360 magnumblock?

magnums come on fuel injection vehicles...so they all use electric fuel pumps..
so chrysler does not put a eccentric for the fuel pump on the front of the camshaft...therefor the timing chain cover is different..

like said...just run an electric pump....if you want to run a mechanical fuel pump...hugheengines.com sell an extension..about 20 bucks i believe..but then you need the LA timing cover...which can be had from any 318-360 engine...cheap from junk yard...

the only advantage the magnum block has is the hydraulic roller lifters are cheaper.....

if you use the magnum block...you will need to use magnum heads also...

and what are nascar lifters?????
