Yes, the 302 is drivable with the wrong balancer on it. Let me rephrase that, it is drivable if you ignore the vibration. And it can be an easy mistake with the classics. Someone pulls a 5.0 from the junk yard and when the front pullys do not line up, puts the 289 balancer on it with the front assessories. Of course, it will screw up everything inside the engine. Bearings, rear main seal, yaddie, yaddie, yaddie

If you have any mechanical inclination, you can buy a 2-ton harbor freight lift and pull the motor yourself. I recommend the 2-ton because it extends out further where as the 1-ton is not quite long enough. Watch their adds and you can buy it for under $200. And if you wanted, you can sell it on CL afterwards.

2 ton Capacity Foldable Shop Crane

I wonder if the statement was, your engine is what is throwing everything off, as in, the engine is the cause of the vibration, not, your engine threw everything off of it.

bacchus203- That is a correct statement. They said that the engine is the cause of the vibration. I should have phrased it that way instead.

Just rent a engine hoist and do it yourself. Its what me and my son did. I pulled it out one Saturday, had it rebuilt and installed it a different weekend. This is before all the crate engines that are available now a days, when you used to have to take it to your local machine shop. I found the following people:

$40 bucks a day. Man for 9k I could get a 347ci stroker with some nice AFR 205 heads and probably enough to put a Paxton supercharger on it.

Holy smokes 9k?! I'm going to have about 7k (excluding fuel system) in my 408 that started with a reman'd block...that's installed and on the ground.

Go get a hoist, pull it, read up on rebuilding a windsor and get to it. Like most have said, doing a 'refresh' on the engine, a first timer taking their time could do it in a few days (excluding waiting on the machine shop) for around 2k. That's from pulling to back on the road. should really press that shop on why they think its a total rebuild...and want you to pay a learning tax. Could be something as simple / dumb as a bad motor mount.

Just as point of reference I cracked the block on my 347. New dart block, forged crank, cam, gaskets, machined and balanced 4000 all in by local engine machinist/builder. I pulled engine myself though. I'm doing a 67 vert now. Doing a crate next time. Unless you are looking at a getting big power I would just get a crate from jegs or summit. Mild 331. If you go to much hp you will need upgrade tranny, rear end.

I purchased my 67 fastback a few months ago and realized that it was very shaky when driving and that it had a pulsing sound. I did all the usual things like have the driveshaft balanced, replace the ujoints, etc but it was still there. It has also had problems with the oil pressure dropping to zero, overheating, etc. So this week I took it to a very reputable shop here in town and they are telling me that my 302 is shot and that is the cause of my issues. They are saying that it is a later model engine and that it has thrown everything off... Now the issue is not that I do not believe them, because I do, as they have been highly recommended by several people. The issue I am having is with the replacement cost.

They are saying it is going to be between 8-9K to tear down my engine, reuse the block, get it installed with a new water pump, fuel pump, etc and get it running correctly. Does that sound right as far as pricing is concerned? I am asking because I genuinely do not know. I know that I can go online and find a turn key engine for 5-6K but obviously that does not include install, so I am just at a loss for what to do...

Could really use some help on this one... I don't exactly have 9 grand laying around, but I really want my car to work correctly as well...
I still have my receipt from my recent rebuild... had a mechanic friend pull the motor and install it again, and a shop rebuild it. Total cost was less than 5k (which included a lot of random other stuff, too). The total cost for the rebuild itself, which included fixing up some serious issues with the heads, was only 2958.66. This was from a very reputable shop, and I had to wait a month or two the shop was so backed up. This all includes a valve job, milling the heads, balancing the crank etc, boring the block, grinding the crank, decking the block, the whole rebuild kit including pistons and rings and such, a cam, etc., etc., etc. It was very complete and I couldn't be happier.

That all being said, 9k sounds absolutely insane. You could get a killer crate motor AND have someone install it for that price.

I'm not an expert, but I play one on the internet.

Good to know. I've never used except to resize some piston rods which they did a credible job on. If I do another motor, I would take it to Wells in Duncanville.

$9k? Whoa that is very bad.

I did a high end 5.3L LS engine build at about $5k. This is forged pistons, forged rods, head studs, balanced/blue printed, etc.

The same shop is quoting me about $2300 to rebuild my 1968 289 with new cam and unleaded valve seats.

In both cases, this is me dropping off a long block plus intake and picking up a ready to bolt in engine.

FWIW, this is outside of the Sacramento, CA area.

I'd also give a nod to Calvert. They haven't built anything for me personally, but I've have friends who had great luck with them. I plan to use them when the time comes.

Find a real shop & have them check out your current setup - you may just have the wrong balancer on it. If it turns out your current setup is bad (i.e. really shot) you have a lot of choices. You need to decide what you want from your new motor and build one accordingly. $ 9k+ is too much. Good luck.

I'd love to see you do this yourself, you'll learn a lot.

Pulling the motor, breaking it down having a shop rebuild it with mild performance adders, then you reassemble and install it will do wonders for your confidence.

There's NOTHING to these old cars, can do this.

Short of the hoist, common toolbox tools will get you there.

Rebuilt/modified a 5.0 roller, rebuilt a T5, bought a rebuilt 3.55 Trac Lok, ...everything for 5k ...installed all in 2 days... 9k is stupid high.

If you have an interest in DYI project, you'll save a bunch and learn a ton.
