« on: September 01, 2011, 03:00:24 PM »

Pic of a '70 318 I've been offered w/ supposedly 8,000 orig mi out of a
Cuda transplant to a 440... why are valve springs blue?  Is this
credible??

The color designated the spring tension.It wasn't run long enough to wash it off.Why is the block so dirty?

I was going to say the same thing. If it is a low miles engine, it wasn't put together very well to begin with. And yes, the green valve springs were considered the heavy duty valve springs or battleship valve springs. Check to make sure it is indeed a 318 and not a 340. They may have added them because it was a manual transmission application, but not truly likely. Surprised that if it was a low miles pull for a bigger engine swap, that if it was a 318, why pull off a 2bbl intake? Leave it on for protection, so a simple check would be worth the effort, just look to see if you find a casting of 318 or 340 on the side with the other casting numbers that protrude from the block.

Ya I thought it was odd that the intake & carb was gone too, I
surmised maybe they kept it to eBay or something, otherwise why save
it... and also the dirty condition of the outside is odd.  I'm
guessing maybe it's 8000 mi on a rebuilt engine?  and not an all
original. The guy is someone I know and he is honest, but he got it
from someone else who told him all this, so who knows. He only wants
150 for it, but I'm undecided. Be really cool if it was a 340, but
can't imagine they wouldn't know.

If one cares about the quality of a rebuild, the outside gets cleaned. If a quickie rebuild, like timing chain and valve grind, no, but if that were the case the heads would be cleaner. Since the outsides are off, look at the cam lobes through the lifter valley to see what they look like. You have to check the cast numbers to verify what engine it is, easy enough to do, no scraping necessary, the engine size is cast about one and a quarter inch tall numbers in the side of the block for small blocks, either 318, 340, or 360, and probably 273 (but not positive on that). I do not know of any 2bbl intake or valve covers worth eBaying off a 318, even if it was in a Barracuda.

I'm thinking it may have truly been very lo-mile and used so little that the valve cover gaskets dried out and oil leaked all over the block.
Unfortunately it's 4 hr away on Long Island, a real hell hole to drive to, so I have to go on his description... I hope to have him check the stampings, but if he discovers a 340 the price might go up!

Ask for pictures of the casting numbers so you can be sure it will fit

Correct. The bluish/green valvesprings were the low-po version w/ NO damper speed pro VS510 replacement.They had 6-7 coils. The 340 spring was natural WITH damper and replacement is VS 678 which was 5-6 coils. The lo-po bluish/green ones were on the B/RB ones also. Krautmaster had lots of info on these. I magnified that engine and there is no raised casting markings such as what a 340 head would have,be it X,J,A,etc. Also the intake ports are of the smaller height and width compared to the large port heads. The rockers,shafts etc. looks like there is no varnish or heat burned oil on them. Looking in the exhaust ports i could see only carbon on the valves which leads to believe the valve guides are probably in good shape as there is no oil residue. Most small blocks started to leak out of the valvecovers the day it left the factory. I don't know why it took them till about 92' to switch to the Magnum 10 bolt valve cover. I would bet my bottom dollar this is a 318. If i could see the damper,that would tell you for sure.

Yeah, the ports are pretty small looking, but the block itself may be a 340. I just don't buy that it is that low mileage engine, and yes, valve covers leak, but to look that bad, well, unless it was a gusher and going through a quart of oil every 500 miles, it would be something fixed a lot sooner than this, insides looking clean is not an indicator of the exterior condition, good old Pennsoil would keep an engine from the 60s and 70s looking this good for a long time. I just can't see taking the intake and valve covers off and leaving them off considering they were simple 2bbl pieces, then leaving them off. They are only worth the cost of scrap, so keep the engine buttoned up a little better than that. If nothing else you have a clutch, pressure plate, flywheel, for a manual.

Here's a thread of mine from 2009...when I had a bad timing cover leak antifreeze into my crankcase. Compare my 85,000 mile 1969 318 and see what you can learn. Mine has the blue springs too...
