roller cams for la 360 /questions

If you havent purchased anything there are options. The lifter bores on magnums are longer in length. If it is a true LA block and you are set on going with a roller set-up I would highly recommend Hughes "Morrel" roller lifters HUG #5321. I put them in my 408 with a Comp Cam hyd roller and the work great. They also moved the oil band on these to accommodate the shorter lifter bores in the LA blocks and allow for pushrod oiling.
