Have a 88 formula 350 with the l98 and im wanting to add a little something for 2k. will be doing nitrous went turbo and sc on my 89 fox and it didnt go well. so Im thinking 150 shot, stealth ram intake and some long tubes with 5" dumps facing down and away from car. it is auto. What do u think.

 

5in dumps are waaaayyyyy to big, 3in MAX, 4 inch is only necessary for turbo builds, even at that point 3in will do most of the time. i would say 400-420 hp to the wheels

 

Sorry should have specified. the long tubes wont be 5" in size thats the length of the dumps thems selves.
