The pistons depend on the rods you have.
Compression height is the difference.
I like the Probe versions... they are cut for both TFS TW and other inline cylinder head valve diameters up to appx 2.100".

A custom camshaft is going to give you the most performance, especially over the FMS cams. There are a few mentioned in the Ford Forums... I use Camshaft Innovations.

The intake you listed will be the performance limiting part, along with the FMS cam if that's what you choose.

These are my opinions... but they are based on facts.

I agree, there's better choices for a stroker than the Ford cams. That will depend on what you want out of the engine, is it going in a daily driver, a weekend toy, a strip car, I'm guessing a street car.
And a ported Cobra would be borderline, you'd do better to go with an Edelbrock RPM II, TFS Track Heat or the R Series, a BBK R Series, or a Holley Systemax II intake. With such an engine, you'd be bypassing the airflow capabilities of the Cobra.

alright looks like im gunna have to booty the ford cam and manifolds. im looking to have kinda like a weekend toy that i can take to the track every once in a while. i want as much performance out of it as i can but i want somthing that im not gunna have to rebuild so soon. as for the pistons i had my eye on some probe pistons but might go with srp. i want a cam that will have some good bottom end because i want to leave in the stock 3.08 ratio. appreciate the advice guys.

from the research i have done...i found out that the 331 storoker is much more reliable and you can get the same amount of power out of it...supposidly you have to rebuild a 347stroker around 70k to 90k...just wanted to let ya know!

A 347ci sbf at 90k miles in 1320' increments turning 7200rpm is a damn fine accomplishment in my book.

Anyone who tells you a 331 will last longer than a 347 has;
1. Never built a 347ci sbf.
2. Never built a 347ci sbf correctly.
Remember... there are engine builders and there are engine assemblers.

As for a 331ci sbf making the same power as a comparably modified 347ci sbf... I'd take that bet.

Will you please post up the references found in your research? I am interested in the capability and accomlishments of those shops/builders.

Back on topic.
If you would like references for some badass performance parts and the people behind them, I'd be more than happy to post them up for you.

The value in Probe pistons... they accomodate TFS TW as well as other standard inline cylinder heads up to appx 2.100" diameter valves.
