Looking to upgrade a stock 5 speed V6 to around 300hp. I know gears will give it a good kick in the ass but Im looking for rwhp. Whats the best most cost effective hp for these motors with quality parts.

sorry h/c/i neither..best thing to do if you dont want to waste on a blower due to funds bolt ons will make your pony fun as hell..and you can get a bottle of zex 75 shot hp may not be in the 300hp but torque will be 350tq+ and torque is what wins races.

SuperSix has numbers on h/c/i, but its only for Stage 2, in their words:
"4.0 SOHC Mustang, automatic transmission, single exhaust, Stage 2+ cylinder heads, gained 25 peak RWHP and 19 ft lbs RWTQ with non peak gains of up to 50 RWHP and 80 ft lbs RWTQ with no tuning changes on a Mustang chassis dyno".
Now with tuning you'll see an increase, and they have Stage 3 heads, but either way you probably won't hit 300 HP with H/C/I, but it certainly will give the car a kick in the pants thats there all the time unlike NOS.
