Not sure but looks like a 302. Can't exactly tell where the intake ends and the block begins. Then again that looks like a 351 header on the passenger side. Seems like mine has less clearance between the heads and the edge of the compartment

 

Not only do they fit, they fit really well. Miles of space, no interference with the dog house or the floor heat shield.

 

Well damn those are pretty.

 

That's nice. You even got the damnable AIR looking right.

To ID a 5.8 over a 5.0 stick your hand down at the base of the distributor (if you can't see) & feel for this angled casting.

No angle, it's a 5.0

 

He's got a 5.8. The passenger side header for one won't fit a 5.0 The collector would dump right into the starter.

 

Those look and fit nice. Nice clearances.

I hope my Hedman long tubes fit that nice on my 5.8L.

 

Looks fantastic.

I had Dynomax headers on my '78 with 351w and loved them. They fit pretty well as well.
