RA V parts are literally impossible to find anywhere! However, if money is no object I suppose a good machine shop could make the parts from scratch if someone really needed and wanted something super extra special!

This guy is an amateur

I don't know what to think about something going through the int. Port.

Pontiac porn 😍

Not a roller cam ? Right ?

That would be badass in a 68 firebird!

Nice work, where are you located ?

Just to think of what could have been had they ever made production.

I would've put a set of 3 &1/2" unbaffled 60" straights onto the header collectors. They sound amazing.

Bro, that thing is no joke ! Must have cost alot of money. Has to make at least 650-700 hp

It needs equal length 180* headers and ITBs. Any flywheel is too much flywheel. It needs more cam duration. It needs more valve spring. It needs to turn 11k RPMs. And the vehicle it’s going into is too heavy.

Those heads must be the later 69 722’s. The early 1969 Ram Air 4’s had 614 heads right? Then they made a couple changes to the heads and they became 722’s.

I am building a mild Pontiac 455. I am thinking of going with the 067 cam, as I am afraid that the 068 cam may sound too radical. Any thoughts on the 067 cam in a 455? Using 1973 4X-3H heads shaved .016. I was going for 6X-4 heads, but one magnafluxed showing a crack!

i have used 1.65 rockers 0.6o push rods and rhoads lifters which are variable duration and got good performance low mid range and great top end if you can deal with the solid lifter sound at idle from a hydralic lifter pontiac pete

I jave one of them old dwell meters , its a cool little tool. She aounds like a B-29 and thats a good thing. Wicked.

Get a decent welder OR dont show your welds next time. -just sayin

16 heads are very good heads💪🏾

Pontiacs biggest problem was heads not meant for performance. Ram Air heads difficult to get but now aftermarket heads available.

Im guessing 650 hp min?

Imagine what the history of racing would have been if GM wouldn’t have pulled funding from Pontiac (at Chevy’s insistence I’d bet) and Pontiac would have been able to refine the Ram Air V heads for standard production use.

Spotsylvania 😂 I've seen a lot of Spots builds 389s 400hundreds and 455s and everyone was a top notch build. Also he built a 455 ram air 5v in a 69 trans am i saw on video which i think was a two speed power glide and when it hit second gear it almost flipped on its roof in a split second. I don't know how he saved it but he did with.a lot of damage to the front end when it came down, even this engine he built for the g.t.o. convertible should really think about putting wheelie bars on it. And if it were my car id probably would have the ones that come straight down from the bumper for the street so Johnny law don't mess with him. Ps great video, i have a 1970 g.t.o. convertible im doing right now and i have a 72 block so you'll be hearing from me soon thanks Spots performance

did Stevie Wonder weld those headers ? i wouln't have shown that .. what oil pump and pressure ?

Very cool. Who does your machine work? Have you ever sleeved a Pontiac block?

The only thing here that is Pontiac is the Block, water pump & cover!

original 4 bolt mains ?

Are those #96 d-port 400 heads? If so those are some of the best heads you can run on a 455 combo.

Nice build. Thanks for sharing the process.

Love the old man admiring the motor at the end. He reminds me of my great uncle Tony

Dude that really is a nice piece. All the little things make all the difference on the big end time consuming

And yes I remember in 78 him working on a Ram air V in his shop in Bklyn.

The older gentleman in the video is probably around the age Nunzzi would be today looking at one of his creations come to life.

Interesting. Ford. 302/ 427 Tunnel port. Design set up for a Pontiac

Add the valve cover 'Ram Air V' label and done!

What was the LSA on that, 112?

That's going to be a really nice motor not many people can have one of those not a Ram air five super cool thanks for doing the video keeps me inspired I I used to own a 69 Firebird400 4 speed convertible oh stupid to sell it that was in the late 70s what did I know have a great day

Installing pipe plugs should never be a highlight included in an engine build video. Along with boring monotone narration.

That would go great in my 68 firebird coupe

A lot comments on here that think they know Pontiacs

Amazing job on the video probably one of the best I've seen. You just created the holy Grail again.. could you tell me what main caps you used? Did you keep the front and rear caps stock?

Can I have it for my Firebird? 😊

Junk heads and shitty build. Believe me i know this guy. The engine did not last long. Go to butler for all your pomtiac builds and you wont be disappointed.

Very cool 😎

Just like 427 tunnel port Ford head with push rod tube through the middle of the intake port.

nice!

This may be a dumb question as I’m not up to speed on Pontiac engines but why doesn’t anyone reproduce the RA-5 heads ?? From what little I know of Pontiac the non ra-5 heads have the #3,5 exhaust ports and the 4-6 exhaust ports too close together causing too much heat build up ….. just from what I can see of the RA-5 it looks like it would be a much better head design or am I completely stupid cause I’ve been around ferds too long ?

Thank you for sharing, I would love to biuld a Ram Air 5. I have a few ponchos and 455 WC code block

The first pictures of the test fitting of the heads are not Ram Air V heads. They are Ram Air IV heads. The 2 center ports are next to each other. Ram Air IV.

As much as I can appreciate the ram air V, how much better is it over the RA IV?

PONTIAC THE BEST I HAD 18 IN MY DAY💪

is that an aluminum poncho v8 block
