Highest flowing sbm heads?

Any cylinder head thats going to make ANY power will be “too much work”.

Not to single you out in particular but this has been my ***** about Chrysler guys since I bought my first
car.

The vast majority of Chrysler guys don’t want to buy a real block. So the market volume goes down and the price goes up. Casting 1000 blocks makes the cost far greater than casting 10,000.

These same guys didn‘t buy W2 heads when they were released because they didn’t want to buy another intake manifold and they couldn’t run stock rockers and they had their own headers. But Chevy had NOTHING at that time that would make power like a W2.

And it hasn’t changed since 1979. It’s STILL the same thing.

The cost to build a Chrysler is within 2-3k of a Chevy IF you build the Chevy with equal parts. That means you are buy a “race” block from Dart or some similar brand and not the low dollar replacement block.

That means you have to use an equal head package.

Never once have I had a Chevy guy say no when I told them they needed an aftermarket block. Not one time. Same with rockers. I‘ve never had a Chevy guy not buy shaft rockers when I said it was needed (it’s always needed as stud mounted rockers are now and always have been junk) and yet guys on this very forum won’t buy a W2 head because of rockers.

Its a damn shame too.

Now que the flow is what matters, grind on your 273 castings for 6 months to make 450 honest HP crowd to defend their lunacy.
I'm not worried about being singled out. You make good points without being an ***. You've been a good advisor to me so far on this site and I appreciate it.

I actually would pony up the bucks for a race block. Truth be told if and when I do get budget to do this build I'll still consider that route. No reason I couldn't put my all forged recip assembly into a race block right? However, the race blocks tend to be unicorns or very cost prohibitive at the least. One begins to look at other options. For example just going with a late model engine to begin with. The most recent iteration if the hemi head makes huge flow numbers.
