351 Guru needed on Weiand intake install

[Dirtroadjunkie]

I swapped the intake on my 351 last night and now I'm scared to start it. This morning I double thought a few things. There were less bolts, which the instructions say is normal. The other difference that I can't get over is the coolant passages towards the radiator of the heads. The Weiand has rectangular shaped openings, my heads have L shaped. Instructions said that their manifolds fit the different heads.

This site says that my engine will now fill up with water.

Here's the link to installation instructions.

While installing I thought no big deal just a bigger port, plus its not brain surgery just an intake. It was getting dark and I was a couple beers in. Wish I had taken a better look.

Anyone have any insight to prevent me from pulling the intake to inspect more clearly??

Put water in it and see what happens.

Did you use this gasket?

If I was not using the bolt I would fill and seal the bolt hole

I have never had an issue with this. Kind of interesting used to work in a machine shop building motors and alot of them were 351w never heard anything about this.

Could do what Bax said would should help take your mind off the problem

 

[Dirtroadjunkie]

Yep I used a gasket like that. Fel-Pro. I carved it to match the rectangular manifold ports. May have been better not to carve. I don't see how leaving the gasket material there would have sealed the hole off long term.

 

[Dirtroadjunkie]

Any bulletproof recommendations for sealing that bolt hole? I'm leaning towards Bax's idea.

They're blind holes, don't sweat it, fire it up

That's an unusual gasket. It looks like they made a channel in it to bleed off leaking coolant to keep it out of the intake port.

 

[Dirtroadjunkie]

Too late. Intakes off, holes are sealed, picking up new gaskets in the morning. If there blind holes curse the one that I saw on that link. Better safe than sorry. If there's a hard way to do something it will always be my way.

Well since the intake is off, peep down into the holes in the heads where it bolts to and see for yourself

Thanks guys for the input!!! This site is epic and never lets me down!

I've been running that intake on a 93 351 for 18,000 miles with no problems.
