Yup, I am using a NOS Volvo one. Way cheaper than the Porsche part, same characteristics.

that engine in the bus was a wild assed guess on the intake runners and plenum!

the runners too big in dia. and long would make it fall on it's face across the board, the small plenum will make the runners "fight" each other in pulses in harmonic phases thru the rpm range.

it would be best to use a similar sized engine to model the runners and plenum on.

The 3.0 CIS system that I am using will pretty much be mimicked. Right size, right parameters. I will be making a bigger, rectangular plenum with shorter down tubes. I am wondering if it is worth it to put trumpets inside the airbox leading into each down tube. (IMG:style_emoticons/default/confused24.gif) This is supposed to help air flow immensely.

if the point of entry for the runner tubes are not radiused you should do something to smooth the air entry to the runner.

The adapters to the head are pretty ugly in their transition. I will post a pic when I get home to show you.

Here are some close ups of the intake adapter. Basically, there is a plate welded onto the top with round holes that transition immediately into square.

I also took a close up of the mating surface to the head. It shows that you can used square O-rings, but I dont know where to get such things. I will likely just cut out gaskets from gasket paper.

Note, this adapter is not the one used in the other guys failed attempt. His were welded in pipes so had a smoother transition.

How about some awesome news?!

After doing the calculations on the adjusted rods, and converting over to the hydraulic stock lifters, the correction is that the rods I need to use needed was .1115" shorter.....the stockers fit! Now I just need my head back so I can finish assembly (IMG:style_emoticons/default/biggrin.gif)

Today finds me with half of an engine done (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/dry.gif) I am mixed about this (IMG:style_emoticons/default/wink.gif)

I love these roller rockers (IMG:style_emoticons/default/smilie_pokal.gif) I got them because they are cool, and they should cut down on heat and valve-train wear. . (IMG:style_emoticons/default/cool_shades.gif)

I also made my own gaskets for the intake manifolds out of a roll of gasket paper I had. Came out pretty nice (IMG:style_emoticons/default/smile.gif)

I am fighting the urge to use my mega-jolt on this engine. If I had it programmed with advance curves already I would do it, but I dont so I would have to do a lot of extra research. Maybe I can install it later when it is running (IMG:style_emoticons/default/rolleyes.gif)

Damn feature creep.

Not surprising after 57 pages and 1133 posts that you'd make that comment. (IMG:style_emoticons/default/shades.gif) If you think feature creep is a problem now, just wait til when you start outfitting it for actual travel.

Nice progress Doc, heads and intake look great!

Dude, your whole automotive life could be described as "feature creep." It is not surprising that it has bled over to this facet of your project too... (IMG:style_emoticons/default/bootyshake.gif) (IMG:style_emoticons/default/drunk.gif)

You know what would be cool . . . if you had Scotty paint it red and black like your logo.

You could program your mega-jolt while he's doing that.
