Thanks and I will work towards that after these current changes are done. I may have a couple 1850s laying around to possibly steal the blocks out of but not until after the radiator and water pump pulley fix.
Side question. There seems to be debate as to manifold vacuum or port vacuum for vacuum advance. Books say port vacuum was only a change due to emissions and it will run cooler with manifold vacuum adding timing at idle. This is how my hot rod is because the 950 Holley 3 barrel has no ports. Works well in that.
