I run a stock HS-LU in my a999/904 tranz with the voodoo roller cam

same stock HS-LU unit that was on the stock roller engine combo

works good in my daily driver,lets the 318 move out of it own way compaird to the LS-LU I had in the other 904 tranz

but i think its more like 1800-2200

you looking at aftermarket TC?

seems a little high for a stock 318 roller cam profile,more toward a 360 engine
