I hate those umbrella seals. Mine crumbled to bits after only a couple of years. When I got my heads done up, I got them to machine the guides to suit press-on Viton seals. Never had to think about them since.

But these are mahle maybe better and look at the difference between 400 rod and 351c808041159b4be3ba90c0a237c8f7680f.jpg8193f17714648f99149b1bec6060a70c.jpg

There is no way around it ya have to buy the expensive forged flat tops 1.700 comp height

I think it pays off in the end... If I had my time over I would've yoinked the hypatec rebuilder pistons for a decent set of zero deck flat tops. 17 down the hole is a lot on a little 302

That and an open chamber... Compression on them is total poo. No wonder they were considered a slug. I wish I'd gotten on the bandwagon a long time ago and built up a good healthy streeter... I like nothing more than to see an orphan engine punching above its weight.

You can also bush the 400 rod and use clevo pistons as say a set of sealed power aussie flat tops have 1.645 comp height normal 400 piston is around 1.630 so your 15 thou up the hole already then shove the aussie 02 heads on it and bam around just over 10.1

But being that far down the hole still, the closed chambers act as opens. Not the end of the world but you lose the advantage of actual open chambers with their unshrouded valves, yet don't have quench action like a proper closed chamber does.

The latest 400 forged pistons come in many cc for juggling your comp but they are very nice and pricy too by the time you land them cheapest is about $800 au

That's still not too bad for a low volume, speciality piston. Remember when a good set of forgies were $1500 maybe 30 years ago?

Silvolite part No. 3330, Australian Ford Cleveland. Comp height 1.720", bore 4.000", 0.912 pin, unsure of dish CC's tho, may work with bushed 400M conrods

https://uempistons.com/series-4280-silv-o-lite-australian-ford-351-5-7-3330.html

@CHESTNUTXE there was also the possibility at these pistons (above) with 400M rods bushed, just saw a STD set on US ebay at $133.55usd

 

From memory THOM also had EFi on his Customline's Clevo with downdraft ITB's.

& Back when I was looking at Holley's Terminator X EFi Kit for 5.0 Windsor, I figured it would run a Clevo if you used a Holley Dual Sync dissy & had a intake modified to fit injectors.
