I'd go with the pre machined 360 and flip the 340 block if it was me. It is worth way more than your paying for it. On second thought, I do have a brand new set of forged pistons for a .040 over 360/410. 70 Dart Swinger 72 D-100 440 shortbed 76 Pinto, 68k 21mpg!

I sold the 340 for what I paid for it and then sold the parts on the 360 I wasn't going to use and came out ahead. 360's are easy to find and cheap. I'd prefer to see the 340 left as a 340 for someone who needs it for a restoration. BTW I would take a mild 450 hp stroker smallblock over a 450 hp 340 or 360, especially on the street. You can run less gear, cam, and convertor with a larger engine and still go just as quick. The bottom end power of a 4" crank smallblock is a real eye opener.

Cast crank and lite pistons/rods make it easy to internally balance with no mallory. I used ported EQ magnum heads on my 390 and I figure it should be right at 450HP...

Should have been worth more than $40 unless there was something seriously wrong with it. I have a running 340 (bore unknown) in my dart now, and a 360 shortblock (standard bore) that I bought for $100. My plans are to sell the running 340 to help offset the cost of building a 408. 1970 Duster 340 clone

Couldn't get rid of it. I offered it to a couple guys here for $200 + shipping, offered it for just shipping, then tried giving it away locally.... nobody wanted it. Soooo, I took it & a cracked 383 block to the local scrap place. It was decked & line bored. The cylinders were bored .030 over, but had some rust. So, they would have needed to be cleaned up to probably .040. 1968 Plymouth Fury III 4-Door: 12.79 @ 115, 60'- 1.93 (Hey... it's a Cruise ship... what do you expect?!) Famoso Raceway, 02/08

Just a couple years ago I found my running '68 340 with X heads on Ebay, complete from oil pan to intake for $500. Then again, just last week we bought a complete '88 360 with 727 trans for $99 off Ebay. Even has a carb, distributor, air cleaner, mini starter, power steering pump, clutch fan, and all the brackets. Maybe we're just lucky. lol
