Here it is guys, my friend has a '70-'71 javelin with a 360. Not sure on any mods, but if it was stock, who would win?

I have a '91 gta with a 305tpi. Headers with flowmaster muffler,no cats, comp cam, 3:42 gears, ported plenum, msd 8.5 wires, trans-go shift kit and afpr.

Best time on my g-tech comp is 14.3.

WHO WOULD WIN?

jocww

he would easily

If you are runing mid to low 14's I would think you could beat him if he is completley bone stock. It wouldn't take much for that javelin to really scream tho.

Bit of advice, Don't bet against the Javelin. Even bone stock they will be quicker then the 305 GTA.

There seems to be all sorts of conflicting information about what engines were available in the 70-71 Javelins depending on whether a base model, SST, or AMX. The 360s that were available ranged from 175 to 290 hp (not sure if those numbers are net or gross). Not terribly impressive, but these were also relatively light cars.

Anyway, the best answer I can give is "it depends".

I'm not necessarilly betting against the javelin.However, his GTA is not stock,its supposed to be a mid to low 14 second car. That would be enough to possibly upset a bone stock javelin

factory specs for old muscle cars are under a lot of the time my dad dyno his 1969 ss camaro stock 350 300hp and 380ft.lbs and got 335hp and 405ft.lbs with 30,000 miles on it bone stock

The AMC would. I have almost your combo man. My dad is a hugggge AMC nut. He has a 74 AMX and a 68 Javelin. Man they tear it up. Plus the 74 runs 11's!!! Beware of the AMC POWER.

Let's not get carried away. AMC had several 360s - some were dogs, and some were not. The 2 barrel 360, for example, could barely muster enough torque to pull the skin off a grape, let alone outrun any third gen 305, be it an LG4, LB9, or whatever.. Just because it had a 360 didn't automatically make it fast.

Back in the day, I had a '74 Camaro with the 145 hp 350 that would lay a spanking on my friend's 360-powered '74 Javelin on a regular basis - it actually became boring after a while.

You need to do an apples-to-apples comparison - without knowing a little more about the particular 360 in this particular Javelin, it's all just meaningless speculation.

Never meant it like that. It is like any motor, if you build it right it will run great and fast.
I know because of all the AMC's my pops has had that they are a great setup waiting for some good parts.
AMX wise, well thats another story, been there done that. R4B intakes with factory numbers on the intakes, and so on.

Just a thought on this subject, would you keep a v-6 or a 350 v-8
3rd gen car for the next Thirty Years if you had a choice?????
Now if someone kept a 70-71 AMC Javelin for that time, do you think it would be a slow car????

My bet it would be a very fast old car.

TMX

Possibly....but people keep cars for a number of different reasons. Oddball cars like the Javelin seem to have more of a hardcore cult following compared to more mainstream rides like ours, and the reasons to hold onto one could arguably be more numerous (relative rarity, uniqueness of design, etc...). Granted, "fast" is a strong motivator to us, but different people are motivated by different things.

TMX

This is true. When my friend with the Javelin eventually got around to building his 360, word is it was pretty formidible (I had moved by then and wasn't around to see it first hand).

Anyway, the OP was asking about a stock Javelin/360, hence my "devil's advocate" stance on the subject.

You'd take him. Best time for a stock Jav would have been about 14.8 or so. I put a 360 from a 74 car into my 79 Spirit GT, and would run 14.5. Little lighter car, but crappy gears.

Not even a good race. I absolutely cleaned him. He got a jump on me and I caught him and blew right past him!

He actually had a '70 amx with a 390.

I used to own, build, and race a 71 sst that I bought new in 71 when I returned from Viet Nam. This particular Jav. was a demonstrator that I bought for 4,090 bucks W/8,000mi on it.
The manual said to burn reg. gas, but after 13,000 more miles, I burned a couple of valves in the 360ci and after I removed the heads to replace them I found these huge intake and exaust valves to the tune of 2.02in and 1.68ex. Turns out I had a 70 model 360 W/10:1 comp. in my 71 Jav.!!! It came with 2:87:1 limited posi, wimpy Autolite carb, and some kind of fomoco dist.
I drove the hell out of that car for 89,000mi in two years! and
I changed everything on it but the heads, block and pistons. Even with the piece of crap Borg Warner cast iron auto tranny, I beat the hell out of everything! at least once or twice!
I ended up buying a 68 AMX W/343ci that W/headders and a holley change ran as good as the Jav! The curb wt. of the Jav. was 3310 and the Amx was 3020. The biggest difference in the 360ci engines was the dog leg exaust ports on the heads. The HP. rating for the 4 barrel 70 was 280 net. not gross. Before I changed the rear gears to 3:54's It would do 100mph in second gear and I passed up 140mph several times after I changed the cam W/6,000 rpm Crower Hyd. The Doug Thorley comp. tuned headders made the biggest diff. of anything I did to the engine
In 71 the 360's comp. ratio dropped to 8:5:1 and the hp. sucked
Even the 401ci couldn't keep up with my 360. Anything you want to know about the 360, I can tell you!

Sounds like a dogged out 390!
