Any drawbacks to using 1985 LA block to build 408 stroker?

Originally I was planning to go the Magnum route since it already is setup for a roller, but maybe staying with a LA plant would be easier since I already have a LA block in the car.
I don't want to use the block I already have since the ears where the motor mounts attach are not great.
I’ll assume that the current engines motor mounts are rotted, chipped or damaged in some way that gives you worry. Because the ‘85 LA 360 is the same configuration.

Otherwise, it should be fine for use. As said above, sonic check the block first and then order pistons with the kit. Just don’t assume the block can go .030 or .040 over bored. There really should be no problem.

FWIW, a good solid cam will work as well as a street roller cam. It’ll save you some bucks. If your heart is set on a roller, then go for it.
