After much bickering I can have them made at $239.99 in the OEM 89mm bore. I will proceed with this asap.

Hi picto,i could provide technical drawing of the OEM if required
Hi,how is the kit going on如果其他人想谈论一起订购以使其物有所值,我会对 carrillo 的活塞/连杆组合感兴趣。我曾经看过一张单压缩环活塞的照片,我认为这很有趣。我对论坛很陌生,我已经开始在新的 2020 模型上进行全面构建。希望我们能把一些东西放在一起,造福所有人。
干杯,克里斯
I wanna buy that,ChadAll my pistons were JE std and over bore. The plus 3mm works fine, plenty of cylinder wall left. Carrillo rods work well of course. Did several of them.
I race a 390 here in Canada. Over the winter we built the motor with the fire ring, new piston, gaskets, valves, etc. Well, it just blew on me. The connecting rod bolts let go! Just as you describe. Every part inside the motor is toast……Raising this topics a bit. Superpacman13 can maybe comment on the progress with JE pistons what I at least have already pre-ordered from GreyArea store
What concerns the rod bolts- I am becoming increasingly worried about the fact that also these could be a potential risk for having a sudden complete engine destructing event to take place. Especially on engines used at the race track and subjected to high rpm most of the time. There seem to be a number of documented cases on 390 engine rod bolt failures and I know at least one case where relatively new engine got destroyed at the track because of a "rod failure" (that was all I heard after).
Superpacman13 as you commented having experience with 2 of these bolt failures alrady- do the bolts themselves seem to be the reason for the failure, or do you suspect some other element causing them to break?
While thinking one way to mitigate the risk of such rod bolt failure would also to replace the conrod with aftermarket one- I am questioning though, would that combo (JE piston, Carillo conrod) would throw the engine out of balance when aftermarket components are probably considerably lighter then OEM ones?
