350 Piston ??
I will be rebuilding a 1969 350 this fall #5 heads. What is out there for pistons? I have been searching for hours and find almost nothing but a flat tops which will make too much compression for todays gas and pistons with a huge dish. I'm trying to shot for 9.5 compression.
I did find a forged TRW piston that gets the compression about right but they are $66 each.
This car is going to be a cruiser/highway car do drag racing and no nitrous.

Hey Jag...I wouldn't buy the pistons until the engine is apart. That way you can buy the pistons that will give you your desired compression ratio. Just set the $$$for the pistons aside, then once the engine is apart your builder should be able to measure the chamber size so you get the exact CR you want

What's the part number for the Probes? I also have a 350 in my 71.

Hope this helps. They're .013 taller than stock so deck your block accordingly.

Short block has been in his shop over 4 months, and I want it back.
I can't believe it is taking this long.
I hope my probe flat tops are also .013 taller.

Check egge.com these guys have pretty good prices on pistons I haven't purchased any of their products but prices look good and they have some cool videos on their website that shows how they manufacture them on site.

I purchased a set of .060 over pistons from egge, they were flat tops, and they were great. I got free shipping, and great service!
I have also used the speed pro pistons with no problems, however, they have gotten expensive. At least, they are press fit and use stock rings.

Another option most guys overlook; it is not expensive (less than $100) to get a piston dish milled. So, do the heads, deck, then measure and determine the cc you want out of the piston. Mill a "D" shaped dish to correspond with the quench pad on the head.

Thats true, there are so many venues that someone can take, however, it still depends on the individuals budget and intended use. Example: building a resto, street, street and race, or strictly racing application. I thought of going with the chevy combo, but decided to keep it orginal since it is the oringinal w-31 motor.
