Hey everyone. New guy here. I have a 71 mach 1 that I would like to build a 408C stroker for. I have 4V closed chamber heads. I hate to be a copy cat but if ain't broke don't fix it. That being said, I'm curious if anyone has a setup that is totally streetable making in the 500's hp/tq, roller cammed with stock 4V heads (just mean cast iron not aftermarket as I figure they'll need to be worked some) that they can offer up. I've been told these power figures can easily be reached and be streetable but alas those that have said so have no actual setup (ie. specific cam, intake, carb etc.) to speak of. I know this is a tall order but I'm looking for someone with proven results rather than just trusting something my local speed shop says will work. Hope I'm not asking too much. Thanks in advance for the help.

 

www.dodgestang.com he is running a cleve stroker iirc somewhere around that level with 4v heads

he will probably be along his user id here is Dodgestang

 

I assume you mean 500 flywheel.

Shouldn't be too hard

I hate you, Nick. I hate you so very much.

(as a side note, that's one mean Marauder)

 

He blew the motor up last month. Overboosted it.

 

Sadface

 

That video perfectly demonstrates why you need front disc brakes.

dodgestang I may have to borrow some of your specs for my (one day) stroked 351C.

 

Two things to think about.

1. You need to really run the numbers on your pistons, rods, stroke, and combustion chamber so that you are not going to have a really high compression ratio. For street gas, 10:1 with iron heads is about all you want.

2. 500hp alone is not a killer, but when you achieve that with 500ft*lbs of torque, you are going to need beefy parts. Start thinking about performance tranny, upgraded rearend, highend clutch or torque converter, suspension, etc. Torque kills parts .

It is doable because that is what I am doing with a 383W. Just watch your CR and get good parts. 500ft*lbs is very streetable, but you will have some quirks and will probably break most of your stock driveline along the way.

 

not that urban has ever broken any parts........

 

Exactly why I am passing on the advice/warning .
