Naw man, you don't have a set of $1600 J heads. You only paid $1000 for the Edelbrocks, which are worth $2100. So that $1100 savings comes off the price of your J heads making them just $500.

Not now... It was early in this century. Stock headed compression early 340, xe268H cam, air gap and headers making 390HP. Nope. That's a bit of the snarky response about the software.
So the "stock" heads in this exercise appear to have been massaged a bit. Oh, now the numbers make a bit more sense.

That would explain why I've never seen one at church...
you at the wrong church then brother!
need to come down to worship at "Our Lady of Blessed Acceleration"

I was thinking Guy Car Math is 2600 ÷4 heads.
So $2600÷4=$650. When you figure in current price with inflation almost free. If the wife ask how much did it cost to buy um? They asked me to hall them away?

If it has tits, it's a liabilititty.
The 1.88 360 heads were worked some?
Nah... lol

Here’s my first interaction with Westech, back when Brule and I still had hair, so circa 2003ish. We had an engine on the dyno for our race truck. Steve was tuning it, and off road magazine was there writing an article on it. Barry grant had given us a carb to test and said it would be xx better than our carb shop 750. It made zero, nada, nothing. Actually lost a few at peak. The magazine guy asked Steve to cool it down and make a hero pull so he could write that the BG carb was the hot new ****. Steve threw him out of the dyno cell. That’s why I defend them like I do.

Another point I’ll make, Dulcich is well known for saying he “cleaned up” a set of heads when in reality he went hog wild on em. I don’t know him personally but have heard that many times. I don’t know if that’s the case here or not, just saying we’ve joked about it occasionally. Remember when his offset edlebrocks made over 600 on pump gas on 408 inches? Everyone said that was a joke. I watched it happen. The guy knows how to make air move through a head.
The ol Columbo street racing schtick.
It's just a 318. Took that 383-2 out of my moms polara station wagon. It's a 396 that has a miss right now (really a 468). You know the angle.
but in my case... it really is *just* a 318...The ol Columbo street racing schtick.

I’m not sure what we’re referring to now. The two old articles? The first probably had x heads with a good valves job, new valves and stuff and not much else.
The article I posted was the same motor and they then swapped a set of iron heads he ported on and the rowdy MM lobe solid cam.
For the new article, if the heads were massaged a bit then that makes the AFR heads even better coz they made 63hp more with the swap.
Btw, checked the specs on the xe268, 224/230 @.050, .477/.480 lift.
That’s a pretty nice cam there…

The truth is, there's a lot of guys on here that are close-minded and set in their ways and really not interested in trying to learn anything new. And when you suggest something that refutes their beliefs -- and that is what they are -- beliefs, You make those kinds of suggestions, they take it as a personal attack. And defend themselves accordingly, even if it means disparaging somebody or someone or a business that they really have no clue about.

I don’t carry any ill will, some people repeat stuff they’ve heard, some may actually believe, and some may have personal experience. We all haven’t seen everything. I try to keep at least a small portion of my dumb head open to learn new things, and hope others try to do the same. I will however share my personal first hand experiences when the time is right. Seems the time was right.
I'm actually surprised how many don't want to learn more, I get in so much trouble for questioning many of these held beliefs
it's because nobody wants to sit thru math class again.I'm actually surprised how many don't want to learn more, I get in so much trouble for questioning many of these held beliefs

Mopar rated the 340's at 275 hp and 340 ft.lbs.
They also spec'd them at 10.5:1 compression with 63 - 65 cc heads., but most stock 340's had 72 - 73 cc heads at about 9.5 : 1 compression from the factory, 535 and 585 cfm carbs and made about 275 HP.
You could blue print the engine, mill the heads to 63 cc's for 10.5:1 compression and still be NHRA legal as per factory specs. With the bigger '71 thermoquad these NHRA prepped 340's would certainly make over 300HP.
I have seen about 5 videos where stock 340's dynoed from 274 to 284 hp. Maybe there were some early stock ones that made 320HP?
Maybe Dulcich lower compression 340 with the comp XE 268, different intake and carb made 100 more hp than stock.

Not saying learn from me, I’m a amateur, but math and engineering go hand in hand

There’s many different types of learning. I learn much, much, more from practical application than I ever did in any of my engineering or math classes. But that’s just how my brain absorbs stuff.Not saying learn from me, I’m a amateur, but math and engineering go hand in hand
look Mr. Hand, all i'm sayin' is that if i'm here and you're here isn't it our time?Not saying learn from me, I’m a amateur, but math and engineering go hand in hand
Yep. Your truck engine carb/dyno experience was after the dyno issue had been identified and corrected.
I still get ribbed by some for a bonehead move I pulled street racing 40 years ago. Went to lunch with a friend, on the way to the cars on our way out, he spouts off with "turn on the fuel pump." Car had a mechanical pump, but would drop dead at 1000-1100 feet... yeah it shut off. They don't let me forget.
