Fastest Duster on stockish suspension?

Your mouth is dribbling bs with make believe combinations. I haven't seen anything but TF heads on bb mopars since they came out, the last one was a 383 with a 4.25 crank, it made 765 hp with out of the box 240 TF heads. I don't know why anyone would use Edelbrock heads I've seen more dropped valves, valve seats and junk castings that Edelbrock would not stand behind.
I suppose with your thinking the NASCAR builders put less of a motor in for restrictor plate racing.

I am deffo in the “old iron 440” club myself.
I have a 71 Gtx that will be an all iron 440 for fun and some track days!
What will it run is neither here or there, it will be what it will be, lol...

But I also want to run Tens again, not for me but for my Mopar mates who have yet to have that thrill...

So being a pensioner with a piss-poor budget, it’s gotta be a ‘cheap as chips’ 10 second lightweight Duster on springs lol...
