340 Heads,
I think, or seemed to recall, for some reason, the heads off the later 68'
model year engines were a 'touch' smaller in cc volume. How and why, I can't remember. It may have been just a 'needle-in-a-haystack' set of heads. Casting #'s were the same. But of course back in 69'/70'/71' the NHRA Tech people weren't so 'picayune'.

Ed, NHRA has got some numbers wrong. Why?, I don't know. And I don't know why they don't correct them. Some other heads/brands have the same problems. Some 305 SBC heads can be over right out of the junker they're yanked it from.

My kids and I love Stock and Super Stock. I try to help anybody starting out as much as I can... I would like to see the eliminators stay popular forever. I can speak with authority because I own more Original Mopar Core parts than anybody I am aware of. I have sold core parts: Blocks, Heads, Manifolds to many if not most of the mopar racers on west coast. Also to most of the most respected Mopar Engine builders in the west...you would know their names! My family ran one of the largest Wrecking yards in So Cal. in 1960-1974. Much of my collection of Heads dates back to when these cars were NEW and have Never been touched(Original Paint, still see Head Gasket Imprint). I invite anybody at Vegas Race to come look.....No Secrets Here. Time after time I sold virgin small block Heads (Big Block not a problem) and seen the darn things come up Big....and I have had many disappointed customers! I am not grinding up core heads by the dozen to make then Illegal and lose customers! I am not a Engine builder so I have nothing to gain by lying. How dare you call some one a liar...you don't know me YET! I make it a business to know the Ins and Outs of these Heads and other Mopar core parts---Have for 40 years plus! What have you done to profess to be an expert and to call everybody else just trying to help a guy with advise a LIAR? John Irving Irving Family Racing
PS: There are many reasons some of us take a break (Like Rod) sometimes financial often personal,or Health.... Doesn't make him less knowledgeable . I have known him 35 years and hold his abilities and knowledge in great esteem!

The point I was trying to make was that we have numerous samples of the heads that we are talking about available for inspection...probably more than anyone I know. The point I was making on how we made our living was to explain WHY I had access to so may 30 to 40 year old parts! They were muck easier to find they...particularly if you were in that business. It is not very nice to call somebody stupid that you do not know. Until just a couple of years ago NHRA did not cc the port runners as you well know why would we check them if we knew we had not modified them... further the Chamber in all the heads are 3-4 or more cc over spec allowing you to put a different valve in and adjust the amount you milled the heads. Do you think I am lying about that too. Fortunately my stupidity and lying has not keep us from qualifying in top 10 in First Two 2010 National races and holding a Current National Record with our 360 engine vehicle. But then again maybe am lying about that too ....What has a smart guy like you done lately? What do you race.....I am surprised that I don't know you..... but I have never claimed to be smart.... I just own and sell a lot of Mopar Core Parts. I am currently in Tucson at Div 7 race-- racing 3 stock mopars... are you there...I will be in Vegas Nat'l in April racing 4 stock mopars... will you be racing there? Stupid John Irving ( I could be lying about the name and be too stupid to know it) .

Ed what John is trying to do here is help you,if you can't understand this you shouldn't have ask for help. When someone does a solid you should at least thank him. Claude Ruel

Ed I do not like your attitude .....I started this post looking for a little help and knowledge from some racers, to help me make fewwer and at the least, less expensive mistakes. I was a racer back in the 70s was a nhra track announcer and a div 5 tech guy14 years ago and if a guy came to the tech line with a huge attitude like your i know i would have found many things wrong/////// john has been helpful in trying to steer me the right way with parts and help WHAT HAVE YOU DONE. John you have my 800 number thanks again Bryan

This is one exciting thread.
Much like the 'Bickersons' early radio days!!
Just for fun, I'm going to cc the runners on my #894 heads from
late 68'.
Those 'bastards' better not go over 153cc.
Or I'll pour 'liquid-metal' in there!!
