69-70 Mach 1

General Chat

Q:

Well, come the end of october, i'll finally be in a position to get my dream car (flame away), and i was thinking.... i can get a great example, no rust, 351, leather, blah blah blah for $15-18,000. the problem is, would it lose value if i swapped the motor? or would it be alright if i kept the motor and tranny with the matching numbers, and re-installed them if i ever sold the car? would i get a better score at a car show with the original motor, or with say, a built 428cj? I dont want to spend upwards of $15,000 on a car, just to have it lose value if i make it faster.
(im keeping the zx as my daily driver)

It will "Most Likely" loose value at auction with non-matching numbers.
Build the 428, swap it in and keep the original 351 hermetically sealed and stored away in case you want to sell it again.

A:

Those cars always lose money if you change anything. They are worth the most if they are 100% original. It will go down a lot in value if you change the engine. If you keep the original engine and trans with it, it will not go down as much. The fact that you even put another engine in it at any time makes it worth less to most collectors.

Mustangs have nearly dropped off of my liked cars list. The only reason why the barely stay on is because some have "Shelby" on the side, and the 5.0 was real. They are just pretty scrap metal in my eyes.

If it looks anything like the one in justinhenry's picture, you should be put in prison if you even DRIVE it, much less change anything. If it's not show-car quality (which it seems like it should be at $15K), or has ALREADY been modded away from stock (interior/drivetrain/etc.), go for the swap. But yeah, keep the original stuff if you ever sell it.
For that $$, why don't you just snag somebody's unfinished whatever project (like a fiberglass Deuce) and drop yer bad boy CJ in that?

my boss whos restoring my z with me has a 69 mach one that needs a total of 10 hours of work to get it 100% streetable but since the second my z's been sharing the garage with it he hasnt touched it, not only that he's put in hundreds of hours of rust work, wiring, shocks, brakes and the works on the z...i always ask why he doesnt finish his own car first but he never has a answer for me...you would wonder why a guy who has $12,000 in parts and hundreds of hours into the car would wanna finish it off..personally i think he just likes the z that much more lol

I just got back from the vintage races at Mid-Ohio race car course where my car was in the Concourse D' Elegance, along with many other nice cars, and a couple of -F I N E- Boss 302 Mustangs. I commented to my son, that I would sell my Z in a heartbeat for the yellow 70 Boss.
"Have fun with a car that weighs a TON and can't turn... ;)"
It's funny that should say that because part of the weekend festivities at the vintage races included the 40th anniversary of the SCCA Trans Am series. There was one really hot, high winding 240Z, several Corvettes, a coupla Jags, alot of Camaros, and several Boss Mustangs that chewed the feild up and lapped the Z.....evidently they can turn also.
A:

Look for one that's already not original- then you have nothing to lose.

thanks for all the input guys. If i could find one in my price range with the original CJ, we'd be in buisness, but they are nearly double the price of the standard Mach 1. I'm not worried so much about resale as i am about show judging, and even then, im worried more about what i want and like. So i'm thinking i may just say damn the critics and swap in my CJ, and leave the 351 sealed up just in case i ever decide to sell it.

there's a '69 fastback (not Mach 1) two houses down from me that I attempted to buy form the old lady who owns it. She's had it since it came off the assembly line and it only has 67,000 miles on the clock. I almost got her to sell it to me for $6k, but she said there was too much sentimental value. I would have pursued it more but I couldn't up the price because the Z was taking up all of my money.
and yeah, I think those cars are sexy

damn. is that the car? ONLY 6k? how would you sleep at night?
'82 turbo zx
A:

no that's not the car, her's doesn't have the hood scoop, but it has the chin spoiler and it's pearl white, the paint and body is just about perfect though. As I said, my funds are very limited, I'm only 17 and the Z takes quite most of my money, but man would I love to have that car.

the z driver that got lapped obvioulsy wasnt driving the car hard. a well prepared z car will eat up those 2 ton muscle cars on any track!
A:

The Z driver was driving plenty hard but was out horsepowered by about 200-300 horsies by fully race prepared first gen Camaros, and Mustangs that weighed no where near 4000 lbs.
Never seen the old Trans-Am series cars run huh?.......cuz NO Z within the class rules could keep up with those boys.
A:

Are you kidding? If a Z was racing in a "RACE" with a race prepped Mustang, Crapmaro, or what have you the Z wouldn't need to be built with equal HP. Torque is what makes these cars, and turns are where they own. If you play straight line then you shouldn't be driving a Z, but if you like those turns and curves....
1972 240z w/L28, tokico shocks and springs, and a 5 speed waiting. Also running high performance ultra mega blinker fluid, that's at least an extra 50hp to the wheels.
1987 Toyota Supra Turbo 5-speed. Belongs to me until my friend get's back from Iraq.
A:

A big block V8 still produces more torque than any stock Z does.
That doesn't change that I'd still put my money on a Z over a Camaro or Mustang anyday. American Muscle is not my thing.

yes i have watched and also raced a few early trans am series cars (i still own one of them). the minimum weight for the 1970 race year was 3200 lbs less driver. they were NOT light cars as one would think.
the road racing courses are better suited for superior handling and not so much super high horsepower as the avg lap mph was around 90-93 mph. a race prepped 330+ hp 1970 240z would eat those cars up on those road courses (bob sharp racing for example in 1970) and by looking at the lap times back then they did if you research the records comparing the classes at the same tracks.
if i had a choice of having 200 more horespower on a road course or 1000 lbs lighter car through the turns....no 2nd thought there

A:

A buddy of mine had one. That thing in stock form was a death trap. It had loads of power but no handling. Taking a fast turn in one would result in huge body roll and the power steering was as numb as any 1970 American car. Styling was also a miss since it was in the time of "bigger is better" at Ford and all their smaller cars gained a lot of weight and size.
I'd be fun to have one, but only if you really loved it. As far as "Value", any one you can afford is not a collectable so "value" should not be a concern. Just drop in the engine of choice and have fun (IMHO).
