My carb'd 289 runs like a champ. I dont know why anyone would say a carb'd motor sucks..thats half the fun of having a 40 year old car..to each his own I guess.

Its the same principle. If I'd had the 1) time, 2) money, and 3) tools and 4) knowledge.... then I would have loved to put a modular in my 65.

That really is a testiment to a person's mechanical aptitude.

im calling bs on this there is no way that a vette weighs that little, they came stock over 3400 lbs, now maybe u meant 3200, but still its a fast car.
ih8chevy-
I find it interesting that you think you know more about this car than I do. I helped him pick up the car as a basket case, I watched him through just about every single step of the frame off restoration and I helped when he needed an extra set of hands. You have no idea of the modifications that he made to this car other than the running gear, motor and transmission that I vaguely mentioned in my original post. Unless you have all the facts, it might be to your benefit to keep your BS flag in your pocket where it belongs.

I just verified the weight with the owner and he said “It was 2,580 with me in it and the hard top on when I weighed it.†Now, take away about 200 pounds for the driver and 50 pounds (just a guess, I really don’t know for sure) for the hard top (which he doesn’t have on anymore) and add about 100 pounds (another guess) for the supercharger which wasn’t on at the time of weighing and you end up with about 2,430 pounds.

There *is* a “way that a vette weighs that little†and I did *not* mean “3200â€. In retrospect, I probably should have verified the weight before I made my original post, but I think the +/- in my post just about covers it. 2,430 pounds is much closer to 2,200 pounds than 3,200 pounds.

By-the-way, a stock 1962 Corvette curb weight was less than 3,100 pounds, possibly much less depending on which options it had.

Hello 67Sally,

Would I be out of line in mentioning that the Star Wars storm trooper on your posts kind of distracts me?

I am not saying I want you to take it off or complaining about it, just making an observation. I have to position my browser window carefully to avoid distraction!!

So when exactly are all of you guys who think the 4.6 is so completely awesome going to drop one in YOUR car? When are yougoing to spend $15k to put an engine in that is still relatively stock? Sorry but 390hp that the 03-04 Cobraengine has can be VERY EASILY duplicted. As for mileage, well the 4.6 isnt all that great on gas, especially not the Cobra. reliable? Well the engine might run and not make noise but if you didnt do som really fine engineering when you put it in there, you will have problems EVERYWHERE else in the car..

Come on, if you like the mod so much, pony up and put it in your classic.

the 62 vettes are very light. Not much car there at all, glass body, steel space frame. Also the mods needed to drop an LS1 into an older car are more to the engine than the car. Additionally the LS1 makes more power and gets better mileage with better driveavility than the 4.6 does. Throw the LS2 or LQ4 in the mix and even the Cobra engine pales in comparison. A stock LQ4 makes around 430hp NA.. To put a 4.6 in any Mustang built before 74 requires a complete rebuild on the front suspension, a huge upgrade to the fuel system, and someplace to put the ECM and related wiring. What do you have after you have done all of that work? A little bit of mileage increase over a well tuned 289, and about the same power as a mild 351. yay.

Just because it has overhead cams doesnt mean its a great engine or forward thinking. Pontiac had an overhead cam engine installed in cars back in the 60s. Buick had an all aluminum V8 in the 60s and it was still put in Rovers untill recently. OHC not really better, its just different. You want better? figure out a way to get rid of connecting rods, heavy cranks, and camshafts entirely. Less mass and recip weight means more power.

Sure if you want to be different or have a challenge, then you better have deep pockets. Sorry but I dont lust after any of the new Mustangs, simply because I have much cheaper easier to work on cars that get better mileage and suck the headlights out of the 4.6Ls. They are unimpressive to anyone who wants serious power on the cheap. All the kids who hang out with ricers in school just love em, but then you head over to the street strip section of this forum and you find the 4.6 guys talking about if they can beat a civic or an S2000..

So when are you 4.6 fans gonna chop up that old car you have and get down to it? Hurry up now before you realize its not a reasonalby feaseable swap..

Just to put my posts in perspective concerning the FI issue, I think that your car is b*t*h*n, and I would be proud to drive it. That is one smooth looking engine compartment and car as a whole is very, verry nice.

There are usually exceptions to my rules and opinions, if you have read my posts in this thread, you know I am a fan of carbed classic cars, but to look at your car is enough to make me want to reconsider my position.

Excellent execution!!

Yea, I was thinking of putting a mazda rotary engine in a classic mustang, to get rid of the recip weight!

Just kidding, Actually,on this subjectwe share some common ground. Iam a huge fan ofAmerican pushrod engines, I despise the idea of American engines emulating European and Asian designs when the central cam design has served us so well, in the past, and in the present.

Ithink that the OHC motors have certainlynot "re-invented the wheel", they have just made the wheel more complicated and expensive. There are some aspects of "progress" that reasonable people have to ask "WHY"?

The future is wonderful. A lot of guys, myself included, think why would I want to spend all that money & time rebuilding an old motor when it is probably cheaper to throw a crate motor in the car and call it a day. I mean I went with a crate motor and decided to go the carburated route & the original V-Belt set up, electronic ignition& other modsso when you open my hood it looks like an original 289/302 motor, but I know it's new & dependable.

I did the crate motor thing in my son's truck, It was a fun and easy swap, that I am sure that I will do again someday. For my current project I am going to build the motor myself, hopefully imparting a little mechanical knowledge to my kids in the process.

I think that by carefully selecting components one can for sure get "more bang for the buck" (especially on Ford motors) by building an engine instead of going the crate route, if my time spent in assembly and "parts runs" is not counted.

It is hard to argue with the simplicity of installing a crate engine, and the waranty that comes with it.

ie: my build includes

408 stroker, in my 351 block, forged crank, H beam rods, forged pistons, roller cam, aluminum heads, roller rockers, high vol oil pump, main girdle, (everything that the Ford Motorsports small block windsor has except valve covers, and oil pan) for about $4,000 + $400 for myengine block. I will have to have the rotating assembly ballanced for I hope not more than another $400.
