I can't locate my shop manual and was wondering what the factory spark plug gap should be for a 71 LS5 454.  I think it should be .35 but need to verify.

Thanks

Tom, ya left off the zero, but essentially you are correct. The gap is 0.035.

Thanks Dave, you're right .35 would be one hell of a gap!
