Since this thread started I have picked up two engines, a 1968 340 block original bore except the machinist over bored one hole and it needs a sleeve. A 383 with build date 1969 complete 2 bbl engine from 70 Challenger. I also have a 1968 383 sitting in the 68 barracuda never fired. Now I want to stroke one of the 383s and replace the 360 in the Duster and use the 340 with the 360 parts in the barracuda. Whats wrong with stroking a 383?

383 at the shop now
I have the 383 from a 70 Dodge W-200 at the shop right now.
Going to follow the Carcraft article as closely as possible and drop the engine into a '67 Barracuda Fastback. So far spent: $20 magflux tested |
Just a thought..............
I have to take exception to the statement that using a 440 crank in a 383 low block could cause premature oil burning and other problems. Mother Mopar built this combo for several years with no problems. It was the 426 wedge engine. This considered, parts SHOULD be available now. This was run in NASCAR for a number of years too and they got all the power they could from the factory block and cranks. It was always a hidden secret for many Mopar racers at the strip too.
As for poor fuel dist.? Ever hear of a TM6? 7500 rpm's anyone? |
oil burning
Tarbabe-The concern rasied about oilburning is due to the large rod side clearance due to the narrower Chev rods (yak). I have been part of many builds with oddball rod combos and haven't seen one burn anything approaching excessive oil consujmption yet. I believe it is due in part to any number of things nowadays-proper cyl wall finish,ring technology,piston ring groove machining technology, etc-not to mention materials! Hope this allays any concerns J.

Good points Aspenj, and just one more to go with what you said. A lot of builders use low tension oil control rings for less cylinder wall friction to free up horsepower. This too, will cause at least a slight increase in oil consumption....................djs

The only Thing...........
that excessive side clearence will cause is poor oil pressure and excessive oil being thrown to the cylinders. This could be more than the rings could wipe down I guess.

this might be of some interest.
