And was just a .060 over 360 correct?Of all of them that one was probably the least cost and effort for the results obtained. J.Rob

did you buy them from Mancini when they were clearing them out a couple years ago? I wish I would have grabbed one! Are you wanting to get rid of one of them?
Car is stock except for a MP 284/484 cam so limitations will be intake and exhaust.
Thoughts on head limitations with this size engine? I don’t think too much given the fact the 360 uses a lesser head.
Hey Cliff. My thoughts on the cylinder head situation are at a stand still due to lack one thing, answer these questions to shed some light on the matter.
What is it you want from the car?
How heavy is it?
What trans, rear end ratio and tire size are in use?
How thick is the wallet?
What I mean by the last one is, can there be new cylinder heads in the future? This can be a pricey expenditure if the wallet is on the thin side.
Also, even stock small heads can perform great if you’d not pushing the heads performance level. Like looking for 575 hp from a stock port and valve 1.88/1.60-360 head. It’s just really feasible or wise to do so. Unless this is a FAST car bracket racer?????
find me a made in USA MP crank and i'll buy it , hate spending money on crap made in China , would spend double to have made in US products any day all dayI wont spend that on ethanol for a month.
I think Tom Molnar has the nicest ChiCom cranks available… Mine is a US made billet deal from MP Performance but Molnar will walk you thru the whole deal. He is also a buddy of one of my machine shops.
Good luck on your build.
Tat is a great time for a stock 340 what tires out back to run a 13.8 , best i ran was a 14.01 @99mph with 235-14. bfg tires and stock engine smoked the tires trough 2nd gear .My comment on numbers matching is just that....no one should really care. But, the Chevy boys have bled over into our hobby and now everyone wants to get wet about matching numbers. A 340 Dart is a 340 Dart, no matter if the numbers match or not. I can live without the snobbery of numbers. I do place value on a period-correct engine with the proper casting look and accessories....I don't like a 1978 440 in a 1968 Super Bee because it start to look wrong.
My 70 Dart Swinger, 1990-ish. I bought this from the original owner in 1983. 132K miles, loose but not worn out. 727, 3.23SG, buckets, console, no AC. Bone stock mechanicals, ran 13.8's in the quarter on more than one trip to the drags. View attachment 1715669763
Do we have past posts for all the possible combinations using LA blocks & cranks ?A 4.040" bore and 3.58" stroke makes 367.1 CID
It is possible to get a good crank from China. The problem is ether the manufacturer hasn’t gotten the note to make sure the part and material used is quality to meet the spec or the buyer didn’t request the quality spec needed.find me a made in USA MP crank and i'll buy it , hate spending money on crap made in China , would spend double to have made in US products any day all day
Great article and thanks .Any love for a 373? Yes! I have quite the affinity for this 371 built in 2011. Probably the best bang for the buck IMO of all SBM's at this power level. I did it with a very simple 360 .060" block, 3.58" Eagle crank, Scat 6.123" rods << Doesn't get much simpler or cheaper than that. J.Rob

..it's not the chevy guys, it's the collectors that require numbers matching or original parts.The big block e and b bodies can bring six figures and you would devalue them by using wrong or odd parts on these cars.
I don't think Darts and Dusters are collector cars.They are economical to build, look great, bring back memories and go fast and that's enough for most. Build them to please yourself. I still like them original appearing though...but i'm an older member and lived through the 'era.
(I forget the stroke of that crank.)
Funny you should mention the destroked 340 to 5.0 litres , i was thinking about doing that , having an engine i could rev the crap out of , might be the way to go , as all i have now is a block heads and intake , how hard would it be to get 400+hp out of that destroked 340 . I'm looking for something different that if driven with a light foot like highway driving will match the mpg of my 340 about 22 mpg and pull low 13 in the 1/4 mile . i drive the car 120 miles a day so mpg matters , also ;l still like to have a bit of hp for some track timeThe below picture is out of the last MP catalog and I think it does not include the very short stroke crank for Trans Am racing where the 340 gets destroked to the 5.0 Ltr. limitation of the Trans Am series racing.
