302 vs 5.0 HO
Hows everyone doing just had a question. Are the two cranks for these engines the same profile? I know the cams are different but can you just switch the cams, lifters, and push rods and interchange them? Or am i missing somthing?

Not if the HO is a rollor cam...the true 302 28oz balance and a lot of the early 5.0 did not have the provisions for the rollor cam.

sorry i took the ? the wrong way...... but you can't just swap the cam and lifters from a roller motor to a non-roller motor, which is how i took the ? Sure you can run rollors in a non-roller block but you need aftermarket lifters with H links.
"I know the cams are different but can you just switch the cams, lifters, and push rods and interchange them?" No you can't.........
The cranks are different too the 5.0 is 50oz balance and the 302 is 28oz also the ends off the two cranks are different where the rear main seal is.
so what do you mean by profile...they are completely different castings....Trust me I know, I have had both of them side by side and they are different, but you can interchange them you just need to remove a ridge off the 5.0 crank to run it in a 302 block and you have to use the flywheel and balancer that came with the crank......can't use a 28oz flywheel on a 50oz crank
My 2 cents take it or leave it........

Because the 302 blocks do have the taller bores needed for the taller stock roller lifter and it does not have the bosses for the craddle ??? that holds the lifters straight on the cam..that is why you would need the aftermarket lifters with the h-links, or you could drill and tap the block and run a small base circle cam which lowers the lifters into the shorter bores.
yes the cranks are the same if you look at the rod journals........
some others can explain it better.......

What year engines are we talking about.
The early ho engines had flat tappet cams(non roller).
If you are just switching cams ther shouldn't be a problem long as you are using same type of cam the engine block is set up for( Flat tappet or roller).
Starting in 1983 they went to 50oz flexplate/flywheel.
My answer was yes to running an ho cam in a regular 302.
as for as profile i'm not sure about.
