IM BUILDING A 347 WITH FORGED KIETH BLACKS, HELLFIRE RING 4340 I BEAMS, 28 OZ BALANCE. STEEL MAIN GIRDLE

I HAVE TRICK FLOW TW HEADS AND R INTAKE,30# injectors and 65 mm TB

I THINK THIS MIGHT BE A SOLID BUILD, WITH MY POWERDYNE UNIT HUFFING 9#S

WHAT DO YOU THINK THIS WILL PUT OUT. WHAT SHOULD I LOOK FOR IN FUEL REQUIREMENTS,WHAT ARE THE OPINIONS ON THIS SET UP
 
I got a good girdle for the block. But that stock block is going to have to hold. Boost is kept moderate and fuel is kept at hand it can hold.

Keeping up with the 500 horse club Z06,Shelby, and Cobras,
 
my brother is stroked and blown with the factory block and he hasn't had a problem yet"knock on wood". it will hold together if u don't abuse it. he put out 465 at 6600rpm. thats without the supercharger. he has a powerdyne with only 6psi. trust me this thing is quick. yesterday was the first time i drove it and its nice. when he was n/a he didn't have any power til 3500 rpm. now with the supercharger he has power down low and its nice.
he has a main girdle from dss. and a valley girdle. that is alot of extra strength. but again if u go out and raise hell all the time it will break.

450rwhp should be EASILY attained, but I'd be VERY surprised if you didn't eclipse that easily. For fuel, as Joe said you'll need at a minimum 42's, but 55 or larger would be my suggestion. You will also need at a minimum a 255 high pressure intank and a high flow inline pump as well. It will need tuned too.

Believe what you want, but I'd be cringing everytime I was into the throttle if I had that combo, or the other listed running that kind of power due to the block. They are weak and due to the thin cast walls. After you get it together I'd start a fund for a better block IMO.

Amen!

If anyone thinks that they are going to be in the 450 RWHP range with a H/C/I 347 and 9 PSI, they should probably find another person to build their motor or tune their car. That combo should make an EASY 500 to the tires....

:SNSign: I already purchased the inline fuel pump. I have a 190 lph in tank now which will be there untill i add the blower. Aluminum Fuel rails to feed the beast. MESA BALANCING in miami should be doing the build. he is reputable I currently had my car tuned by WILLIE Diablo sport:mad: he does hell of a good job tuning he was the only one who was able to tune my old setup in a drivable state.

Do you think the 190 with the 30#ers will be enough for the 347?
When will the blower be safe to install on a fresh 347.
 
As stated a million times before, get a set of 42's and install that 255Lbs intank.. I'm in the same frame of mind with building a twin turbo set-up with a stock block. Think I'm going to have to reduce my block to scrap metal until someone drop 2 grand in my lap for a new block.
