So on a 70 440 hp build back to stock. which pistons would you guys suggest without breaking the bank. looking to stay at 9.5 - 10.5 compression so which ones would you run in a street car? motor is 40 over std 906 heads thanks abe

Speeed pro forged http://chucker54.stores.yahoo.net/440comdis20s.html KB also has forged either way $100 is more than Hyper/sterling pistons the way to go in MHO. http://chucker54.stores.yahoo.net/icfopi.html get the right pin size 1.094 I presume.

I would say "avoid" if possible. BREAK THE BANK ? ...why try and cheap-out on something that is not that much more money and on something that is so hard and expensive to UPgrade to ?? IMO ... IF POSSIBLE .... use cast or forged.

I've (& others) have beat them almost to death & I've yet to see 1 piston fail. ~.003 P/W & that's it if you can get a CH to suit you live every 24 hour block of time like it's your last day on earth

Mine is a 440 and his is a 400 and we run them as hard as you can. 63 has been on the road 4 years and my sons Dart with the 400 over 8 years. You just have to set the ring eng gaps right. Ron

Ron I've used KB's in my Slant for many years with no issues. I've even sprayed them. I open up the ring gaps even more than they suggest and have had no issues.
