Those TBI 350's like in that pickup above are great ones for something like this. They go 200K miles regularly. The EFI keeps ring wear to near nothing. Find a decent one and swap in. Heck...they even have the good Vortec heads if you get the right one.

I believe he means 355 cu inch engines. Which would be a .030 over stock bore. Some folks think changing rod length changes cubi inches. It involves changing the piston too which results in a net zero change. Stroking an engine involves changing the crankshaft to a longer stroke which is a totally different thing and gaines cubic inches of air volume
Hence a 350 with a 400 crank gives you a 383....
Some folks heve the machine shop change the rod which requires a new piston which most will over bore and then tell the owner they have a 355 now and the mistakenly believe the rod changed the cui
Completely unfixable 2 holes in the block shame shame well if anyone wants to buy a greenwood kitted 79 be my guest needs and engine lol
Ok, now that we know that lets move on. You live in TN, land of Rednecks and junkyard Chevy engines. What is your budget to get the car back running? Or the real question is, is this your car or one you were looking at?

Probably a moot point for this thread, but making a 383 also required a considerable amount of clearancing.

This was true a few years ago...but the last three I built required zero clearancing....Scat and Eagle both re-profiled their rods to clear the cam lobes and pan rails.....
I wouldn't build a 383 for a long time because nobody would pay for the clearancing.....then I was told that the rods were fixed and mocked up a One Piece main seal block with all 8 pistons and no rings with a Hydraulic Roller cam that had a standard base circle and everything cleared by a mile....

Good to know. It's probably been 20 years since I built a 383.
So what does 355 mean in your context??? You referenced a stock 350...so the conclusion (obviously wrong on my part) is that 355 was referring to cubes.
So once again...explain 355 to us in your context. Willing to learn how the "355 folks" think and look at things.

goodness.
use 6 in rod and it is known as 355.
what is hard about that.
like I said ask 6 in rod guys.
sounds like some here use bored over cubic inches when someone asked what engine you have.
nuts

It's not hard, but it is incorrect. Please provide a reference to someone else who is calling a 350 with 6" rods a "355". I think we are all very curious how this misconception got started.

its a designation.
I didn't name it.
Been around since late 90s.
L-82 and L-48 are designations.
The only wrong thing is your thinking

No, it isn't a designation. You've gotten yourself confused or been misled by someone else who is confused. L-82 and L-48 are codes used by the factory to designate which engine option was selected. "350" is not a designation - its the number of cubic inches the engine has. "355" is a bored over 350. It has 355 cubic inches of displacement. It has nothing whatsoever to do with rod length. Rod length doesn't change engine displacement. Putting new rods in doesn't suddenly make it a 355. Putting new pistons in with a .030 overbore does. Since you cannot change to a 6" rod without new pistons (due to the compression height of the piston), and since new pistons are generally installed with an overbore, you end up with a 355 by way of the overbore - not the rods. Putting in 5.7" rods would still result in a 355 by way of an overbore. Putting 6" rods in a stock bore would still result in a 350, despite the extra rod length.
