Nitrous plumbing A1A...??..

Simply put I have a very addictive personality... That's why I don't do drugs or drink alcohol... "I used to do a little but a little wouldn't do it and a little got more and more" guns n roses....lol...
I'm going to order the 70011 Edelbrock cheater plates and I believe they come with 50 75 and 100 Jets. If I'm not mistaken they are square.. when I talked to Mike thermos she talked about the nitrous Jets being about .004 or so bigger...
My concern is being 2 or 4° retarded for 3/4 of my run and only 1/4 of my run using the nitrous. it would seem to me that I would lose power for three-quarters of the time and barely make it up on the 1/4 time I'm using it?..

2 deg retard NA from your best setting won't make much difference in power, (5>8hp?), have you tried it to see the difference, unless of course your already around 30 total deg because of your combo/fuel etc, which I doubt. On my iron headed 10:1 340 motor being back 2 deg (34deg) which was the most I came back made no difference for NA runs which was 90% of the time, ET/mph was the same, but that was my set up not yours.
