i'm new here so i'm not sure what i'm doing but i would like to know if a 1970 351 will fit in a 1968.

 

Yes it will, they used to run 428s in those things......

What engine is in the 68 now? If it's a 289 or 302, the 351 will go in using the same mounts and transmission. But you will need different headers if you're using those, and all of the accessory drive stuff from the 351. Hood clearance can be a problem, depending on what intake you run (stock 351 should be fine).

We may need to ask if it is a Windsor or a Cleveland? Both will fit but you should be aware of what you have.

If it is a W; You may need an earlier water pump or the bottom rad neck will not be on the same side OR change the rad which may be better idea to improve cooling. BTW I do have an old set of 351W headers from my '67. Rusty but free if you want them.

 

whats the diff between the windsor and the clevland?
