Headers. Why?

[1978 NYB]

Welcome Dave

Now compare the 72 Low compression motor to a 440 that some may build .. 500 HP range and the value of breathing really shows

Smaller differences on the LC motor and major differences on the Higher Compression motor with some Mods many do that are well within a lot of peoples range and are not a race engine.

Even if you wouldn't invest $1.5 to 2K more for the 500 HP build vs your LC motor rebuild (diff being heads, manifold, carb vs stock) you would most likely bump up the compression and have a MP electronic ignition even if you stay with stock rebuilt heads, intake and carb .. your HP would move up based on the compression alone and the differences would be more substantial than the 7.5 compression test engine.

Sorry it's hard to read but hopefully you can adjust screen size to magnify .. my spreadsheet was getting pretty crowded

10-20 TQ and HP jumps (more with more compression) vs 50 - 75 TQ and HP jumps

Here you go.....

This is based on perfect weather conditions, at sea level, and no traction problems...

Calculate ET and MPH from HP and Weight
Weight	HP

Your ET / MPH computed from your vehicle weight of 4500 pounds and HP of 500 is12.12 seconds and MPH of 111.54 MPH.

Wait a hold it. A ten second car can run 10.99 and it is still running tens.

It all doesn't matter, what Bryan is posting is the proof positive

 

[1978 NYB]

Even a 10.99 ET requires a **** load more than anything we are looking at here. Not to mention a transmission and tires and suspension that can handle that kind of performance.

 

[1978 NYB]

Not to mention the uni-body starts twisting and welds breaking....

Forget it......let's go back to "headers look pretty".

I'm good with that...

ok I'll take 12's on the street...

I agree 12's on the street is great!!!

The calculation is for perfect weather conditions, at sea level, with a bullet proof drivetrain, and great traction on a 1/4 mile flat surface.

I'd love to see that. Been to the NHRA event up in Brainerd, those top fuel cars are something else. I love it when you can feel the power as they pass.

Wasn't there a guy running a Fury bodied pro-mod, damn that was ages ago?

I would rather go to a ProMod Race over a NHRA National Event any day.

Not me..... I much rather see street cars running, they're more real

You haven't seen the 422 All Stars???? They are racing with the ProMods several times this year up and down the mid-Atlantic....

[polara71]

Is that what you call pro mod?

 

[1978 NYB]

The 422 All Stars are 10 second Nostalgia Super Stock cars......

 

[1978 NYB]

Is that what you call pro mod?

No.....

 

[1978 NYB]

ProMods run in the 5's at 250 mph.

No.....

Thank you...... those would do much like the F.A.S.T. cars

There is a couple of FAST events in the mid Atlantic too. I know at least one or two events at my local track......Cecil County Dragway.

 

[polara71]

They Co exist at the Mopar show in Englishtown

If I could I would. The national events have been what worked with my schedule and what I knew was happening. Move the mid Atlantic to the mid west and I'd be there!

 

[1978 NYB]

I usually make it to E-Town for at least one race every year and Atco once or twice.

 

[65Fury440]

I have a 440 source 528 shortblock on the stand right now. I'm going Indy EZ1 heads, and I don't know what cam yet. I am currently looking for a dana 60, and have subframe connector stock in the garage. I'll take the 10 second challenge, Oh yea, I already have headers, going up from 1 7/8 primaries to 2 "/

 

[polara71]

Atco is ten minutes from home
