Nailhead

[Grhopperass]

I'm cirrently running a 401 nailhead in my model A.
Its a tight fit.
I would like to go with a 425.
Are the outside diamensions of each engine the same
and will my exhaust headers and intake fit.
Thanks

The dimensions are the same and your stuff will fit!

Yes, everything is the same. Now all you'll need is one of my "Mini" "NailHead" starters to make the swap even easier.

Hello Tom:

My 401 nailhead has one of your starters.
Its coupled to a st400 Trans.

425,
Thanks

If the 425 will be mated to the TH400 trans. NO PROBLEM, it's a bolt-in.
