Hey Carl, I just noticed you are from Manitoba. How far away are you from Minot ND? You get that bracket car together you can come down and try it out there next year.

[Mr. P-Body]

Yup, there are two "882" castings. The front portion of the number is different. The "good" (a relative term) is the "heavy wall" casting. The other is the "thin wall", and is probably cracked. You can tell them apart by looking at the edge that "hangs" over the outer side of the block. If it's flat, with one "dimple" in the surface, it's the heavy head. A scalloped surface is the light one.
We do a fair number of lower-level circle track engines, where rules are enforced. The 882s ar "legal". They usually CC at 76. The rules require a minimum of 75. The more popular numbers for such a class of racing are 487(x), 993, 997 and 336. 441s are considered the BEST factory large chamber small block head, but are precluded by rule. 882s don't have the better runner shape and bowl design of the more popular heads.
The 601 casting (305) is the "HO" version. It has nice runners, and a 54 CC chamber. THAT'S the head 350 guys are talking about. Any of the other 305s aren't much different than the 350 stuff.

Is that where you are? I wasnt't going to ask, because some guys want to remain somewhat anonymous. We are about 100 miles north of Grand Forks, on the Canadian version of I29. We usually get to Minot at least once a year. We were there in Feb/04 for the Newsboys/Rebecca St. James/Jeremy Camp concert.

Don't tell anyone, but before my 64 GTO clone convert, I did all Canadian Pontiacs with Chev big and small blocks.

I figured we were on the right track with those heads. Thanks for the info. I don't know if we will drive that far to race. These are young kids who are deemed to be "at risk to offend" so we spend some time mentoring. (Fancy way to say we get people to donate and we build a race car with that money!)

This thread is hijacked now anyway (sorry), but do you know anyone around Minot who bought a white and black 64 GTO convert with no powertrain a few years ago? I looked at it when it was for sale in Grand Forks. Just didn't have the cash, time, or space right then, or it would have been mine.

[Jeff Walker]

No Carl I don't know about the 64 convert you mentioned. Actually I live about an 1 1/2 hours south of Minot.

[Carl S]

You must almost be closer to Bismarck then.

We get there sometimes too.

Carl

[Jeff Walker]

Yep, about an hour away from Bismarck.

041 heads are closed chamber heads and will bump up the compression and are the best heads chev made so dont throw them away also if u'all have any work done to chev heads have them magnifluxed as they are prone to cracking once I went thru 4 heads to get a good one had to go to the junk yard and pull them and then I rode them to the machine shop on my old honda across my lap DAMN I MISS THE GOOD OLD DAYS

DRIVE IT LIKE U'ALL STOLE IT!

After pulling the heads, i just cleaned them up a bit with the wire wheel and put them back on with new head gaskets. Torquing heads bolts put a kink in my back for 2 days
