The "Poor Mans Rajo" is an old term used to describe a Chevrolet Head cobbled onto the Model T engine.

This kit is attached to a Model T block using an adapter plate manufactured by Neal Jern out in Redding California.  He calls it the "Jern Thunderbolt" kit, his name is cast into the aluminum rocker arm cover.

I am offering engines built up like this in limited quantity. 

If you would like to own one, please give me a call. 

The head in the photos is a 1928 Chevy, chosen for it's 1.5:1 rocker arm ratio.  This ratio gives the stock T cam .375" lift at the valve.  A new 280 cam will net you .420" lift.  With the right combination of parts you can get up into the 100 HP range to push your T down the road.  The "6" written on the side of the adapter plate refers to the compression ratio.

If you want one of these engines built, please give us a call or send an email.  This head setup will add aprox. $2,000 to the cost of a complete engine rebuild.  Please understand that we will not put this setup on your old worn out engine.  If you want to purchase just the kit, please contact Neal Jern in California.  He manufactures this kit for both the Model T and Model A Ford.  He advertises in Secrets of Speed Magazine.
