I have chance to get an ls1 with 4l60 tranny 150k miles, or a 6.0 with 4l80 with 88k miles. They are same price 2k with everything. I know some advantages on each, what are your opinions. Will be going in a 75 Nova. Thanks in advance.

6.0 with 4l80E

less miles
Stronger Tranny
You can increase displacement with boring
Better head selection
More power potential

No brainer

Agree about the 6.0/4L80 combo.

If I knew then what I know now that is the route I would have went.:yes:

6.0/4l80e is the same set up I am running. There wouldn't be any question. Low mileage buy it quickly.

6.0 is what I am leaning hard towards. I worry a little about the truck intake fitting under stock hood. Well, not exactly stock I am doing the 67 SS Chevelle hood louver and underside bracing swap, but it will not be like a cowl inducted hood.

Can I use accessories such as truck fan, power steering pump, alt etc. I know AC compressor has to be relocated. Anywhere make brackets for this?

Thanks for advice so far.

Here's a link (one of my fav's) for another LQ4 swap.

There are others here. Just use the Search function above and look in the 4th gen section.

IIRC, someone used the truck intake and even the top cover and made it fit with a stock hood. He had about 1/2" clearance between the hood and engine cover. Cannot find the link.

Novajay, Thanks for the compliment

The above buildthread is mine, I daily drive my nova and have 4,000 flawless miles on it since this fall. Send me a pm or ask me on here if you need any help whatsoever. I was able to do the whole swap while being a 20yr old college student! Just keep reading and researching!

for the sake of the power you will want to make, the 4l80 is the way to go. One of my buddy has a tuned 5.3 and within 1000 miles of swap, had to get his 4l60e rebuilt. if you do not get the 6.0, i want it.

I agree, I have the 4l80e behind the 5.3l. It's quite quick!
