Got myself a 71 Duster a couple of years ago, seller had no clue of engine internals or nothing else but I got a good deal and bought it. Haven't had time for it until now.
340", Eddie heads, Torker intake, expensive red dp carb, newer crap MP distributor, Hooker Comp headers... that's what you can see.
Fiber glass hood and bumpers, subframe connectors, full interior, drag radials... Will see mostly short trips and some visits to the 1/8-mile. Stalls around 3,000. Would guess 3.91 gearing. Manual valve body.
Started it and it run. Drove it home, 7 miles. No noises but run like a pig.
Did a compression test: 15-154 psi except for cyl 1 with zero. Stamped steel rockers. Exhaust pushrod stamped its own hole in a rocker, his brother intake had an s-shape so I pulled the engine and then the head. Looks all good otherwise. No damage on head, cyl walls look good. Pistons all the way up to deck.
Single springs seems a little strange with that high lift cam. Will check pressure open and closed.
Got a set of 273" ductile iron rockers from a friend yesterday. Will check lift and duration on cam tonight. Will also pull pan and see if there's something there I don't want to see there.

Have no experience of 340's so looking for advice. I guess to much lift and high revs for OEM rockers and 273" rockers will do?
What duration, lift and LS would work best with the combo above?
Thanks!
