4.3 to 5.3 swap
I have a 2000 4wd with a 4.3 liter engine and would like to swap to a 5.3 liter besides the harness, computer, and accessories what else would be needed to complete this.

Re: 4.3 to 5.3 swap
Besides what you have already know, you will need (from a V8 doner) Throttle cable,cruise cable,engine mount stands,Fan stroud,radiator hoses,fuel lines, And the biggest thing to consider is the trans the converter spacing is different and V6 4l60Es only have 5 3-4 clutches VS 6 in the V8 version. your best bet is to use a 5.3 trans & it has to be a 4WD trans because of the different out-put shafts. All in all the easiest 5.3 swap.

Re: 4.3 to 5.3 swap
sorry for off topicidness, but is this a similar situation from going from a 5.3 to a 6.0? or is there more to that?

Re: 4.3 to 5.3 swap
The early 6.0 had different cranks (99 & 00) than any other LS based engine.
using a late model 6.0 all you really need is a long block The computer & intake are the same between the 6.0 and 5.3.(The 4L80E 6.0 computers are different) Dont count on your stock 4L60E to last long with a heavy foot. |

01-07 6.0s have aluminum heads, and the crank spacer for the 4l80e can be removed and mated to a 4l60e Everything off your 5.3 bolts on/hooks up to the 6.0, get the computer tuned and drive. But your 4l60e will not like it very much. Look into a few basic upgrades for the trans such as a shift kit, and corvette servo to give it a little more holding power.
