The timing probably could do with some tuning. I'll be able to check what it is set at later this evening and report back.

No heat shield, just a riser.

That forum thread was FANTASTIC! So much information and could possibly be my same issue. My Holley is new and I thought by going with a known good unit I could eliminate other problems I was having at the time!

The blades for the fan are mostly within the shroud. It is a single piece aftermarket unit that seems too close for my liking. I have a two-piece shroud on my other Blazer and it fits nicely.

edit: looking tonight I did see that the fuel line from pump to carb is tucked between the block and alternator with little room to wiggle. Tomorrow I will remove the alternator and route that better, and I’ll also check what it is currently set on timing. Thanks again, everyone!
