That I'm not sure. Maybe it can but they are building this for boost. I did read the engine is more shallow, but I don't know if that's the overall dimensions or the block itself.

That's half the point of building a GM small block up. You can get rid of the truck redline. LT2 has a relatively short stroke, the piston speeds should support some pretty high revs. I think we'll see 7500rpm builds become common and the drag racers and track rats will probably go beyond that.

Just moving the Max RPM to 7050 with existing trash gears would be a major improvement to mid-range-go-fast.
7500 would be earth shattering in terms of improvement and that is w/o a new gear set...
do both and we'd be seeing a lot of crazy 1/4mi times

Sweet Mother of God. I hope this winds up being accurate.

Praying the trans tune will have similar results on the C8

I don’t understand how it stops pulling as it only drops 1700rpm and drops very close to peak torque? I’ve only driven a C8 on road course that’s vmax was top of 4th though it’s not like the LT2 is a peaky engine and believe the aero drag is greater in this car because of it’s exceptional cooling that comes with increased drag.

car doesn't need all the OD gears. I wonder if anyone has taken a fancy hewland box from c8r to put in in the street car
gear ratios are so much better. No fix for the tremec in sight 2 not 4 OD gears would be plenty!!

Yes, obviously! You wouldn't install a big inch build with a big camshaft and expect the stock ECM to "compensate". Now that you can use HP Tuners you can raise shift points, change torque tables, alter knock sensitivity and change timing to suit your exact build.

Right, but you can’t control the TCM yet to raise shift points is my understanding no?
