I recently got a new bow and decided tostart shootingBlazer Vanes and a 4" wrap on my Beman ICS 400's. Will the same brand, size, and length arrow with standard 4" vanes and no wrap shoot similar to my new arrows??

Yes, IMO: I have been total that 4" vanes weigh approx. 24 grains vs. Blazers at 15 grains. = a 9 grain difference. I think wraps are 6-7 grains. so the 2-3 grain difference is so small that it really won't effect flight or performance.

i shoot 4" vanes...put on blazers and was shooting groups about 3" low and 5" to the right....i don't think it will be exact IMO...but it won't be way off

I went from 4" vanes to the BLAZERS, and I am shooting flatter
