I was going to get the Edelbrock Victor jr. intake manifold for my 99 gt but I saw that mmr has options for porting. their claims are (Stage 1 + 15-20 HP,Stage 2 + 25-30 HP, Stage 3 + 35-40 HP). Has anyone went with any of these option before or does anyone think it is worth the money for a setup thats making around 600hp?
