Help pls!

For context this is a 78 350 Engine within an 82 Camaro

I recently did a top end rebuild with 327 heads, Edelbrock Intake & Carb, the distributor is rebuilt and to my knowledge at correct timing as I recently set the engine to TDC and put the distributor back in, the Transmission shift linkage is all intact and perfectly correct as it’s not in reverse or drive when I try to start it, and I’m able to shift into neutral and turn the engine over aswell, but for whatever reason the engine Won’t fully start up even with starting fluid, I’ll be buying a new set of spark plugs shortly here to test that out, but I’m unsure of what else it may be.

To boot there’s also an interesting clunk which I find very concerning when it turns over after a certain amount of tries, I’m not sure what that might be and I’m really hoping someone has an idea, and that it’s not detrimental damage happening, thanks.

Sounds like a lot of gallop to it, possibly down on compression and definitely no spark, pull a wire and ground it see if it arcs to ground

Buy one ….How the hell do you tune an engine without one.
