Should be good for near 500rwhp. Not to mention the spool time would be very very short.

I think he meant shock shortblock.

A friend of mine has a 5.0 stroker KB mod motor built with cams, its by far one of the craziest cars I have driven. Its about 700 RWHP and built for a whole lot more boost. Those mod motors aren't the slug that alot of people make them out to be!

wow amazing Mach! props!

Angus66

The info is correct.

Race weight is typically ~ 3200 lbs w/driver.

The entire long-block is 100% stock & has never been apart for any reason.

The only thing non-stock inside the engine is the oil.

Thats what i thought you said . Your Full of it no 280-300rwhp car weighing 3200lbs is going to run low 11s on motor. That has to be some sort of record if so LOL .

Angus66

Who said my Mach had 280 - 300 (n/a) rwhp?

Is that a number just you pulled out of thin air or do think that's what a bolt-on Mach should make?

A lightwieght, bolt-on Mach with something like a 4.30 gear and the right tire should make due. Those cars really love and react well to those gears, even something like a 4.56. He probally is going somewhere in the 10.6-10.8 range on a 100-125 shot............ Correct me if I am wrong.

Take a look at some of the light wieght, bolt-on LS1's I believe there has been a few to hit 10's

Build #1

Well, my friend and I had his LT1 Camaro running 6.79's in the 1/8th @ 100mph with ported stock heads and it was N/A, with a 4.88 gear..........4 years ago. Of course we modified the stock intake with sheet metal. Thats a nice Mach though.

330rwhp? YOU DID! And times are believeable, while the MPH might be a bit high. But hey, anything is possible when you're driving a tin can with a ton of gear and a full drag race suspension right?

germeezy1

It doesn't take much to get a Mach 1 into the consistent mid to high 12 second range.

Angus66

Simply a typo when I replied to 2001z's post...

My Mach trapped 119 - 120 mph at Cecil Dragway, a track known for high mph no matter what the make or model car.

It trapped a more realistic 118 mph at Atco while running the same ET.

Tin can?

My Mach is far from a "Tin Can" in full race trim.

It sill has the complete factory interior (carpeting/door panels/console/interior panels/etc) minus the rear seat (replaced it with a delete kit) & passenger seat.

While this isn't my Mach 1, I would consider this Mach to be more like the "Tin Can" you're describing:





And since when is 4.30's or 4.56's a "Ton of Gear"????

2001z

iTrader: (32)

Lol a tin can is a car with hardly any interior which that car you posted has very little of . 4.30 or 4.56 gear is on the high end for a street car . Well if you didnt gut your car to that extent how did you seem to lose around 300 pounds ? I will admit when im wrong and your car sounds like it is legit. I should have asked how much suspension and gear you were running and which tire before i went on to claiming bs. Machs and cobras are the only fords you would catch me driving congrats on a healthy ride

Chris Gage

There is quite a few ways of stripping weight while leaving the appearence of full interior. Lightwieght carpeting, Lieghtwieght wheels, wiring, air duct, supports, lightwieght suspension, grinding metal, doing away with un-needed components, ect....

How much does your car weigh Angus? 3200 with driver kinda leaves a wide range on the table........... You could be 150 lbs or 350lbs, makes a big difference. I believe I have heard that the car sit at about the 3k mark give or take.

Mach's have alot of potienal, and for a Mach, 4.30 and 4.56 gearing is not all that bad. I know a few people running 5.xx gearing. Those cars really wake up on the track with gears like that. 3.55 gears do those cars no justice at all in n/a form.

Your weight reduction:

A/C Delete
No Passenger seat
Lightweight Battery
Lightweight driver seat
Self-Made Rear Seat Delete
Rear Mach 1 Sub Box removed
No front sway bar, jack, spare tire
Trunl Panels & Underhood liner removed
Front & rear bumper support brackets + foam removed
Stock radio/CD player replaced w/aftermarket gauges & panel
I'm not going to include the tubular K-member, coil overs, and other driveline lightening modifications as they serve more than just weight reduction.

Like I said, tin can.

