For the 408 your gonna need at least a 750-850 cfm blow through carb.The carb has to be modified with solid floats,rejetted,boosters,mill the choke horn(i have one for sale with a pump).You will need a boost references regulator with a 1:1 ratio and pump that will supply about 7-8 psi + 1 lb per pound of boost.My last pump I had was rated at 900 HP, would supply 25-36 psi and flow 310 gph.I used 1/2 line to the carb and and a -8 return to the tank.

Great info guys! I will get rid of the rear bars and see what to replace them with. Any recommendations? Also the auto is going to be out for a t56. The body of the car is straight and rust free that's why I decided to get it and build it. The rear already has air shocks so I guess I'll take them out. Any brand you guys recommend? On my old fox I had strange adjustable but for these type of cars from my understanding are not good. Cage will be added and subrames I want this car to get into the nines threw a 6 speed. Nothing like banging threw those gears lol

Oh also fuel system? I know stock pump will not cut it. What would work for this? Unless I have to go with like a A1000 system? That's around 2k for that or would it be over kill

A1000 is pefect for a blow though set up. I have $1800 in my carb and pump, make you a gread deal

Take a look at Caltracs for the rear suspension..They can also hook you up with leaf springs and matching shocks to make your car hook up at the strip...A 600+ hp engine that will be reliable will not be cheap..Are you set on using a blower?...A 408 based engine can do 500+hp without too much trouble without a blower..You could then add a small shot of nitrous to get you up and over the 600 hp mark..

I've been thinking of the idea of nitrous. but for me it's not consistent enough. Then the hassle of refilling the bottle kinda sucks. I know it's going to be expensive from my count I'm like 5-6k just for the short block. then the heads another 2300 ect.. I want to build it right the first time and not go back.

there was a thread a few days ago about a guy getting a 100lb tank of nawz for like 140$.

I am certain that well over 600 hp can be made with a well equipped 408 (without any need for power adders at all), for a lot less money and effort than the blower motor is going to need.

Not trying to talk you out of anything, but I thought I might mention it.

gearbanger

Yeah I'm looking up more things and a high cr with a small shot may be better. That blower money can be used for a fuel system. What I'm for sure of is getting a 408 stroker. I was quoted 2900 for a short block that will handle what I want to throw at it.

It sounds like you have a decent budget and are willing to buy some very top shelf parts for the motor..For the power level you want out of the engine you need to work closely with an engine builder who has experience with building such a combo.....I would recommend posting up your questions over here..http://sbftech.com/index.php The owner of the site runs this place and could build you a killer combo..http://www.fordstrokers.com/
