Dream 400?
I'm building my baby into the mud truck she deserves to be, and have decided to go the 400 route. Right now its a 400, headers, intake and 4 barrel holley. I've sent an email to tmeyer about a stroker and this leads to my question. While Im sure he wont steer me wrong, heres my goals for the engine. I want the truck to have plenty of torque to turn 33's to start off with, using 4.10 gears. It needs to be able to pull away from a few imports in the sat. red light drags. It needs to sound good, have that lope to it. I know the sound thing is childish, but seeing as how Im not racing, and its just my fun truck, Ill sacrifice a lil bottom end for that gnarly lope I love. So what options should I be asking for on the stroker? What heads, intake, cam, and carb? Im using small tube headers, Ill check what brand when I get home on leave in 3 weeks. I want the tq to move the truck with authority and make it fun to drive, but definetly want it to have that nasty sounding lope. Thanks guys and Semper Fi

i wanted the same thing...i got a custom ground hydraulic roller. the way i decided to get the duration was based on the stroke, rod length, pistons speed and intended max rpm. ironicly this 219/222 is just about the max i think i would put in a truck that is going to run on the street because if you are running vacuum secondaries with some carbs 220deg at .050 is about max. without adding a ton of duration but still wanting some lope to the idle i got the cam with a 108 lsa(thumper cams are on a 107 with alot more exhaust duration). this may be a tad tight for a pickup with a desired power band from idle-5500 but still it should work fine. the lift will be based on flow numbers with the heads and intake flowed together, checking for reversion and other obstacles. after you flow the heads and intake call someone with them and have a custom ground cam made with you application.
as for heads and intake, if you are going with tim meyer, i would get CHi 2v's and an edelbrock intake.

Ok what happens if you throw that extra exhaust duration in to get the thumper effect? I know most long duration cams work well for high rpm engines, but no so great for tq based truck motors. How does increasing just the exahust effect the engine?

i'm not positive but...i think it will lower the cylinder pressure and hurt low and mid range torque and get worse milage because its less efficient because of letting unburnt fuel out of the exhaust... it's good for nitrous applications because the amount of exhaust is increased by like 50% and it needs to get that gas out of the chamber but they are ground on a 112-114 lsa and the exhaust is opened earlier.

Let me get this straight! You want a heavy truck with lots of frontal area, the aerodynamic coefficient of a brick, with HEAVY, large tires to be able to outrun a 2500 pound, short and small frontal area car with a good aerodynamic coefficient and light tires powered by a souped up four cylinder. Is this correct?
If this is correct, a 400 is not going to get the job done. I think you need to be looking for an engine made by Pratt & Whitney.

maybe lowering the brick to the ground, getting small tires, low gears but still woudnt do.......it would be fun to watch though......

The stroker is as money allows thing. Or do you mean the stroker 400? That is the plan right now, 434 stroker. And I'm asking the to beat the car in the 1/4, I'm talking about out acclerating a 3000 pd half built body kitted tuner 300 or 400 yds to the next redlight. Not to much to ask is it?

it can be done with a 400, my truck with the 38's can beat most ricer cars and if i put my old 31's on it i can keep up with my buddys stock 4.6 mustang

I could always use this.............its only 2000 shaft hp, but it do pretty good I think. And that is me in the pic, if your wondering. This is what i do everyday for a living is build these engines.

Okay so since the original poster is saying he "wants to pull away from a FEW imports" in the Sat night stoplight Grand Prix, then even turning those four huge tire flywheels this would be possible.
That means that if this 400 is REALLY built it will take on a Celica successfully. I would NOT, however, recommend taking on one of those Honda Civics with an Acura V6 bolted in.
I know that the mildly modified 400 in my 78 F150 short bed 4X4 with 33's wouldn't have a chance. In fact, I'm not sure I could do much with one of the local kids and their Honda Civic. The truck has good torque. I've even pulled my tractor out of a ditch with it. If I were to bolt on the L78 15's that came on the truck originally that would be a different story.
