Ironically I have never ever once had somebody asked me how fast my duster will go LOL... just by looking at it they know they better hold on to their nuts...
I did have a customer who sunk ungodly amounts of money into this 273 LOL.. hydraulic lifters and Harland sharp roller rockers LOL the biggest air gap intake and look look like the biggest Holley double pumper I've ever seen in my life LOL.. I came about helping him take the heads off because he had cracked one likely just revving it up in the driveway LOL.. the heads were almost stuck on by the black soot build-up from that massive carburetor.. I never could wrap my head around how someone could take solid lifters out and put hydraulic lifters in and take out Factory 273 adjustable rockers and put in Harland sharp roller rockers LOL...
