Intercooled or non, the non injectors will support just about that amount, but thats with more turbo, and like Bubba said you will need a pretty good trans to put down 325 on the dyno.

a guy could have 450hp and with a week trans never see 300 on the dyno.

S300g s362 is what most folks will tell you. I run a he351cw and based on my 1/4mile speed im close to 320hp

you can make well over 500hp with 5x12's no need for 14's a stocker off a 2nd gen can get you to 350 but an he351 or s300 variant will be a better choice. tc and vb are a must before you start making power. and like stated above non IC injectors are a fuzz bigger and built right stock stick will/should get you in the rehlm of 350hp.

Really?!

There's a LOT of folks who'd be very interested in that recipe (myself included). Care to share?

air man, let her breathe. this is on my 2nd gen not my VE if that is the basis of your argument. clean power is where its at. its much easier to get to big #'s with gobbs of fuel but why? 5x14's are dirty on the street, usable but dirty. my 12's can be to smokey -for me- at times. if you can make 350hp on stockers which are 5x.9's how could there be much argument over 5x12's making over 500? they move PLENTY of fuel for almost all DD situations. just because a truck vomits large amounts of soot into the atmosphere doesnt mean it is tuned properly or has anywhere close to the right mixture of aftermarket items on it to make it efficient.

I thought the OP was talking about a VE.
