I have a chance to get my hands on a 400 in good shape. Now, will a holley tbi fuel it? Or well I suppose a 454 one would since it fuels 454 cubes .
Jusst want to know if it would work?
Well that is

 

its been said that the holley or 454 TB will only fuel about 330 or so HP. something like that.

 

330 thats it?

Hmmm, looks like I'll have to go carb. I'm looking for well over 400 more towards 500+ HP. Anybody have a good rear I can have

 

it will support a lot more than that. it is all about tuning though. jprevost is running a 330hp crate motor that he has tuned to put out even more crank hp than it is rated at and he is still well within the limits of the holley tb. i would say you cna easily support up to 425-450crank hp with a holley or 454 as long as you tune the ecm in properly.

if you are lookign to go that far you may just wanna look into one of teh holley 4barrell tbi's. they have 700 and 900cfm bodies with 4 injectors. i am sure they can handle your goal numbers easily once they are tuned in.
