Hey,Just need some info on a set of pistons I've found for 250 bucks.They are SpeedPro 2293 forged with dome!Any specs would be appreciated!Thanks

From an Ebay listing:
NEW OLD STOCK TRW FORGED PISTONS.

PART NUMBER L2293F STANDARD BORE.

THEY FIT 383 CHRYSLER

.368 DOME

5/64 5/64 3/16 RING LANDS

1.915 COMPRESSION DISTANCE

12.42 TO 1 WITH 78.5 CC CLOSED CHAMBER HEADS

11.05 TO 1 WITH 88 CC OPEN CHAMBER HEADS.

They have a big dome with a "fire slot" for the spark plug, definitely old technology.

One other thing: They are heavy.

heavy forged piston that is called a 12.0 piston in a 383 , but probably closer to 11 depending on the head used .

Keep looking ...

Theoretically, I agree. I'd check Mancini to see if he's got Diamonds on sale. Also, does Probe make a piston?

The 383 should love to rev and if you can take 100 - 150 grams out of each piston it'll live up to its promise. It's worth the extra $. Also, the pistons set up the rest of the engine and they're worth spending more on to get what you NEED.

Ok thanks and i will just keep looking

Mancini has 4.280" Diamond flattops for 3.75" stroke 6.358 rod 383 blocks for $499. Are you sure you don't want a stroker?
You're only one crank and $249 away!
