Yes, that is one way, the other is 4.030" bore and 3.75" (like a 400 crank) stroke. In the case of Blue Print new blocks are 377 Cu in - 4.000" X 3.75"383- bore 4.005, stroke 3.800

Seems straightforward enough.hey guys, doing a swap from a 305 to a 350,
So it could have a 3.75 stroke crank, and therefore could be a 383.it’s a .30 overbore with upgraded internals so technically a 383.
The GM "crate engine" 383 is built that way--or close. I thought the GM crate engines had the standard "4-inch" bore. Someone at GM apparently thinks "383" is magic. They're trying to capitalize on the aftermarket 383 mystique. The aftermarket 383s started out as a "cleaned-up" (.030-over) 350 block, with a cut-down 400 crank crammed into it. Then the aftermarket started building new 400-stroke cranks that already had the 350 main journal size.383- bore 4.005, stroke 3.800
That's the way I understand it. Remove 305, install .030-over 350 with "upgraded internals" which could mean 3.75-stroke crank...but apparently doesn't.now i lue of that. did you swap to a 350 block then?
Gear pattern is the same. OD, 3, 2, 1 on the shift indicator. Even if they're labeled OD, D, 2, 1, you're getting the same ratios.As stated 700/60e/70e all have almost the same gear patterns.
They're difficult to work on, and even if you're a perfectionist, you're likely to have issues. Porous cases, fragile planetaries, and bad tech data are common. Not to mention it's at least four hours of labor to swap them out in your driveway. Then you need specialized tools and a full week to rebuild one. Never mind that there's no "everything you need master rebuild kit". There are so many parts that have to be bought individually, but you don't know if you need them until you inspect them, and that leads to a week of downtime while you wait for parts to arrive. That's the struggles before you find out if you have the temperament and patience to put it back together without nicking a seal, without getting a lip seal backwards, without forgetting where your check balls go, and with trying to get your teflon seals to shrink down long enough to get them into place.I am fascinated on transmissions and why it’s the last thing anyone ever talks about.
You're gonna need to change the PROM or Calpack or whatever so that it throws enough fuel for the added displacement.truck ECM is stock with a 305. I swapped to a 350 after my motor started knocking.
