Re: 1961 GMC 5500 Tilt Cab Project
will the 4bbl be much different than a 2 bbl on that motor?
Also, it runs a little rough, but the plugs and wires look way old.
gonna do a normal tune up and then plan on an HEI, and holly.
I don't believe a have a Magnum manifold...
Are those hard to find?
Also, if i would see big gains in the 4bbl, which one would be the "best"?
Thanks again for the advice, i truly appreciate it.
