Re: H-I-J '76 Nova re-fit.
Today we pulled the redneck A/C from the rafters for what will surely be another hot summer. Started pulling Racepak bits out of the boxes and found a spot for the logger just for something to do. I'll update on the block situation tomorrow, if I can pick one up local I'll have a plan in place pretty quick.

Re: H-I-J '76 Nova re-fit.
So was the #3 main cap broke?

Re: H-I-J '76 Nova re-fit.
If something is in fact wrong with the block, I cannot see it. Something is definitely wrong, but as usual I can't find a smoking gun.

Re: H-I-J '76 Nova re-fit.
Definitely frustrating to say the least.
Great thread and good luck getting it back on the track! |

Re: H-I-J '76 Nova re-fit.
Not trying to go off topic however since so many knowledgeable / helpful people have responded to this thread, how does one identify a production 4 bolt block w/ nodular caps ?

Re: H-I-J '76 Nova re-fit.
The caps with 2482 cast into them are nodular as I'm told.

Re: H-I-J '76 Nova re-fit.
Picked up a block today, .030 over newly machined with new freeze plugs and cam bearings installed, but looks as if it's been sitting in a shop for some time. Here's the plan, about an hour away there's a guy that I know of that has a strip tank for car bodies, it TOTALLY strips paint and rust from steel so I've pulled all plugs and cam bearings out of this thing and I'll drop it to him tomorrow to see how it works removing rust from blocks. Hopefully cleaning the water jackets so it's ready for hardblok on the inside and super clean everywhere else. some probably think I'm crazy for using a stock block, but I promise I have a plan. This will be a backup engine (if it ever runs) to a real nice one later. Nothing special here, certainly no worse than the 2-bolt we had.

Re: H-I-J '76 Nova re-fit.
Yes Todd is correct. Three center 4 bolt caps have 2482 cast into them and usually N also. Nodular iron is still cast but better than plain grey iron.
Some caps are really pretty weak. I’ve taken engines apart with a broken center main cap and the engine was still running !

Re: H-I-J '76 Nova re-fit.
Ok, and the caps with the #3412 cast on them are the regular,less desirable type.
