A local hot rod shop has a 427 out of an early 60s Galixe with the following specs.
bore=.60 over
stroker crank=total displacement is 581
rods=Leman
cam=solid lifter.
intake=two four barrel holleys

Motor has 0 miles since rebuild and is balanced & blue printed and complete ready to drop in. They want $7,000. Is this reasonable. I know 427s are worth a lot of money but is the motor really worth 7K? The hot rod shop is convienced it is worth 10k but the guy needs the money. I do not think he would go lower than 6.5K Thanks.

You might want to talk to them again. I don't think you can get 581" out of a 427, maybe 481"
The price doesn't sound too far out of line for a 427 though.

i think it may be easier to drop the trans than to remove the engine
remove flywheel or flexplate and replace galley plugs. a major job with engine, a minor job with trans.

 RE: 352/390HP heads! -- Mike McQuesten, 05/15/2001
The cam is a good one. It's a bit lopey but I had one in a 427 and it was very streetable and reved well to 6,200. But now lets talk about those COAE-D heads you're thinking about. I'm guessing here but the cc on those heads is around 57-58. They are compression ratio makers to say the least. They were stock on '60 HP 352 with flat top pistons, and stock on '61 HP 390, 375/401hp and were used with dished pistons on that '61 -'90. These HP engines were rated around 10.7:1 I think. Those heads on a 428 w/flat top pistons will be very high CR. Not functional on anything but high octane racing fuel. Maybe your machinist can dish the 428 pistons or you can have a custom set of forged made, I would run forged pistons with the C-ratio you're going to have with those heads.
I'll admit that I'm running these heads on a 427. But I'm running C3J marine/industrial forged Ford pistons. They're dished similar to the '61 390 cast pistons. My machinist worked the compression ratio with the COAE-D heads(with 1.66 CJ/LR '27 exhaust valves) to be 10.5:1. I know I'll have to run high octance good stuff for most driving. But I had to do it. My 427 is dressed as a 352HP for a genuine HP '60 car. So the HP heads are a must for me. I'd recommend using a set of C4AE-G heads which are commonly available in bone yards. Big CJ valves fit nicely in them and the combustion chamber works well with 428 pistons. Still I think you'll have over 10.00:1 with flat tops. Use forged pistons. I'll trade you a set of C4AE-Gs for those COAE-6090-Ds?

 RE: mr.ford can you help or someone please -- BOB HOPKINS, 05/16/2001
You better be buying a bunch of race gas and octain booster your going to have some compression, I think I would look for some head's with bigger chambers and some replacement pistons with the bigger 12 cc dish and lower compression.
MY $0.02
 RE: mr.ford can you help or someone please -- Dad, 05/17/2001
Gerald, The 66 T-Bird had pistons with approx 13cc dish + 2cc's for the .005 deck height, using a head gskt compressed to .035 & the D heads you would have approx 11.40 to 1 comp. stock would be 10.17. the 66 428 T-Bird heads had 71.2 to 74.2 cc chambers I used 72.5 for a realistic number. What I would recommend is the aluminum Edelbrock Heads they come in 2 diff Comb. cmbr sizes. 10.0 comp should be ok using the aluminum heads & 92 octane fuel. The power diff between the D & Edelbrock heads would be big time. Well worth the money as they outflow all the FE heads out of the box and can be made to flow 350cfm on intake and 250 exhaust quite easily (@ 28"h2o) The D heads are just to outdated to use with todays fuels and technology.. Dad
 RE: mr.ford can you help or someone please -- kevin, 05/17/2001
This cam was offered though Ford as a all around replacement for hi performance. It was an offshoot of the original 427 2-4bbl low riser cam. The difference between the two was that the Galaxie cam was ground on 114 lobe centers, and the C4-B cam was ground on 106 lobe centers. This was due to the lower octane that the Ford GT was forced to use (rules) so they dropped the compression to 10 to 1 from the original 12 to one, hence the nickname "LeMans" grind. It was ground for Ford by Holman-Moody and if im right it was ground by Larry Wallace the cam grinder there. He told me this info 30 years ago. He said that he ground these and the C8AX-D cams too. It works great in everything that I ever ran it in.

