Was that one of those older higher compression ratio motors.
With 8.3 compression a good cam and headers.
6,000 safe RPM for an occasional or a frequent shift RPM
I'm pretty low budget so I bought a couple sets of headers. a lot of cutting and welding tack weld remove and replace tubes. my first there's a tri-yy. basically same thing for the second one except I couldn't find Big block mopars so I had to make my own flanges got a piece of half inches all I...
413
8.3 compression
5 Speed manual trans

Every time I go to a bigger motor I seem to get it pushed further into the cab and lower to the ground I have lots of room up front. 15" crank pulley to radiator.
