Wanting to know how difficult it is to swap 4.3 out in my 1995 chevy s10 blazer, like tranny bolt removal and anything that might be of difficulty that may require specially tools. its also a 4x4

USA spec car or?
no engine told of many
the VIN + RPO list at GM shows what is there.
RPO is the as built list from GM.
2000 blazer you meant S10 blazer right>?
this engine L35
1996-2002 - 4.3 L (262 cu in) Vortec 4300 L35 V6, CSFI,
if both are L35 sure. (assumes sub component accessories can be swapped too. if need be. (bolt on parts to engine)
engine swaps have 3 paths
block only
block and heads
block + heads and all parts attached.

it has to fit bolt on, and the PCM IN THE TRUCK (BRAIN)
must like all that, in all ways. displacement , firing order, and all accessories, related to EFI the alternator and HVAC parts.
IMO. join a real chevy forum that does this?
see all the pit falls there, our web site is not about swaps.

they should swap just fine. 1996 and on are interchangeable. 1995 could go either way. 1994 and older are interchangeable.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

once you have all the parts for the swap it should be a direct bolt in. its the v6 right?

you will need to have the oil pan on, its pretty tight when you put in a 350 ,also a 3" body lift will make things alot smoother godbless

yes can be done but will need some mods and programming ------and an s-10 trans tunnel will need mods --------this is a full size but shows some of whats needed for swap also check the s-10 forums for better sources on mods ------https://www.motortrend.com/how-to/129-1004-1977-chevy-4l60e-to-4l80e-transmission-swap/ -----https://www.motortrend.com/how-to/1307-4l80e-transmission-swap/-

No its kind of specific I have a 96 4.3 s10 blazer you can stay with in your model years early 95 and back later 95 to 99 are the same You need to stay with in your year range and im not even sure early 95 would work for you Ckeck the vin #with the dealer all the information is with in that # But 86 87 i don;t think will work all you can do is check good luck

you have to take the flywheel cover off. There are 6 bolts to that, one of which is very difficult unless you have the right tool.

well pulling motor and tranny would make it easier in respect to fighting with the tranny bolts but in order to get the tranny and motor out one shot you need a good 2 to 3 feet clearness of the ground and will need to take the radiator and support out to get it out.

tranny bolts aren't that bad except for the top one and if the tranny mount is removed and the tranny hanging down you can get at it with a long extension.

i do it that way because i have a lift and air tools. not sure what you have and what your capable of but it will depend on you situation what is the best way!

if i was doing it on the ground i may take it all out one shot!

good luck man. please ask any more question you have

remove drive shafts remove cross member, and transfer case mount remove transfer case then remove tranny there are 6 bell housing bolts that hold tranny in 15 mm i think and 2 trany lines if its auto

Installing the full-size Blazer trans into the S-10 would be safer. As long as they came off of the same size engine then yes, they will interchange. But.... the trans off of the S-10 is not built as strong as the trans for the full-sized Blazer, clutch capacity is less, band servo may have smaller apply area, and torque convertor stall speed may different enough to set a "code". Towing capability would be compromised. I have no idea what you meant by the "bolt for the plate".
