Swapping a Stock Intake for a new Edelbrock intake on a 454

- I am swapping out my stock 454 intake manifold on my 1971 Chevy truck for a new air gap Edelbrock intake manifold. I previously installed an Atomic MSD efi system on my truck and am dealing with starting problems when it gets hot. This new intake should eliminate the heating problem because of the absence of the exhaust cross over. The change over turn out to be a smooth process with great results.
It's funny how those big blocks run better with the stock cast iron manifold.
Stock seems to always be better but things got so hot it was causing issues. With this manifold, The EFI stays nice and cool. Thanks. Stevo
I love the truck and the 8 track player. I always liked when the player would change in the middle of a song. LOL 😀
Not many know what an 8 track is though. It's a good conversation piece
That is a smart upgrade Steve. I am surprised the throttle body worked that well with the original intake. That job would hard on the knees. I am so happy you could eat off that engine.
I was surprised at the difference it made.
Glad I found your Channel , love the truck , Liked and Subscribed!
Thanks so much for subscribing. Haven't had the truck out much yet, spring just doesn't want to show up here. Stevo
Lots of fun today !!!!
Nice clean truck!
Thanks. Took a lot of work to get it there but it was worth it. Thanks. Stevo
Beautiful. My 69 is not as original as yours. Absolutely love it
I have a 69 as well that I will eventually get to. Going to keep it original with the stock 350. I need a good grocery getter. Stevo
Nice truck!
It is a nice ride. Thanks
Nice video Sir👍🏼
Thanks for watching. Stevo
Hope everything works out! Runs cooler and get better gas mileage!
Its winter so I am not driving it right now but hope to give an update when the numbers come in. Thanks
Subbed for sure!
Nice truck, I'm in New Zealand and have had a few 80's square body Chevys in the past but right now I've got a 95 C1500 5.7TBI ex cab which I just did the intake gaskets on. (what a pain in the ass that was) But also have a 66 Bel Air 2 door post with a 454 with 5 speed TKO 600 manual and what a scary beast she is, a real sleeper with hub caps etc. I'm about to do the intake gaskets on her too which will be so easy compared to the 350TBI. My 454 is honestly the least complicated and most reliable car, cant beat it. Thanks for the video.
I love the ole 454 as well, very easy to work on. Jealous about the two door Bel Air, a definite head turner. May have to easy off the pedal with the fuel prices these days. Stevo
@@stevoj8959 Man the fuel here in New Zealand is at the highest it's ever been, what makes it worse is that our evil government takes about 52% profit from every dollar we spend on gas. The Bel Air is on my channel if you want to see the old girl. Cheers mate for the great videos you do
@@cj8172 Will check it out
@@cj8172 Yep that is one sweet ride. Love how it is so original looking, that's what I go for. Stevo
I still have one 8- Tracker player on the shelf with my small radio collection I agree that the modern intake will be better getting rid of the factory Idea of the EX heat ports...Like the double snorkel air cleaner
I am glad I went factory first because it really shows what an upgrade can add to performance.
DID I HEAR CORRECTLY? Airgap intake reduces vapor lock. Nick Samargis M.A.
It would keep your carb or fuel injection body much cooler. Noticed a big difference especially if you let it sit for a bit. No regrets. Thanks. Stevo
My father had the same pickup with a 292 (6 cylinder). I would set on the steel inner fenders, to change spark plugs.
I do have a 69 as well with a 6 cylinder in it but it is pouched. Would probably get better mileage than a big V8. My dad had a 69 when I was growing up and there were so good memories with that as well. Thanks. Stevo
In all my years working on old farm truck engines like the 454 did i ever use s vacumme or even been that clean yet they were worked hard ever day
Good vid tho
Thanks for viewing. When I was younger i was never that particular and you're right, they never stop. Thanks Stevo
Steve, I've been running a BBC in my '71 Ford F-250 highboy since 1979. A little over a year ago I upgraded to the 700R4/4L60 trans. I love this setup. With 4.11 diff I am going 65 MPH at 1900 RPM.
A 71 highboy is a nice rare truck! Finding the right combo just makes it a fun ride.
@@stevoj8959Finally put this same intake on mine. So far I can say I must have gotten rid of 30 lbs. I have forgotten through the years just how heavy the cast intake is. 😊
@@jedclampett6466 They are definitely lighter. I am running an EFI and it keeps it so much cooler. Thanks for tuning in. Stevo
if you have coolant passages on the back of a intake ,use them .I plumbed them with hoses ,the engine ran cooler ,and I had to enrichen the idle circuit
I will look into that. Thanks for the info
Did your instructions say not to tighten the top holes (#5, 10, 11, and 16) with a torque wrench? I also noticed you haven't drilled relief holes on your thermostat, but you do have the bypass hose installed, I believe. Is that the stock item, or aftermarket? How much re-learning did your fuel injection have to do?
