Subscribe to watch Mike finish this engine build and re-install it into his 1969 Pontiac GTO Restomod, in his home garage! If he can do this at home, so can you! "How to install an Intake Manifold", is Part 19 of this Pontiac 400/455 rebuild, but can be applied to all motor types.

Thanks for your videos! I have been rebuilding the 389 in my 62 Bonneville and your videos have been a big help in the process.

Very helpful, first and probably last Pontiac build, thanks Monty!

[richardalvarez]

Thanks for the video. I’m about to install my manifold and this video helped.

[mcbridjw]

Thanks for these videos, they have been very helpful for me. I have a 72 lemans and wiped out a lobe on the flat tappet cam, so i'm in a similar position. Just broke in my new cam today.

Thankyou for not playing any stupid techno music

[justinsharratt]

another good video I am a few steps ahead of you now lol last weekend finally got the 455 in and she runs like a top. I also separated my water crossover from the intake as well. Keep it up buddy can't wait for you to get it back in the car and enjoy it weather is getting nice around here.

[davidwhitman]

Thanks! This helped me a lot installing mine. Do you have any warm up issues without the exhaust crossover?

[kenwitzell]

Monty, have you ever considered seperating the water crossover from the intake, I did this with my stock intake and have now performed the mod on my Performer RPM. This will allow you to pull the intake without draining the rad. Just a thought!

[gypsynomad]

Hello Monty great video iam working on my 68 Tempest I had a quick question where do you find the gasket the donut o ring for intake manifold just wondering

[BrokePremiere]

Niceeee hook!!! I love it. I’m finally figuring out how to do mine. I can’t wait to watch more! Also a heads up if you download Audacity and use “noise reduction” it’ll clear up the background noise it should help with some of that reverb or echo in the mic. Well I hope that helps! Looks awesome! I hope to colab in the future!

Thank you very much for such a detailed video. I am about to replace the intake manifold gaskets on our 69 GTO. We have a 0.03 over 400 with 068 cam and #62 heads. My dad decided to use The Parts Place reproduction Ram Air IV aluminum intake manifold as he loved the way they look. I am planning to block the exhaust crossover as it is leaking now and the noise is horrible. Per your video I plan to use black RTV for the water jacket and will buy the Locktite Stick you use as well. I read to use copper RTV for the exhaust crossover as well. My question to you is what brand of anti-seize do you recommend? I won't need it for the bolts into my heads, but I will for the water pump bolt into the manifold. Also, you state to torque the manifold bolts to 40ft-lbs, but I read to use 25ft-lbs for aluminum manifolds. Which torque would you recommend for my application?

[vincentanatriello]

There is a hole right in the middle of the heads that the gasket covers up. What is that hole for & why is it covered up?

[tysonewart]

In regards to forming the gaskets for right fit and painting.
I have a 389 tripower with cast iron heads. Do you HAVE to paint the intake mounting surface where there is no gasket? And why?

[robertspadaro]

These videos have been so helpful when it comes to working on my Poncho! Thank you.

I have a real quick question pertaining to the intake-to-timing cover o-ring...

Where exactly is the RTV applied? All around the o-ring itself, or just along the machined mating surfaces? ... ...Or both? Lol

I haven't reached the point of reinstalling my stock intake yet, but I'm picturing the o-ring not staying in place unless there is some RTV around it but you would know better than I do.

[frekkledipped]

why do you put RTV around the water gasket, I mean did someone tell you to or is it just something you want to do?

[therockandrollcreeps]

i thought you worked at butler performance

[chrisgleeson]

Do you trust that lift plate on the intake??

[Ayden-wtxi]

Hey fast montey. I have a 1975 350 Firebird esprit, I recently took off the original intake and put on a old edelbrock aluminum intake on. I went to go start it up and now it smokes a TON of white smoke. Water looks like it is on the dipstick…. Any clue what I messed up? TIA

[sTransAm]

What intake and valley plate should or could I use I have a Pontiac 400 in a Trans-am ? Also does valley plate come with intake when purchased ? Thanks.

[davecalvo]

Hey Monty, excellent content here. I'm about to replace an Edelbrock manifold with a stock spread bore on my 1968 400, my question is would you recommend porting and some polishing of the stock manifold before I install it or don't even bother? Also, where do I source that little o ring gasket for the water jacket on the front of the manifold? please advise and thanx!
