Your say he needs 350 hp and is 105 hp away from whats needed cause the stock hp is 245 hp. The only problem I see with this is there are two different ratings going on here gross and net. The 360 probably makes closer to 300 gross hp so he's only about 50 hp off his goal.
I'd be looking for better cylinder heads and a touch more camshaft than this. The headers? Well we tested TTI's vs the cheapo Summit headers on a 600 HP small block and found about one horsepower difference average from 3,000-6,000 rpm. After 6,000 rpm the TTI headers were better.
