Nothing like hearing a new engine run for the first time… congrats!
I have a 4 barrel TB also and you can hear the air rushing through the IAC valve at idle. I’ll be curious to see what adjustments you make to quiet it down.

Finally some pics of the completed engine and engine bay. Still have a bracket I need to make for the heater hoses and breather hose to attach to the fender, but other than that and a cold air setup that will enclose the air filter to the cowl hood, it's pretty much done. This is as clean as I could get it considering all the new extra wiring for the Holley EFI, AutoRad electric fans, and the few extra hoses for the fuel line return and breather.
Should be able to post a video of it running this weekend.
A little bit of old school with a little bit of new.
