What I got is a 77 plymouth arrow. Came with a 1.6 and automatic. Fully option high model weigh in around the 2100 mark. I took the 1.6 out and shoehorn a 360 from an 84 dodge van into it. I haven't finish it yet but it will be done someday. Anyway here some pics.
The old 1.6

The new 360

A picture of the whole thing before I pic it up from my friend.


Now some specs of the size of this thing.
overall length 170 inches
overall width is 69 inches
wheel base of 92 inches
yeah it small.

Compared to a geo metro the metro is taller, wider and but a geo metro is shorter.

 

Nice, can't wait to see it finsihed.

 

To answer your question, no it is not. This is however subjective as the term is ill defined for the most part. By most definitions to be classified a muscle car it would have to be from the mid-'60's to the early/mid-'70's, 2 door, RWD, high power V8 (usually big block, but not always as there are many potent small blocks),mid-size (smaller cars such as the Camaro, Mustang, Cuda, etc. are usually refered to as pony cars, but again that's just another example of varying definitions) and they would have been such straight off the showroom floor (this does not mean that they have to remain in stock condition though, they can be modified and still count). By other definitions though, yours will be once it's done. It all comes down to which definition you go by, some of which include new cars and others.

Here is a link to a good breakdown of what the majority defines as a muscle car and what is not: http://www.musclecarclub.com/musclec...finition.shtml

I cannot wait to see how that Arrow comes out, it will be more of a missile than an arrow.

 

Though it's not technically considered a muscle car by many's standards, it'll definitely be one cool little cruiser once finished. That 360 will definitely make it move, so make sure the chassis is stiffened up along the way (frame connectors & such) so you don't twist the car apart when you jump on it.

 

darn!
I ownd a Buck GS rag with a 400, 4 speed and posi that qualified, but it was doggish compared to the 396 Chehvelle's of the era.

Had a 62 300 rag 413, duel carb that would really get it on a kickdown.
A 69 Bonnie 421, tri power that was nothing but fast!
A (68 or 69?) Olds Starfire with a 425 auto, posi, that really had it's act together and would kick butt on Road Runners and Super Bee's.

In 1967 at age 17, I found a Dodge Coronet on a lot. No chrome side stips, and small hub caps on painted wheels. Not a cool thing back then. It had a bench seat (also not cool).
Looked like a stripped down cheapo version, BUT, it had a hurst shifter on the floor? Checked it out, and it was a 4 speed, and the clutch was really stiff. Looked under the back, and duel exhaust was tucked under the back with downturned pipes. And there were these thingy's by the springs (traction bars).
Popped the hood, and there was a 426 hemi under there.

SLEEPER!

I owned it all of 3 days until my Dad busted me, and back it went. I probably wouldn't be alive today had I got to keep that beast!

I've been fortunate to own some classic, that IMO wewe "Muscle Cars". ( Wish I still had them!)

 

Update on the motor. Got an eldebrock torker intake, holley 650 carb, lunati cam, and double roller timing setup. Gasket match the heads and ported the exhaust manfold. Got a posi unit for the rear end but can pick up a 8 3/4 rear for cheap.

 

As was pointed out muscle cars are high HP cars from an era in time.Alot of money to buy and own now adays. But a sleeper can be any car with lots of HP,a nice basic paint job and someone sitting in the drivers seat with a big grin on their face.
