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

273 rockers and a solid cam is my only way? Never had a solid engine before....maintenance and all , always had the roller engines ( carburated magnums )
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.
