Intake Fitment

huh... when you put it like that it doesnt sound as complicated as my brain was making it. Thanks for that!

Clarification. They can get real close on estimating the miss alignment portion with the pictures you have. They cannot really tell much about angular fit.

The machine shop mentioned something along those lines early on in our discussions. He currently wants pictures to see if the intake mounting bolts were contacting the mounting holes in the intake and they were. I just sent those pictures off last night.

However, the engine is currently in the car and an hour away from the machine shop. I hope the machine shop has a better way to measure the angle difference than just an "eye balling" because currently I dont have a way to get the engine out and too him.

I eyeball every one of them. Every engine I assemble gets put together at least three times. I dry fit the intake without a gasket.


If the bolt holes line up perfectly I know I have to machine the thickness of the gasket I’m going to use PLUS a clean cut.

In other words, I make sure the manifold surface has fresh materiel all the way across and then I take off the gasket thickness.

If the intake is sitting higher than the bolt holes in the head then you add that much more to take off.

If only the upper half of the hole on the head is showing then I know I need to take a clean cut plus the gasket thickness plus half the gasket thickness.

If the manifold is low then you take off half the gasket thickness plus the clean cut.

If the machinist setting up the manifold in the mill knows what he is doing he can correct the angle while he’s in there.

Hence the clean up cut.
 
Dry fit tight. stick feeler gauges in the passenger side rear corner. Whatever that number is have the machine shop take it off of both sides, but they will need to leave that corner as the last part to get surfaces to fix the angle. Call it an offset cut.
Then stack gaskets to make up the space.
I got in a hurry when my engine was on the dyno.
I had a huge vacuum leak on Super warped tunnel ram from hours of welding after I surfaced it, I found about a .030 gap in the same spot as yours. I will fix it as a mentioned above.
I was able to make the leak go away with right stuff sealer but that was the wrong way lol.

Or maybe the easiest and cheapest option buy another intake
 
This past weekend I was able to get some time on the car. So I was able to clean everything off of the intake and areas on the heads. I set the intake in position and threaded one bolt on each side of the intake to center the intake. The bolt holes appear to almost be spot on with their thread counter parts. I took the thinnest feeler gage I have (.005") and I was not able to insert the end more than about .020" in some areas.

So I believe the angles are okay with only the thickness of the intake gasket needing to come off. I will try to confirm that with the machine shop today and see when he can get me in his schedule.
 
That’s good. Make sure you check under each pair of intake runners
 
I was able to get the intake back from the machine shop and installed. It appeared that everything lined up and sealed up well. I did two cold starts. First one initially after everything was back together., which I knew would be bad due to degreeing the cam shaft so I didnt think that start would be indicative of the changes. got the engine warm, set the base timing and adjusted the idle settings are the carb, shut it down and let it cool down for two days. the second start up it did start to smoke a little and the rpms dropped a bit, but using some people's suggestions from here (thank you), I opened the choke a little more and the idle smoothed out. So it appears not only was there a vacuum leak but the choke also needs work. Unfortenately I wont get time to work on that for a bit. I needed to swap the charger and my truck out before the snow came so I could get some maintenance work done to the truck. So come spring time I will work on the choke and the other carb adjustments.

So just a little more and this car should be good! thanks everyone!
