And my wife disposing of the local wildlife. 



Apparently my garage is an epicenter for madness.

You have to copy the "IMG code" of your photobucket picture.  Then paste in your post here.  When you run your cursor over your photo, or if you click on it, in photobucket 4 different image codes should pop up.  You want to click on the bottom one, labeled "IMG code", to copy it.

 Here are my kids in my garage "playing".  These are not posed photographs.  I think my older son has a 1-1/8" box wrench there.

Sounds like a good plan to me.

I gotta ask though, how do your Hi-riser heads and intake compare to Blair's Pro Ports and intake?  I'm not sure I'd make an ironclad statement that since a certain size cam peaked at a certain rpm in a smaller engine,  the same size cam must peak at a lower rpm in a bigger engine.  I think if your induction system has more capacity it may rpm the same or even higher than the smaller engine, with the same cam.  I'm sure you've taken all this into account.  Just curious about it.

I actually think that's a pretty sound statement, given engines that are fairly close in horsepower.  My intake testing didn't show any significant difference in peak horsepower RPM with fairly wide variations in the manifolds themselves.  For example, if you look at the engines tested on my 390 stroker mule in the book, peak horsepower varied from about 420 to 525, but peak HP RPM only varied from 5500-5900 across most of the tested manifolds, such as the Blue Thunder dual plane, Performer RPM, Streetmaster, Victor, and Dove tunnel ram.  The only intake that really fell outside the box was the Edelbrock SP2P.  Generally, the intake just didn't have a real big influence on what RPM the engine made the most power at.

The cam, on the other hand, can easily shift the power peak up or down 1000 RPM depending on duration.  And the power peak with a given cam will always shift down if the cubic inches go up, keeping all other variables constant.

Blair mentioned that he tried two different tunnel wedge intakes on his engine, one for a medium riser and one for a high riser, and he said the high riser peaked in power about 300 RPM higher than the medium riser version did.  That's more than I would have expected, but certainly within the ballpark.  In any case I feel pretty comfortable that given the power targets, RPM targets, and size of this engine, I need to be running quite a bit more duration than the cam in Blair's engine.

I didn't consider just changing the intake manifold.  That would be a very different story.  I was talking about changing heads and intake.  The heads being the more important part.  I don't think the combos in your book are a comparable situation.  Are Blair's Pro Port heads comparable to your Hi-Risers?   You're Hi-Riser heads are over the top in awesomeness in the wedge head world.  I'm not convinced different heads and induction have no or little influence on rpm range.

edit:  This is a double post.  Sorry.  I didn't see my first reply and thought I didn't hit "Post",  so I typed essentially the same response again.

I don't have anything to add other than I really hope you find your "smoking gun", Jay.

I vote 270S based on the cubic inches, weight, and gearing.  That said, I've never driven a combination just like this.

took me over a year to decide after that email , plus I have always wanted a tunnel wedge , that made it even tougher ... I will have one someday , sooner than later :) .... one things for sure , the carbs and linkage will bolt up to either so no-back track there

Maybe we could swap intakes sometime, Tunnel Wedge and MR 2x4, just to experiment?    ;D

when Jay emailed me the dyno charts on his 445 with comp 306s , medium 2x4 verses tunnel wedge , the meduim riser beat it every where except the last 500 rpm in the power band .... I will have a tunnel wedge someday , but its hard to beat the meduim riser on a street driven vehicle , either way the Ford engineers knew what they were doing when they designed those two intakes .... I wonder how a FAST TBI 2x4 system would work on a tunnel wedge ??

I agree.  I underestimated how good the MR 2x4 intake was until I read Jay's book.   I had already bought a Tunnel Wedge and had it ported before I read the book.   I don't regret it, but had I known how good the MR 2x4's are it would have been a tough decision for me. 

The MR 2x4 intake, be it factory or Blue Thunder, is an AMAZINGLY good intake, over a huge power/rpm range.

I'm eagerly awaiting the dyno results too!   Thanks!   :)

Not meaning to hijack, BUT would using single plane common plenum intake like a tunnel wedge make a difference compared to the dual plane MR 2X4?  Would two 600's effectively flow more on the single plane tunnel wedge?

thanks,

Sounds like low 11's, possibly high 10's in pure stock form (read: tires!).  Wow!

I wish Ford would make this car without the Shelby name.

but $2k or there abouts for basically a really fancy carb squirter.
When the only real advantage is a cold start.
And if you can't start a cold Hot Rod Holley FE, well then your just a rookie.
Although a couple of them sideways on a 2X4 would look cool, but then your at 4K. Yikes.

I'm with you.  With EFI you'll pretty much always go slower, but it does have other advantages as Jay pointed out.  My 428 has a 252/260 cam and I can start it and run it in single digit temperatures, with no choke.   It'll also cruise around town at 2000 rpm.  I love carbs.   ;D

Well I think you're on the right track then.   I just got the 3/4 race cam joke.   ::)  ;D

A 4.56 rear gear will get you around 135 mph at about 7400 rpm with 28 inch tires.

I see:

Shifting at 7500-ish rpm if you have good heads, especially with the nitrous.

The lobe separation is tight if you want it to be a "nitrous cam".

I have studs in my Edelbrock heads and they work fine.  It was many years ago when my engine was put together so I don't remember anything very well.  Maybe it was the studs blocking the drain back holes?  I know my heads have some work there.

I don't know anything about belt cam drives.  And I've never had offset lifters or rockerarms. 

What I do know is those heads are full-on bad-ass.   Everything else is just details, IMO.  Can't wait to hear how it turns out.
