Looks like a GM series II 3.8L next to your sbcHavent had a chance to do much on this as yet the joys of being self employed, but finally got the holden motor out the other day. Dropped that off today & picked up the 305, now the giant jigsaw puzzle begins. Bought a flexplate & bolts plus top & bottom pulleys today, got bell housing bolts coming over night. Going to write up a list of all i need as pretty much no bolts for anything, got a holley blue pump in another deal so i'll use that.
Got a new 450 mechanical secondary quickfuel slayer carb for it, hei dizzy & eldebrock manifold there. No idea if the headers will fit till i get the engine in so time will tell on those - have to cut the made up mounts off the front crossmember as well & get the bottom mounts bolted up so yeah bit to do but good things take time
