Ok, I'm building up a 400 small block for my 88 bird. I had a pretty good setup in mind and was gonna go to Summit soon and start putting it together. I was looking at around 400Hp and 450+Torque. Well, my brother let out today that he is building a 400 too for the fourth gen bird he's buying. He has all his parts already and ran the setup on desktop dyno, He says he has 600+Hp and 700+Torque. He refused to tell me what he's putting in. With sibling rivalry what it is, I have to have the faster car. I need some ideas on a setup that will rival his. This excludes nitrous or any forced induction. Any ideas will help at this point. Thank you.

 

I'm also in the process of building up a 400 and all i can say is that you'll never make 600 hp without some kind of power adder and still have a somewhat streetable engine! My engines got a comp xr274r solid roller cam, Brodix cnc'd track 1's, a holley Stealth ram intake, and 10.2:1 compression. It should make around 450 hp and 500 lb of torque. I can almost guarentee you that your bro is using some kind of forced induction! But if you want to use a blower I saw a 406 with 8.5:1 compression, a huge solid roller cam, afr 220 heads, a mini ram intake, and an intercooled ati supercharger with 12 lbs of boos that made 750 hp and 700 lbs of torque! that should be able to pull!

 

I think you might be right. He does bull**** alot sometimes. Either he padded his numbers or has some kind of adder. I need to finalize my setup and start gertting my parts together. Do you have any overheating probs?

 

Oops, my bad I thought you said you had it running. Never mind on the overheating.

 

make sure with all this power that you can put it to the ground!

good luck with your engine!
