Dylan Posted February 3, 2023 Share Posted February 3, 2023 Can you put 4v heads on a 2v block? Quote Link to comment https://www.bigmacktrucks.com/topic/21616-e6-350-2v-vs-4v/#findComment-524469 Share on other sites More sharing options...

If It did work you'd be putting a lot of stress on a cam not meant be pushing twice the valves with a different variation and possibly timing. You probably could bore out the 2v block to accept the 4v cam but It would be better to just keep the 2v heads.
