Was wondering if anyone could give me some info on pistons for a 408 clevor. I have a 72 windsor block my heads are D1AE-GA my cam is a 280/288 553/572 it is a 289/302 cam so probably a little more lift than than since i will have 1.7 instead of 1.6 rockers. This is going in a 1968 mercury cougar 3500 stall probably going with 3.50 or 3.73 gear would like to keep compression to maybe no more than 10.5 since this will be mainly a street car. Was looking at the probe industries kit with the -22cc reverse dome piston but i don't know if these pistons will work with Cleveland heads. I called them and they were suppose get back with me but they haven't yet. Was hoping someone could point me in the right direction. Any info would be greatly appreciated.

...Probe doesn't have an off-the-shelf Clevor piston. You'll also find that to be the case with a lot of other piston manufacturers.

You do need a piston with around 20-22cc dish volume.

You have a few choices here....

1. Go with the Probe pistons made for a 408W combination, buy a fly cutter and cut them yourself for a Cleveland valve layout.

2. Go with a custom piston.

...has some Clevor pistons for your combination in an 18cc and 30cc arrangement.

That would give you around 10.25/9.25 SCR. However, they are about $700 a set and require a more expensive ring pack.

Thanks a lot Brent that is exactly what I was looking for.Another question I have is intake stuffers. With the added cubes are they needed. I may even go 427 since its the same money I plan on turning around 7k rpm and it is a street car

...probably the closest you'll be able to get is about 425ci. That's a 4.060" x 4.100".

With that displacement, I would not use the tongues...

Do you have any parts yet at all?

...that you'll need more cam to put the peak at the same spot with a 425-427 as it would be with a 408. More displacement requires more duration for the same peak.

No the only thing i have is the block and heads.The cam is in the 302 that is in the car now i can buy a different cam i just want to make sure i do this right the first time because money is hard to come by when you have two kids in competitive sports year round LOL the 408 seems to be the engine of choice these days and i am not to worried about a few cubes just trying to save money were i can. By the way is DSS decent quality as far as there cranks and rods there kit is about 2k which is about what i was figuring on

....but I would use Scat. Sometimes these companies buy from manufacturers and relabel, but I'm just not sure who they relabel. They don't make their own, that's for sure.

If you need a price on a rotating assembly, I would love to give you a quote.

I haven't had that much experience with 'em, but Flatlander racinghttp://www.flatlanderracing.com/index.html sells the Probe SRS pistons that should work well for your stroker, and for a great price. Brent, Barry, Mark & etc. would probably share an opinion on how good they are or aren't. They also now sell Icon and Auto-Tec pistons too, which I have not looked at recently. I can say I got some custom Auto-Tec/Race-Tec pistons through Tim Meyer, and they look like really well built parts, which stands to reason, considering who founded and runs the company. They were a real reasonable price, and Tim worked with me to get all the slightly weird parameters I wanted.

Having discussed this same deal in 408 and 393 with Scat, there are rod length, custom piston and balance issues. You could be money and hassle ahead to let an expert put a package together for you. I'm about to do the same thing as you for a new engine, looking at 408 with D1AE heads. LOL
