Yeah, I agree. Skru the Patriot springs. I'll probably go back with a set of K-Motion. I know they work. Thanks for the suggestions. The isky tool room stuff is real pricey for a 6500 RPM engine with around .600 lift. That shouldn't be too hard to control.

6,500 in a sbc 383 (388ci) stroker is still asleep too.
Will run good though at 6,500 RPM's.

Thanks Brian, that's what I thought. This is the Impala engine and not the Vette. The Vette is going to be the RPM champ. On the Impala I need enough bottom end to get that 4350# pig rolling. It's only got 195cc heads but they are flowing 290/208. It's probably not impossible but it would be interesting to design an engine for a whole lot of bottom end torque and a bunch of high end horsepower but I'm sure it's not in the budget.
I'm building the Vette and the Impala engines at the same time and that's taking a toll on my wallet. All good stuff in both.

I don't think the OP's will fail that quickly. OTOH, I would never recommend to ignore that possibility.

Low end torque & High RPM power.
Has to be done with moderate Cubic inches to big CI, Intake tuning, & exhaust tuning, with carefully chosen camshaft.
Not sure any current cast EFI for a C4 fits the need though.
Definite no Big tube headers available for a C4 out of the box.
2 engine builds at the same time.
WOW.
Can get expensive Yes.
Got your PM.
That is bad news about Mahle.
Go Diamond or JE pistons.
Never used Diamonds but people have told me they are very best for some time now.

The good thing about Diamond is that they will make engineering changes for something like 6 bucks a piston. If you want a 12 cc dish instead of their stock 18 no problem. If you machinist got your bore a little oversized and you want a 4.035 bore piston......6 bucks extra. That's kinda hard to beat for the price.
