Thinking outside the box

Tarr,

Thanks for your comments!

This is not an argument... at least, the only thing I am "arguing" is that I think that if EQ can make the heads they're making right now (in cast iron), they could ALSO make a version with taller ports by just adding a 3/4" section to the middle of the existing head and increase the intake port height, and volume, by a lot.

The whole idea is to get more cfm port flow on the intake side without having to move the pushrods, which this would accomplish.

The W-2's are expensive to utilize because they DO move the pushrods over out of the way, but they require special offset rockers to accomplish this. It works great, but requires a lot of $$$$$$$ by the time you buy everything, including the longer valves (not necessary on the econo W-2's.) With the raised port EQ head, the valves and rockers would stay in the same place, laterally. Longer pushrods would be necessary, though. MYABRE longer valves, too.... not sure about that.

I keep saying that I am NOT "comparing" Mopar technology to the late LS-1/LQ-9 G.M. heads, and I am NOT.... But I mentioned them because they do flow 300cfm, and only have 2 valves per cylinder. If they can do it, I think a raised port Magnum head could, too.

That's my only "argument..." a "can do" attitude.

I hear what yoiu're saying about road manners/driveability, and that was one reason my car was not very quick witout a blower; 13.35-sec quarter-mile, through the mufflers on a 95 degree day at sea-level on drag radials.

But, it idled at 475 rpm... and had tons of low end torque due to the mild cam.... made 12 inches of vacuum at idle for the power brake booster.

Since then, I have added a Crosswind intake (Air-Gap style 180-degree), replaced the cast iron 340 exhaust manifolds with TTI step headers, and bolted on a 10-pound boost Vortech blower.

It should have the same street manners it always did (same cam), but if I am lucky, it will run around 12 flat, now... which will make me grin.

But, talk's cheap.... I need to do it and THEN talk about it. It's almost ready to make its maiden pass down the 1,000-foot strip at Centerville with forced induction. Ran 11.0's before in 1,000 feet. Hoping for a 10.0 time card, now.

That is, if the head gaskets hold....:angry7:
