Well a friend offered me a free 350 block so the question is, should I do it?

Take the V8. And know the feeling that if you every blow your engine you have a fun project awaiting.

Ya I'm taking the block and going to build it just don't know if I want it for the 951 or save it for something down the road. My 951 engine has over 200k on it so it's getting tired so the swap is very tempting.

Eh...what kind of "Free 350"?

There were a lot of variations of the 350CI motor, not all good. Many put out less HP than a stock 944! All will add weight!(we are not talking LSx here)

Reimu

No thats dumb. Old 350s are a dime a dozen, I wouldn't do anything older than a LT1.

Even then getting the engine is the easy part.

Arominus

Ls1 or bust. It's the only one that makes sense.

Lt1 350 block is just as good as an ls1 350. The iron block is only 45 pounds heavier than a aluminum 350. Plus the number of performance parts for a small block is unlimited.

The 350 engine is late 80's or very early 90's. If i do put the motor in it won't be stock it would have to be at least 350+ hp. I also would turbo charge the engine if possible. Personally I like the stock engine a lot, well built and lots of potential. I plan to keep this car for a good 30 yrs unless it gets totaled.

blown design 4 banger , cheaper-better ,win-win situation

I have considered that direction as well, build would be around the same price either way but keeping the car for so long it would be better to have the porsche motor.

I have never figured out why someone would want to put an old engine with crappy fuel miliage into a Porsche. Use a LSx or do not even consider it. They are making very good engines today that you could use so why would you want to go backwards, you already have one of the best engines from the 80's.

By the way, there is no reason to do a poll. Just do the research on failed dreams and junked out 350 conversions that never get completed or ever turn into a reliable driver. For every success you will find 20 failures. It takes a lot of skill and money to do it right so you have to seriously ask yourself if you really possess the skill and money to do it. Maybe you do? I am always suspect when I hear the catch words like 'throw it in", "change it out" "force it" or in your case "swap" it in. Like someone is changing ice cream flavors. I would take people much more serious if they would tell me they are going to "fabricate" putting a engine in.

Technically true but the rest of the engine is not. It would be a waste to do an iron block LS1 anyway. There are plenty of all aluminum block LS motors out there.

I had a 2007 C6 Corvette and that was one of the sweetest engines ever. 400hp/400tq and with the 6 speed manual, 32mpg at 70 miles per hour.

Research is done, I have been considering this route for 2yrs now. I did a poll for my curiousity not to make my decision. I personally like the 4 cylinder engine in the 951, except for the interference design. Which in that case if I have to rebuild it will be the main thing I change. I also don't like taking a classic car and mutilating it, but also these cars may never get the value and attention they deserve. On a side note most v8 engines have "crappy gas mileage", especially built in the 90's and older, newer v8 are a lot more efficent; I know my father's 08 corvette gets around 30mpg. The 928 motor's don't get favor in the fuel department as well. The swap idea isn't about fuel economy, it's about power and money efficency in the long run due to part availability/cost. The 944 motors are fully reliable excellent engines, it's the owners that are typically the problem, so I am not insulting or degrading the motor by any means.

If the engine is ever installed it wouldn't be for a few years any way. My 951 is my DD and I try to treat it well, I have new go fast parts for her on the way as we speak and this summer I will be changing a lot of gaskets, hoses and other items to ensure she stays running.
