Dear Slanted World,

I have posted a bunch of pics on Flickr of my custom "g-force" oil pans from the Project V 66 Valiant (2008 build) and the "V2" 64 Valiant (2014 build).

Also, Brian Mimken was over 2 wks ago (thanks, Brian!) and we did test fitting of Rick Covalt's Hyperpak exh manifolds and head pipe on an engine mounted to a K-frame with full power steering and an AC compressor and bracket on it. We test fit many intake manifolds with those exh manifolds, and with the Argentinian front exh manifold.

The only intakes that did not fit the Hpak exh were the Redline and Clifford 3X2 Weber manifolds. Both long and short Aussiespeed intakes fit, as well as the usual suspects (offy, Clifford, offy 2X1...).

I hope this is helpful to some folks, and feel free to ask questions.

Slant on,

Lou Madsen

Very nice Lou! Thanks for taking the time and effort to check all that out.

Question on the AC mount - is that one of Charrlie_S's mounts?

Thanks Lou, that should help everyone out! I know you hate dealing with pictures!

Also one question on the P/S. This is a K frame for a 67-76 A body correct? Is the early A going to be a smidge closer to the manifolds? And do you think there is enough room to clear the hyperpaks on the early A body P/S? Thanks!

That's some great work!

Did you take pics and measurements of the Hyper Pak and Argentinian front exhaust manifolds?

Thanks, all.

That is a 64 K-frame.

Many pics of both manifolds are in the link listed above.

Yes, that is Charlie's AC mount, which is pretty similar to the Classic AC mount, but a bit more forgiving on fitment/geometry.

All the best,

Lou

That is good. Then the newer A bodies should have even more room.

O.K. So how much interference is there between the H-Pack Exhausts and the Redline Weber manifolds? Is it "fixable" (say maybe with a spacer between the carbs (or Ingelese Fuel Injection throttle bodies).

A side question, if I might about the AussieSpeed Short Runner Manifold with the Rochester TBI adapter on it: Does Aussie Speed make the adapters where the throttle shaft parallels the head and valve cover (perpendicular to yours)? In looking at the old Direct Connection books, the H-Pak Ram Manifold had their AFB Carburetors set up in this manner (with the primaries closest to the left fender, for the best torque). Has anyone done any testing to confirm an advantage to this set-up?

It would take a ton of grinding to get the redline to fit. Maybe too much to allow bolting the rear carb onto the manifold flange... Best to use headers with that intake.

I made that Holley TBI adapter with 3/8" aluminium plate, a hole saw, and drills and taps.

Looking at Lou's (wonderful) fitment pics, it looks to me like one could take a stock exhaust manifold and cut the heat riser box portion off, say the top inch or even 1/2 inch and weld it to the top of the front hyperpack to make a heat transfer system for the offy or stock intake manifold. You'd only need drill a 1/2 or 3/4" hole in the bottom of the newly welded on box (the top of the hyperpak manifold) so exhaust could enter the box as a stock exhaust manifold would. You wouldn't have a flapper mechanism, but that's OK. Given how tall the heat riser portion of the stock exhaust manifold is, you could carefully cut it to perfectly mate with the hyperpack, there's plenty of material for that. A cardboard mockup would provide an easy template for where to cut the stock exhaust manifold piece, so welding to the hyperpak would be pretty clean, tight tolerances, easy welds.

I realize this scheme involves (ugh) welding onto a piece of history, a perfectly designed piece, but you'd have the best of both worlds, the great flow of the hyperpak and the benefit of intake heat.

just saying...

You could also just drill and tap one of the hyperpaks for a 3/8 NPT and simply run a flexible metal (and insulated for better heat retention, since you don't have the thermal mass of the cast iron box) tubing to the heat box, that is, use a plate bolted to the heat box with a similar fitting so that exhaust gets fed to the heat box, much easier if there's room, seems like there is from the pics.
