1970 DODGE 340 SIX PACK vs THE WORLD Richard Holdener

Ya. he didn't want to do many runs or touch it much without the owner there, not bad 326 hp without being dialed in.

Richard Holdener almost always runs headers and electric water pump even with less cr and mild cam his did 370? hp, possible Nicks with tune, electric water pump and headers would of come close to Richards numbers. Don't know if cr mattered much since blueprinted 9.5:1 vs stock un blueprinted 10.5:1 would probably be similar, Guess depends on the Ford and Chev one's he's comparing to if they were blueprinted to stock cr.
Would be interesting to see what that engine would produce in the car with some tweaking including the distributor curve & carb jetting. I know the owner wanted a "stock" rebuild, but head porting is still leaving everything else stock but improving the flow. That alone should help the numbers some!
