Ive been looking at some videos with 347s having 500 plus hp. What combos would be needed?

 

A good h/c/i with a big shot of nitrous, a s/c or turbo. Shouldn't take much boost.I am sure that you can do it n/a though if you tried hard enough.

 

Its possible N/A. anythign is possible with enough money. ha. easiest way is to get a good h/c/i combo and stick a blower on it. my friend had trick flows with Gt40 intake with a vortec at 13 pounds making just under 5. with meth injections he goes way over

 

i got a pretty nice intake and cam. f303 cam and rpm performer intake. i just need some heads. i was thinkin about the afr185's

 

Step one: New Block...

I hope you plan on using a Iron Eagle block or a Boss Block or something of the sort. The stock configuration becomes very weak at the 500hp mark.

PM Portmaster, he has a 581hp N/A 347. Maybe he can give you some pointers on what you need to use. I believe he is using Trickflow heads and a carb setup.

 

Portmaster is gone from here, plus he never had proof that's what his made just what the desktop dyno said it should be.......he was using eddy heads too.

 

why is portmaster gone? just leave, or did he get kicked

 

with that set up you'll be lucky to hit 325-340 rwhp...what you need would be a well built 347 bottom end, a stock pluck might be at it's outer limits but with a well tune it could survive but to be safe I'd go aftermarket and get a solid roller designed up for the cam, some TFS 190CC FAC heads, and a victor jr intake with a 750 carb from Biggs performance or pro systems and some custom 1 3/4 lt's and have the valvetrain setup right and hold on, if that doesn't come close to your goal I'd be suprised

 

As a character would say..... a 500 HP capable N/A setup, that is not. That 347 needs to breath, and those specific components will not allow it to.

 

he was shown the door.
