I’m not a mechanic, but was wondering....

[Ult-Jim]

At work currently have engineers that have striped the top half of a 12 cylinder 3,000hp marine turbo diesel engine in two days. So I was wondering.... how long does it take a trained mechanic with all the tools and lifting gear to gut an Ultima engine bay with an old V8, gear box and all the trimmings in preparation for a fresh LS3 / LS7 install? Aplogise in advance if a stupid question, just day dreaming, on watch, stuck in port. Ult-jim.

Taking it out is the easy bit and would take about a day.

Designing all the new fuel system, oil system, A/C plumbing, installing it, taking it back out again when a trial fit of the engine shows all the places it clashes, and so on.
Could take a week or more of solid work. This is assuming the engine already has all the brackets etc for the ancillaries.
If you go away from a Factory supplied package you could likely add another week trying to sort things like clutches, release mechanisms, starter motor, A/C compressor etc.

Even then you will still need to do all the wiring.

Lots of forward planning required.

Thanks Steve for your answer. Was considering the idea of purchasing an older road orientated car within my budget and then investing in an engine upgrade and more track biased spec later. I can see the labour costs building up if the job is to be done properly. Ult-jim

I get my wife to help me lift the clam off and then 2 hours and I have the engine out of the car by myself in the garage. 3-4 hours to go back in though.

I'm slow, 8 hours.
