    Well I got the backbone of the engine in, big plus. I really want to avoid a girdle if possible. And if this wasn't going to be a reality I was going to sell everything. So step by step. Make for an awesome street engine anyway. I think 1000 rwhp at the tire is definitely doable.

    That crank could open the door for some more to be made, spin the 350 to 7500 like John says.

    I dont think I'd push it past 6500-6800. This is not an NA engine . It will make more power by turning up the boost and opening up the cylinders so the heads can flow. . The Flow numbers from Scotty on the CNC TA heads mirror this . Its just not necessary . This will be a street car with the ability to crack 1000 at the tire .

    For the people that PM'ed me , The crank is stock dimensions. It was the only way Moldex would do the job. I guess to not have to do a clean sheet design. I had one other manufacture that was interested but wanted 11k$ just for R&D.

    Keep us posted on the build, with pics:cool:
    Yeah, if your boosting it, no need for high rpm, the turbo will move the air.
    Probably no need for even 6000 rpm.

    Yeah a rich Arab in Canada, go figure. He had the other one made. I mentioned it a couple times Moldex Made the cranks. And a year turnaround and a stack of money 5 . Im sure they could make more.

    Do you by chance have a part number & would you be willing to share (even via DM if you'd rather) what it cost? If not, I totally understand but the part # would help. I assume if a few of us got together that the more they could make at once the price might come down. I'm probably a ways off from being able to swing the $ anyway & don't need it anytime soon but was going to send my crank out & would hold off if this is an option.

    The crank is on its way, will be here Thursday. I didn't see any part number on the bill that I remember. This isn't something they are planning on producing from what I understand . Was fill in work I believe. The deal was done through Scotty Brown. I'd talk to him about it. It was under 5k$ all said and done. I don't see that going down unless you got a bunch of guys.

    1000 at the tire. Should be enough to have the highest hp 350 Buick to this point. Unless the Rich Arab makes more. I'm not in a competition.
