    Engine mounts

    I have a 1990 gmc sierra and want to drop a ls1 from a camaro in it. The truck has a 350 5.7 in it, can I use the trucks original motor mounts for the ls1?

    You will need aftermarket mounts. Summit and Jeg's both have listings for a mount that adapts from the earlier generation setup to LS1, if I recall correctly.
