that list just saved me lots of time
Very nice work on the demon! I am building a 5.7 with all forged intrenals studded mains and close chamber heads ported by SHARADON PERFORMANCE I am also using one of there 545 transmission out of truck with a stand alone controller and a TURBO at 15 to 18 pounds of boost! its either going in my dart sport or a 69 coronet rumble bee! Your build maybe swaying me to the dart sport. You ever thought about a power adder?
Esti de bonne job! (translation)....f#$king nice job...for reference only
Whatever he wants, lol!!
Are you running the power steer or air con ?

Kudos on the fabricated intake btw - Have you dynoed the engine?
What size and backspacing did you get for the wheels and what size/brand of tires are you running?

what do you have your rev limited set at????? You do know that after 6000 rpm the map sensor is removing timing??? just a heads up also did you run it with more initial timing on the dyno???? Did they play with the map at all or just pull it???? Steve
I'll chip in here because this is something I need to learn

- is the horizontal row of figures on the MAP chart RPM, or BAR? (see pic below)

It may also clear up Swifters question about retarding timing above 6k

You can probably run a couple degrees more timing than what I posted for you assuming you have an early truck engine and good gas. The chamber was 85 on the early 5.7 heads and the compression was a bit lower.
OK - fwiw and for those that want to know - the horizontal axis is manifold pressure measured in PSIa (Pounds per Square Inch Absolute sea level)

As Manifold pressure increases, the MAP sensor pulls the timing that was added initially for lower intake pressures found at cruise (Like a Vac advance but using Intake pressure)

As Swifter commented...I do wonder what happens when Manifold pressure reaches 11 PSIa ????? the MAP chart shows its taking timing out after pressure reaches this level.