The machinist said it would not be a problem if I used it as long as I wasn't going to have forced induction or high hp motor and race it. Any opinions on this? It is going into a street driven r-code Mustang.

It's cool that the crack was found.

That crank has life left in it in a cheap 390 stroker build-up with cast iron heads with headers and a nice aluminum intake, but not in a CJ of any kind. A good baffled-T oilpan is worthwhile insurance on the cheapo 390, though it'll certainly be destroyed in the explosion.

Assuming you get the crank at half price (maybe $200), you've just saved $200, but the whole engine build cost maybe $5000. When the $5000 is lost in a catastrophic failure, you'll need another $5000 just to get running again.

There is no economy putting a bad crankshaft in a valuable motor. If you want to buy it, that's fine. Put it in an engine that you can afford to explode, such as that core-shifted 390 block. It may never fail, but if it does, you're not gonna be kicking yourself forever over it. Instead, you'll be saying, "I knew it might do that."

Cracks form for a reason in iron. Either it's been overstrained sometime in it's 30+ year lifespan, or maybe it had a flaw in it's casting structure and the crack is now growing like a crack on a windshield. No matter what - it's a timebomb. Make sure you put it in an engine that can handle that factor.

Man, it would sure be a bummer to build a nice CJ knowing the crank was cracked. You'd never want to stick your foot into it or rev it out the way CJs like being revved out.

Thanks for the info. Does the typical machine shop have the equipment to x-ray? Is it called something else? How much does it usually cost?
 RE: Have the crank X-rayed -- RJP, 05/15/2001
Don't know what the "trade" name for x-raying is and most machine shops will not have this equipment. You will prob. have to check with a Industrial testing lab and I don't know what the cost would be but to save a hard to find crank it might be worth it. Also it would be a shame to throw away a crank that had just a surface flaw or fissure.

Hi guy's,
I've got a warmed over 390 in a 67 GTA, headers, performer intake, carb, mild cam etc... Starts right up, no smoke out the tail, no drips on garage floor, but I seem to have lost a quart of 15-50 in 200 miles. Is this acceptable? The engine has around 5000 miles since a rebuild, runs strong and all seems well.
WHERE DOES THE OIL GO!
Thanks in advance
 RE: 390 oil loss mystery -- Lou, 05/11/2001
If you are sure you have no leaks, I would check the PCV valve and hoses to make sure they are correctly installed. A quart in 200 miles makes me think the oil is being burnt a litle at a time but at a steady rate.
 RE: 390 oil loss mystery -- John, 05/11/2001
I had the same problem. Too much oil to the heads and is drawn down valves and for intake gets burnt with smoke, with exhaust(yes, it can get sucked down the exhaust...think exhaust flow, not pressure), no smoke. You must restrict oil to the heads, plus type of valve seals affect it and did you install oil drip trays? Modern rings may not fully seat for 1000 miles or more, although most of your oil loss is probably down the valves.

seal it as it goes through the gasket so you might not notice a loss in manifold vacuum. worth a look.
 RE: 390 oil loss mystery -- Steve, 05/16/2001
I recently stopped an oil loss on my 352 by changing the fuel pump. Apparently the diaphram was seeping. Went to an electric pump and gain about a quart a fillup. Worth a look?
 RE: 390 oil loss mystery -- Dad, 05/16/2001
TD, Do you happen to have adjustable rockers on this engine? If so thats most likely the problem as with them and without plugging the oil galley holes you will get to much oil up top to the rockers flooding them. This can be fixed by installing a Holley jet into the oil hole in head restricting the flow. A 65 to 80 Jet should do the trick. If no adjustable rockers you most likely have a ring seal problem. Time and time again I see where the engine builder puts too much oil on the rings and in cylinders, this will cause rings not to seat. This step is as important or more important than proper cam break-in. What I have found best is a very light film of WD-40 On cylinders and nothing on rings. (a small amt of #10 oil can be used on skirts)This will get you the best ring seal. Most people think the ring actually breaks in but its the opposite where the cylinder fits to the ring. Do you have access to a cylinder leakdown tester? If not borrow or buy one and you should have under 5% leakage. Leakdown rates around 15 & up show improper assy or cylinder finish/bore lr
