12 Second N/A Slant 6?
Just got off the phone W/Garu @ RAU.
Very nice guy to talk to.
They will modify the rockers & supply a smaller diameter SS shaft for a complete assembly for about $340. $300 W/the customer's core.
For the advantages of 20% better lift ratio, this is money well spent I think.
Thats 20% more lift, .450" lift W/stock RA will be .540" W/1.6 RAR & the valves will be opening faster for better cylinder fill.
Now, how to get the CR down under 11:1 & still maintain quench.
