A guy i work with is wanting to do this swap, and im just needing any advice... everything i have found is for a 351W, but noting on the cleveland
thanks in advance!!!
I am in the middle of doing this swap into my 86 but I am cheap so I am using a 351M truck pan that I modified and some 71-73 Mustang headers that needed a couple of tubes reworked.Other than that it is fairly straightforward.Uses the same mounts as a 302 but you might need a small spacer under them to run some of the aftermarket pans and the bellhousing pattern is the same as a 302-351w.351c uses a 28 oz balance so you need either a 351w flexplate/flywheel or one from a 302 built before 1981.I haven't checked for hood clearance yet but I have heard that in most cases you will nedd to run a scoop or an aftermarket hood.
