Looking for exhaust port layout drawing

[tubman]

WOW. 14 posts do do something this simple?

15, i thought they are 45* ?

16. Made a template off the block at the machinist's shop. You know engineers have to complicate everything. 😏

You only need the outer holes so they will do for both sides.

[Ziggster]

Got it. We checked the other side of the block and the outer holes lined up as you said, but I can almost guarantee that I would have drilled out the middle holes, so thanks for reminding me.

You can easily make a template that will last longer if you use thin aluminum flashing sheet, a ball peen hammer and a gasket hole punch. Punch a hole in the flashing at one end first and use that to bolt the sheet to the block so it won't move. Go to the far end and do the same thing at the other end hole. Use the ball peen hammer to lightly tap over the other bolt and port hole edges to get the outline. Keep on tapping until all the holes open up. Just be sure to tap lightly so you don't damage the block. Trim the extra flashing and you have a permanent template that you can hang on the wall.

Yep. After playing around with some printer paper and a pencil, that is exactly what the machinist did, instead just with a heavier piece of cardboard and no hole punch.

Cool. I like to use the aluminum sheet because the holes "don't move" if you have to use it again.

If it were me, I'd clamp an exhaust manifold on the piece of steel I was going to use and using transfer punches mark the holes and them take them to the drill press. Why go to all the trouble of making a template, then transferring those marks to your steel? You have a couple of chances of having something move and be off.

Or if you really wanted to make it complex, create a DXF file and take that to a CNC mill or a laser cutter!

He does not have a manifold, that's what started all of this.

[Ziggster]

Finished off the adapter. Fits great. I just had to trim the corner like in the previous pics, and cut down my 1.25" lg bolts to 3/4". Yes, I lifted with only two manifold bolts and a chain. Lol.

[JSeery]

Looks great!

[Mart]

Only two manifold bolts?

A bit lavish ain't ya? One would have done.

[Ziggster]

LOL. True, but that's what the machinist used. He suggested I make a plate to cover the intake with a couple lifting points which I'll do soon. First, I want to get a dial gage and fixture so I can mark TDC on my pulley, which I may need to purchase as mine is some cobbeled up affair with a third groove crudely welded on.

[cas3]

this one is a bit elaborate, but i hope to use it until my toes point up. cut out to match an intake gasket, so good for painting, lifting, or storing a flathead

[Ziggster]

Wow. That is brilliant. I like the idea that you matched the intake profile. I'm leaning towards painting my block a different colour than that of the heads and intake, so that would be perfect for such a scenario. The adjustable lift is just icing on the cake. Someone should be selling this concept.

Unable to remove my post sorry.
