So here we start....150$ 318 LA short block

no. Tons of small blocks with hydraulic cams shifting at 6+. I shifted my old 340 at 6k with a MP .474/280 cam hyd cam. Maybe take a gander at Isky cams, Crower cams, Crane cams, there are some nice choices. I'd browse and nose around. You might even venture and call Oregon Cam Grinders and tell them you want torque around 1800 rpm's but a shift between 5800-6000 rpms. Just nose around some... Cam is very important in a 318 when daily driving but wanting power up top. Especially in a E body with 3.23's. Your 4 speed will help a ton.

Yeah but you still need at least an anti pump lifter which requires adjustable rockers to run zero or a very tight lash, so why not go solid and get even more benefit? A standard hydraulic lifter will not hold up to sustained or frequent revs to and past 6K without issues.

Or to put it another way that cannot be argued with, "I" am not going to recommend it. "YALL" can run whatever the hell you want. lol
