I've given away C4's that needed rebuilding.

I'm not sure what year they went to the 6 bolt bell housings, but I know there is some market for the 5 bolt ones. A buddy of mine was looking for a 5 bolt block for a Sunbeam he is restoring. I found him one for $450 that needed rebuilding and he said no. I don't know what he paid for the one he eventually bought.

 

I looked at mine and it is the 6-bolt bell housing.

 

C4's aren't generally worth anything if they're done. I've seen them go for free to 100 bucks, at the most.

But a 289 can go for a bit depending on what it is... long block 289s go for ~400 here in california all over craigslist, as long as they're operational.

 

I managed to get a 289 with C4, drive shaft and complete 8" rear end for $325. The 389 needed all the pulleys, brakets & a distrubitor. The C4 and 8" were complete.

 

Thanks for the help!!! I was thinking around $500 for them so it is probably a good starting point.

 

i read somewhere that 289 engine parts are harder to come by cuz for performance ppl always build 302's. it was a recent post i think... but yea 289's are worth more to ppl restoring the car as factory... i have my 289 out of my coupe, and i believe its the orginal one. i was going to "freshen" it up to keep as a spare so the car is always on the road.. it was running fine when i yanked it... i to have the complete 289 & c4 fully 100% good to go.. might be worth keeping around... or ask for a decent price...

 

I had originally planned on keeping it around but the $'s would come in handy with the restoration costs. Since it is a 'C' code car the motor is not going to make the car worth what 'K' or 'A' code would be. No plans on selling anytime soon.

 

Dont know the value much but i did run across a few sets of 289 heads and a complete motor that was getting assembled before the ole fella died at an Estate sale I picked up n put in my shop..

 

Yea, $500 is a good starting point. Might expect to have to separate them if someone is looking for just a motor or trans.

 

What are you going to use for a front cover on the 5.0?

Anyhow.... like it's been said on the C4.... up to $100 is about the going rate. With regard to a '66 289-2V that needs a rebuild? $100 as a core, unless you're lucky enough to find someone who needs a date-coded block and heads for their concours restoration project. Frankly, I'd keep both if they are usable. On a rebuild you can swap in a 302 crank, keep the longer 289 rods and get some pistons that don't come up past the deck height. Open up the exhaust on the heads, port match and you should have a peppy little engine. Keep the C4 if you aren't on the 4-lane highway more than 25% of the time. It's lighter, has less parasitic loss and doesn't require the installation of a TV cable and associated adjustments. Unless you're on the highway all the time I don't think you'd even notice the difference in fuel mileage.

 

I put a fuel pump eccentric on the cam and used a 66 cover with the Scott Drake conversion balancer with the 50 oz weight. I that way i could keep the stock appearance. This one is going to be for the wife and we live about 10 miles from town so it see quite a bit of cruising time. And the 2.8 highway gears would be way too boring to drive!!!!
