[Amc-list] stroker pistons, rambling, was, Re:290 Questions

[Wrambler242@xxxxxxxxxxx]

Good tips Jesse!
I sometimes wish I'd have bought the built 290 a list memeber had up for sale for $400 a few years back.
Don't remember who it was, but IIRC he had built it then left it sit, eventually he either sold off the intended car or moved up to a larger amc engine. For the amount of work I've done on my 4.0L swap I could have put the 290 in twice! and had a rumbly V8.

Not that I'm disapointed in my 4.0L

Going back to that, bigger is better thing.
Rumour has it that KB is going to be putting forged pistons on the shelves for 4.0L's!
Some of the guys over on the stroker list have gotten emails from KB's tech stating that they are about 2 months away! That prolly means 6-10 months, but better late then never!
   The request was for stroker pistons that gave 9:1-1 Compression with proper quench using a 258 crank with 4.0L rods. We have not gotten comfirmation on the exact specs of the pistons, but we have our fingers crossed.
   Many of us asked for Hyper pistons, but casting costs seem to have led KB to go with forgings. This makes some of us happy and some of us sad. I am sad if I decide to build a Jeep stroker for use in a DD, but, I'm happy if I decide the American needs a stroker as it will not be needed in the cold-cold of winter.
   If KB gets the pricing right on these pistons I plan on assembling a shortblock for use in something.
