SBC HEADS & CAM UPGRADE
« on: February 13, 2019, 08:03:04 AM »
Planning on upgrade to street rod. Presently has 95 Chevy 350 from C-10 pickup, flat tappet hydraulic, stock except for aluminum dual plane intake with Qjet 1708228 with Cliffs HP kit and jet/rods, roadster headers, RV can(LSA 112, 214@.050, .442 valve lift, lobe intake center 107, lobe exhaust center 117)
HEI.
Looking to install Sportsman II or SR heads along with a roller cam retro kit with roller rockers. Lunati seems to offer several with LSA. Of 112 to 114 which I would expect to give low end torque. They show an operating range of 1500 to 5800 rpm.
This vehicle weighs 2700 lbs. with full gas tank, I

Good chance if your block is from '95 it already has roller provisions. I got a 350 out of an '87 3/4 ton pickup that originally came with a hydraulic tappet but all the roller machining had been done except the 3 bosses in the lifter valley. I had to drill and tap them to bolt the "spider" down. Lot cheaper than the "retro fit" roller lifters.

1987 and later blocks are already set-up for roller camshafts.  It has the provisions in the lifter area and the front should be drilled for the camshaft retaining plate as well.....Cliff
