340.....360........ Just meet in the middle and toss a 350 in there and piss 'em all off
A 340 .060 over is a 350 if that makes anyone feel any better....

To the posters above who keep perpetuating the mythical 340 and all it's greatness, I say thank you. When I go to sell the 340 that's in my dart later this year, it's people like you that keep the prices up high. I will use the money that I've gained from people who've drank from the 340 kool aid cup to build my 408 using a roller 360 block that I bought earlier this year.
And yes, I was speed shiftin' a 340 four speed Duster 30 years ago...

Both engines are great performers. It boils down to how fast you want to go, and how big your budget is. I have both engines. Right now I am running a Mopar 380HP 360 short block, which is 9:1 cast piston, cast crank. On it I have the $500 Indy Aeroheads stock 340 castings with 2.02/1.60 valves and no machine work. The cam is the Mopar .508 hydraulic flat tappet. M1 SP intake, Holley 750 DP, MSD Digital 6 ign. This car, on the chassis dyno puts 300HP to ground at 5400, 314 TQ at 4600. Car is all steel, with 6pt rollbar. Car weighs about 3150 with me in it. On pump premium gas, the car runs 11.60s shifting at 5800. It will run 11.90s shifting at 5000. The 360 makes lots of torque, there is no need to buzz them that high, only maybe emotional need. This entire engine was brand new, from carb to pan was about $2700 including ignition. This is my second season of racing it.
I built my car to race in Stock Elim some day, with a 340. However since there are so many issues running against some of the newer stockers, I am going to do a 408/415 instead and go super street. Same ETs but cheaper engine.
My 340 makes 413 hp 398 tq built to stock specs . All that was done was a bit of cleaning up the heads ,new stock spec pistons and a mild cam .
This is comical, yet informative :happy1: Please, carry on :glasses7:
Never been a fan of strokers
What's not to like? Big displacement small blocks that make gobs of tire frying torque?!? Yes, please.

I have the print out from the dyno .

sure you have a dyno print - but of what 360?
This is an interesting discussion, especially for me since I made the decision to put a 340 in my 73 Duster. I thought about a 360 since they were easier to find, but I decided I had to have a 340 because that's what would have come in it in 73. I took a chance on a motor at Carlisle last year and paid $850 for a 73 340 motor that was mostly complete. Not knowing then what I know now (and that still isn't much of anything), I didn't need most of the stuff that came with it. It came with all of the throw away things (like pistons and cam and stuff). At least I got heads, a crank, an oil pan, and the caps out of the deal. I have an intake, but we're going to put a more modern one on when it all gets said and done. Sometimes I wonder if I should have just gone with a 360, but the decision has been made and what is done is done! If I blow this one up I might go that route.
As part of the build, he's had to bore it 0.04 over. He wasn't sure if he could find pistons any larger if it needed to be rebuilt again (he didn't look for them since we didn't need them), but, from this thread it sounds like I should be able to find pistons 0.06" larger for it? I don't know if it will be an issue, but I would like to know in the event I need the motor rebuilt since my goal is to drive it fairly regularly.
And Stroker , WGAF about Herb , what you got ? When it stops being fun , it's work , I'm retired , **** work . I bought the car to have fun with my son , not to be competitive , been there done that in business.
