I have limited my future engine swap to either the 3.4pr or the 3400 out of Alero's / Grand Am's. Putting difficulty aside, what swap would you do and why?

3400. lighter, newer, no custom tuning, more power, better fuel economy.

yeah - if you can - do the 3400 SFI - it has the highest output

Ok so how much would a 3400 swap cost if someone else put it in for me. Would a relatively low miles 3400 swap with labor be more than $3500?

FYI, a 3500 is supposedly not much more difficult, but the engine itself is significantly cheaper for a low mileage unit.

Having said that, also an FYI, the stock 3400 heads will out flow ANYTHING you can do to iron heads.

I had a really good thread on the 3400-3500 swaps, with a lot of info in it. I will see if I can dig it up for you.

Edit, I found it

Having someone else do a swap for you is not a good idea. Most of a swap cost is in labor because it takes a lot of time to get one running right and each one is different. And when it eventually has problems you'll be dependent on the person who did that swap for you to fix them. That's not as simple as it sounds. What usually happens is it sits out in the back lot somewhere until whoever feels like it gets around to working on it again, weeks or even months later, and you keep getting the "nother couple days" answer when you ring them up to find out what's taking so long.

Most people can complete a 3.4pr swap successfully using my instructions. If you're not up to the task of welding, fabbing, and rewiring, I suggest doing the 3.4pr because it requires none of these. If you don't have the skills or friends to do it yourself, just don't do it at all.

post 2000 large-port 3100, 3400 or 3500 alllllll day
Any of these are pretty simple to install, are lighter, make more power and get better mpg than a 3.4 camarobird engine
