1969+ 427 blocks (industrial, marine, service, etc.)
Is anybody familiar with the reliability and/or performance expectations of this vintage of 427 blocks?

Welcome to CC!!
427craze,
You have definitely found the right place! Welcome to CC. I myself have a 427 and I continue to learn something about my 427 every day. There are many experts on this site so sit tite and be prepared to answer some questions, take some pictures, and you'll be amazed at what you'll learn :3DSMILE: :3DSMILE: Best of luck, Charmer |
Thanks Charmer, I do look forward to learning boatloads of stuff on this forum.

My tunnelport is based on a marine block.I had the oil passages opened up,and it is quite a rugged piece,a little heavy though.
|
was your marine block originally drilled as a side oiler, or did you have to get this done yourself, or is this what you mean by "opening up the oil passages?" Thanks for your help era
|
427, again, as I said in the e-mail, SO refers to the casting of the block. SOs have the (oil passage) raised ridge running longitudinally down the left (driver's) side just above where the oil pan mounts. You can't drill that, it was cast that way.
|
Yes I got that part, so if it has that ridge there is no doubt it is a true side oiler. Thanks Clay.

There can be a doubt, even if it has the ridge.
Fact is, sideoiler, centeroiler, they either will work just as well. From some points of view, a sideoiler is not the block of choice. Post 69 blocks should all be hydraulic lifter blocks. Another fact is: if you're buying a 35 year old block, no matter what sort of ridges it has, or webs, or paint daubs, get it sonic checked. And it sounds like you don't know a lot about engines, so I'd invest some money in a local expert to examine and check any 35 year old block before sinking the thousands of dollars someone will be expecting you to pay for it. THINK, it'll be the foundation/basis for your entire engine and vehicle. If it's bad or lacking, the end result will be bad or lacking. |
Right. It is actually at the machine shop getting checked out right now. Thanks for the help guys. So either one will perform equally well? I 'm not going to be going to the track and stuff. I just wanna haul a@#$%% everyday!
|
Sorry, I forgot to ask, could you guys help me to briefly outline the pros and cons of a so vs a co? Thanks guys I appreciate the help!!!!
|
Either will haul ass. Because of history, there's a bigger demand and hence higher resale value for SOs. Doesn't matter if you want to just drive, they're both desirable, but from the crossbolts and inset allen bolts you described in the ridge (in your e-mail), you do have an SO.
If you do want solid lifters (pre-68 blocks), you will need to convert that hydraulic lifter block. Any shop with FE experience will know what to do. |
