What type of exhaust does your 273 have??? show some photos!!!
340 exhaust manifolds, Tti 2.5” head pipes, Summit Racing 2.5” header back kit and dynomax ultra flos. Sounds awesome to me, not too loud at 70mph ~3200 rpm with the 3.91’s. I don’t have any real revving on video but here is the cold start.
And warm idle
