H-I-J '76 Nova re-fit.

Sorry about the updates or lack thereof. Work has been nuts so time is limited. Weather is getting hot so my energy level is nonexistent, nevertheless I am working a little and we're pretty much ready to go back together AGAIN, hope to get some of that done this weekend. I haven't really done much to change anything and everything checks out so at this point, I have a positive outlook and low expectations. This is the last time I'm doing this.

Don't get discouraged Todd...

Drag Racing can be a real difficult challenge but eventually if you keep trying you'll succeed......

Been there, done that as they say and for me its been many times....

I hope you get better results when you get it back together....

Todd and Autumn,


Knowing this engine experience has been painful and expensive for you folks. Stout hearts and you can overcome this.


You made commented that everything checked out as OK and I assume within specs. Since the oil filter flow capacity has been addressed, how about this little detail to consider. What are the bearing clearances vs the SAE wt of the oil you have been using? Some folks swear by the water type viscosity oils, but if the clearance is large, they can't maintain an adequate hydrodynamic wedge and will skin the bearings up every time.



Hope it proves to be something simple like described above and that you can solve it and get to dyno time and racing soon.



Best of Luck to you both.

I am going to a higher weight oil this time around.

FINALLY! I had a day I could get away from work so we finally saw some forward progress. Checking clearances, got the adjustable guide plates welded (I'll get a pic tomorrow) and made a puck to install cam bearings. I should be able to work all weekend so I'll be back with updates.

[Nmbr1GMfan]

As promised welded guide plate pics. Spent the day frustrated, all we had to do was check the mains and start assembly. #3 main seemed weird in that the cap didn't snap in the block, I could push it in real easy, wasn't like that before, and the bearing was .0005-.0007 tighter than the rest. Pulled the bearing, re-torqued and the bore read .0005 tighter than when it was align honed. I replaced all the new bearings with the old set of King's I kept and although they seemed to check more consistent betwen all of them, #3 was still screwed and for some reason everytime I torqued the mains it comes back with a different measurement. Engine pic is of it being checked with the King bearings. The camels back... it's broken!

Todd,
I'm so sorry to read of all the issues this engine is producing, you are a trooper. Where does one go as of now?

Wishing you all the best,
Glenn

At this point Rich it seems I might be too dumb to figure this out hahahaha. If this doesn't work I'm throwing the whole short block in the scrap bin.
