Doesnt sound very wild to me...wild is bigger than 250° duration @.050 106° centerline and more than .550 lift @ valve with idle speed minimum 1100-1200 ,loose 10"converter a must maybe even throttle blade drilled to idle with manners ...that's getting wild But it does sound good and I imagine if it was warmed up even better
Oh yes I had the two speed power glide with a stall converter in my 1970 Chevy Monte Carlo first year production model column shift. I had guys tell me it was a th350 not so they wanted the powerglide for obvious reasons. My trans guy built it for me from original. It only shifts once so if you have one keep it short or long tail.
And warm and normal operating temperature. Get a Ford it will stay running and aren't a dime a dozen. SBC, SBC wow besides the 454 or 396 It's the 350.
It's a Briggs and Stratton all it needs is a blade. And get it to run. sounds week and unhealthy. The chrome and high rise are overkill. He probably wiped out a lobe on the cam cause this thing did not get broke in.
