About 20lb it say for the kit. So under 10kg. Pickup 3 for us all and you'll still be under weight. Just take cabin luggage for all your personal stuff.

Excellent, sorted then, thanks!

TL, the low profile sump is a must for every GM install in a Harrison. We have done a few C6 sump conversions on Harrisons over the years. Depending on the sump you have, you will gain somewhere between 35 - 45mm in height from memory.

Surprised the stock GM sumps fit in the classic revivials height wise. To do that you would need to run the drivetrain around 40mm higher than what we do in PACE 427. The slim line C6 sump is level with the bottom of our chassis (which is the very bottom of our car, nothing hangs down lower than the chassis, not even the exhaust). Technically the bottom is 8mm lower than this as this accounts for fasteners, shear plates etc.

On my LS1 setup the bellhousing on a t56 is approx 12mm lower than a C6 sump.

I've found this too with mine. The current plan is to mill the bottom edge of the bell housing flush with the sump.

I'll post some before and after pics.

I had the Camaro sump on my CR before and it was the lowest point in the car. Switching to the C6 pan gained about an inch of ground clearance. Milling the bell housing will gain a little more again.
