How well does a big block 454 fit in a g-body Malibu? Header fitment etc.

[@user-lu2vu5go9c]

Ps I wish my headers on a small block fit that well. You do excellent work. ❤

[@Farm10customs]

Zac actually got pretty lucky finding a set of headers that fit that well. Thank you for the kind words my friend.

[@user-lu2vu5go9c]

Gotta a 78 myself. You should've painted the motor chevy orange. Other than that great video. ❤

[@Farm10customs]

Thats awesome, the g-body’s are cool. We painted it blue because wanted it to appear as if this car actually came with a big block. Just for fun. Thank you for watching.

[@Scrabnor-Mudflap]

Guys! I built same car! Glad to see it! ('80 malibu w/468, Super Comp headers, Ford 9", Richmond 5 spd, yada, yada...) Had to overcome lotsa obstacles but it all worked. Great to see someone else w/same idea!

[@Farm10customs]

That’s awesome. It sounds cool, would love to see it. It actually surprised me how well the big block fits in there. This is the starting point, getting it on the road. He’s definitely going to do more upgrades later, $$$ when he can. Thanks for your support.

[@SaneCayne]

Looks good. You guys sure get a lot done in a short amount of time.

[@Farm10customs]

Thanks buddy. Its been a long time coming. He’s been planning this for a few years. Having fun doing this too.

Awesome I always loved to put a big block in my Malibu ❤❤❤❤ I was thinking about LS but the big block looks more originality

Love the build guys It would've been nice ya would've showed were the mount gets mounted on the chasis

[@Farm10customs]

Thanks. I really didn’t specifically mention the motor mounts but that big monster actually fit directly into place on the original mounts. But because of header fitment we had to modify the left block mount. That was the only modification we had to make. Even the transmission sat into place. It was just that simple, amazingly. I’m willing to answer any questions about it, please feel free to ask. Thank you for watching and for your comment

@@albertorodriguez6661 Yes sir, it bolted directly onto the factory 305 v8 motor mounts.

[@Farm10customs]

@@albertorodriguez6661 A big block Monte Carlo, that’s very cool. Those big blocks belong in the G bodies. I see the concern with the motor mounts. You could measure from back of the block to the motor mount to see if the v6 and v8 are the same distances. I think they might be the same. Not totally sure though. You could always do a test fit. Best of luck

Was wondering how this has been coming along up to now? Have an '87 MCSS Aerocoupe, since '91, and have been itching to drop in a GMPP crate big block

[@Farm10customs]

Well, Zac has been working on it when he has time. He’s currently upgrading the fuel system and replacing the brakes. And wants to replace the steering column before he drives it very much. Not much to really report yet. We will definitely have a video on it down the road. I love those g body montes. Thats awesome that you’ve had it for so long, it definitely would be cool with the BB in it. Stay tuned my friend and thanks for watching

@@larrypineault5302 I really wish I could give you an actual part number. My boy Zac picked them up from Amazon about 6 months before we did the work, but when I asked him for the info for them, the listing was gone.

[@Mr.Frost181]

So exactly how much horsepower does a stock 454 make since they putting it in there bone stock with no upgrades

[@Farm10customs]

They say a stock 454 has at the low end about 230 hp with 385 lb-ft of torque and can go up from there. This engine is basically a stock engine, aside from adding a mild camshaft, intake and carburetor, and headers. With these upgrades it could add at least somewhere between 50-100 horsepower, I’m just guesstimating. No dyno testing here. Hopefully this answers the question. Thank you my friend.

[@jarrettwoodward2585]

@Farm10customs is being very modest here. My 1970 396 bored to a 406 (6.6l) dynos at 430 horsepower at 5500 rpm (can run this engine at 7000) mind you. A 454 is bigger. And to Farm10customs. Nice job! My big block likes to flex a lot even with new mounts. You will want good room for flex. In my case a set of drag headers fixed both room issues.

[@dopie5817]

What oil pan did you guys use? Im just about to do an BBC swap in my 86 cutlass. Any help on everything you guys did would be sweet! This video was great. First engine swap ive done and im on a time crunch aha

[@Farm10customs]

That’s going to be so cool, Big block cutlass. We just used the stock oil pan. It was an easy swap. If we dropped in the completely stock engine with OE intake and exhaust manifolds, it would have been a simple drop in. Enjoy your project and good luck.

[@kuro-textingstorys2823]

im confused about the motor mounts did you use small block mounts or something else because online i cant find a specified mount for this conversion

[@Farm10customs]

Yes, They are the original style mounts that came in that car with the small block. They are also the same mounts that were on the big block too. Pretty handy and very versatile. Both engines sit in the same position. This is really just a drop in, aside from the accessories. I hope this helps you my friend.

What are those headers?

[@Farm10customs]

@@terranceboyer633 Zac had purchased them off of Amazon at least 6 months before we did that work. I had asked him for the listing info and the listing wasn’t available anymore. He thinks it said “fits BBC shorty. We think they are the same as early camero. He really can’t remember what the listing said. And maybe he just got lucky. Obviously they need a little modification but that’s fairly common. I wish I could tell you more. Good luck my friend

[@keystoneangler3217]

Header brand?

[@Farm10customs]

Sorry my friend. Zac got them off of Amazon about a year before we did the work and the listing was pulled by the time we got to the Malibu. All he could remember was “fits big block, short header.” We kinda think they could Camaro or something like that. He really couldn’t remember anything more about them.

Wow man, that’s a big project and sounds awesome. I know , those headers for big block g-body applications are way too expensive. we knew there was something close to fitting and Zac took a gamble that worked out great, better than I expected. It definitely saved a ton of money. Just curious, How well do those headers you have fit your Monty?

Hey there, Believe it or not we used the original motor mounts. It fit perfectly into the engine bay on those mounts.

Hi...which headers did you use?

Hi, I wish I could give you a part number but I can’t. Zac ordered these off Amazon at least 6 months before we installed them. I asked him for the information on them and the listing had ended, so he couldn’t get the information. All the info he had was what he had stated at the end of the video. He didn’t think he had gotten it specific… actually he just got lucky, I think. They appear to be a short early camero but I’m not certain. I tried to share what little information we had. I can definitely ask him again….

How does it make the water pump turn backwards? The belt is going to turn the pump in the direction that the engine turns. I've never heard of that before my buddy has one on a small block and it works just like a stock v belt set up. But it's got the ribbed belts.