I'm not doubting you or your numbers. As usual with the hardcore bolt-on guys, there is MORE than just bolt-ons, and I'm just pointing that out. And yes, 4.56 is considered a lot of gear, even the DOHC Ford crowd.

germeezy1

Without a double OD tranny like the T-56, running 456's in a Mach 1 or N/A Cobra is really agressive for a street car driven often on the street.

germeezy1

Also the TR3650 in the Mach 1's does not have the higher .67 5th gear that the 01 Cobra's have. They have the .62 overdrive which is even lower and is even worse for those steep gears on the highway.

Angus66

Agreed.

That's why I posted those pics.

I would disagree with that statement when applying it to a 4.6 liter DOHC.

4.10's or 4.30's are very well-suited for a daily-driven 4.6 4-valve, manual-trans Mach 1 - they should have come from Ford with 3.90's or 4.10's minimum IMHO.

I would say that 4.88's would be the high end for a street-driven N/A Mach or Cobra.

Keep in mind the 4.6 4 valve hasn't got a bunch of displacement & relies more heavily on (higher) rpm to get air in & out and make power.

Admitting that you might have been wrong - especially on the internet - is rare & pleasantly surprising.

Thanks.

I haven't done anything drastic (in my opinion of course) like grinding or cutting out metal, removing air ducts or wiring, removing sound-deadening material or even lightweight body components.

My Mach still has power windows, power locks, tilt/cruise, both air bags, ABS, power steering & (factory) disc brakes, etc.

Lightweight wheels/tires, lightweight suspension components, lightweight driver seat, no front sway bar, no jack/spare tire, lightweight battery, ~ 1/4 tank of gas, have been my main weight reducing items.

Just typical weight-reduction stuff that all adds-up.

Usually right at 3000 lbs without me in it, just as you have heard.

I did get it down to 3129 lbs once (with driver), but the fuel level was a little low for my liking.

I weigh ~ 200 - 205 lbs in "Race Trim" with helmet/fire jacket/shoes/shirt/pants. Not exactly a featherweight (I know a few drivers who are 145 - 150 lbs in "Race Trim"

Nice to see someone who has a little knowledge of these cars...

Exactly which of the listed items turned my car into a "Tin Can"???

Please elaborate...

The blue Mach I posted pictures of - no door panels/no carpeting/no interior panels/metal cut-out of the doors/no sound-deadening - is a "Tin Can".

Mine isn't even close.

Just out of curiosity, what do you call the Bolt-On LS1 cars that have ran high 10's but weight 2840 - 3090 lbs w/driver?

What weighs 300 lbs less than a "Tin Can"???

Wise choice.

I don't think there really was a need for you to point it out (I've always been up-front & honest about my mods & weight) but thanks anyway.

No it isn't.

Ever heard the phrase "Don't fear the gear"???

When 4.10's or 4.30's are considered a minimum gear to even bother installing, why would 4.56's be "a lot of gear"???

Since you obviously missed it, here's a news flash for you...

4.6L DOHC Bolt-On Ring & Pinion Rule of Thumb:

'96 - '98 Cobra: 4.56's minimum (4.30's if you rarely or never take it to the track) or 4.88's if you plan to visit the 1/4-mile regularly.

'99/'01 Cobra: 4.30's minimum, (4.10's if you rarely or never take it to the track) & 4.56's (or even 4.88's) if you plan to visit the 1/4-mile more than a few times a year.

'03/'04 Mach 1: 4.10's minimum if you rarely or never take it to the track, 4.30's if you plan to visit the 1/4-mile more than a few times a year & 4.56's if you plan to go regularly.

(The above of course assumes a 26" tall drag radial, DOT slick or full slick out back.)

3.55's, 3.73's & even 3.90's (and 4.10's in the case of the '96-98 Cobras) are considered not worth the expense and/or trouble for a bolt-on, N/A 4.6L DOHC's.

Any questions?

Angus66

You've got that backwards.

.62 is lower than .67 & results in reduced cruising rpm for highway driving...

The double OD has little to do with streetability when using 4.30 or 4.56 gears.

The steep 3.38 1st gear of the 3650 (vs 2.66 in the Cobra 6-speed) has more affect on street manners by far.

Sure... Why are you only picking up 4MPH on a 125 shot?