Also, is it small oval peanut port?
Again. Thank you
Change ur fuel lines to the OUT Side of ur frame & insulat ! Yes today's gas boil's at around 95 degrees , so when ur fuel line runs there by the Exhust Vapor lock ! Fuel now day's are made for fuel injection ,
I did that very thing just shortly after I installed it. I have the lines insulated right up to the throttle body and not an issue. The new intake helped keep thing way cooler as well. Thanks for tuning in. Stevo
Anything with a Chevy 454 in it makes me happy. I missed you putting the truck together so is the engine a new one or rebuilt ? Dad had a Chevy 68 with 327. Was a good truck but couldn't keep paint on the dang thing. Thanks for sharing.
454 is smooth and fun to drive. Thanks for watching
Great video,,how did you get the stud torque,I can't get a socket on mine,,same set up I have.
If you had a swivel socket you should be able to get it or just use a wrench. Put the wrench on a fully torqued bolt to get a feel first. This intake really keeps cool. Thanks. Stevo
You should have covered the opening in the intake before you blew the dirt off.
Just curious why you didn't use a phenolic carb spacer. The laminate transfers approximately ten times less heat to the carburetor base resulting in cooler denser fuel/air mixtures. ?
I never thought about using a phenolic spacer but with the set up as I have it now, there is very little heat. I like your suggestion. Thanks Stevo
You need to look into Scotchbright, and Roloc.
I have Scotchbright every where, the only name I will use but I do have some Roloc products but never thought to use them. Some swear by them. Thanks Stevo
What is the part number on the intake? Have a small block 350 with a fitech efi that keeps burning up circuit board that controls injectors every 2 months. Want to use the part number and see if jegs can match it to what I need.
May be the same issue getting too hot front the exhaust flow.
The part number is EDL - 7561. This is for a 454 but they should be able to figure out the right one for you. Good luck and I hope this helps you cure the problem. Stevo J
this helped me alot thanks im 15 years old and just bought my first square. Its a 73 454 how do i buy an intake im confused with the oval or rectangle port on the intake what do i need? or how do i check? thank you gramps
It all depends on the year of the engine. You should have the oval ports. My engine was out of a 75 and it took a 7561 Edelbrock intake. Stevo
Hey Steve just curious how's the truck running with that exhaust crossover blocked on the new intake? Any issues or no worries?
I am not running it in the winter where the cross over would help but in the summer, everything is much cooler and it runs better. Big benefit in my mind. Stevo
Big blocks need to breath, headers with 3" duals will complement the air gap big time.
I have thought about that but with a stock engine the benefit to the cost ratio might not be there. Would sure sound good. Stevo
Actually in stock form you will get 30 hp and almost 50 tq with just adding headers so to me it's a no Brainer to add headers and summit has a good set for 250$ I have a 77 tripple e motorhome I installed air Gap intake and headers and it's night and day!
no demo footage of the starting issues when vehicle at temp ?
Sorry no. The engine would just turn over. With the heat, the unit would read a high fuel pressure and not turn the pump on. Also insulated the lines and it is working good now. Stevo
Did u notice any difference between the 2 intakes like hp or mpg
I found it ran a bit smoother with the Edelbrock intake but as for mpg, I'm not sure it made a difference. The big difference is it kept the throttle body cool and that is what I wanted to achieve. Thanks. Stevo
Mileage when your foots not in it?
I mean round abouts estimate.
Thanks
When I try and be normal, I get around 16 MPG and about 9- 10 when I am pulling my trailer. I have not done an empty long highway cruise yet to see what the best mileage would be. It is hard not to tromp on it though. Thanks. Stevo
what grit sandpaper you recommend
I usually use an 80 grit. Any finer and it just gums up. Thanks for tuning in. Stevo
What intake gasket is that
I just used a stock intake gasket. Stevo
What brand ratchet you using?
That would be a Snap On. I have one that is about 40 years old but my new one is really nice. Thanks for tuning in. Stevo
Is that the same as the 454ss??? Can I use those same parts on the 1990 454ss ???
I believe the intake will be different because of a different year. Other than that it should all work. Your dealer should be able to point you to the right one, there are quite a few. Stevo
