455 Olds into 80 Catalina

No expert here, don't know the weight of it but had a 1979 Nova with a 455 Buick engine from a 1971 Riviera and it was a blast to drive with all that torque.

 

some guys here had one in a chevette

 

I think if we read carefully, it says the "block" weighs 25 more lbs than a SBC. It doesn't say a complete engine weighs 25 lbs more.

 

All the complete engine's peripherals should way the same, since they are the same. The Buick 455 didn't have to beef up the bottom end so much, because it was the only oversquare type out of the 3 which meant lower piston speeds. Even though, the Buick had the largest pistons of the 3 455s, this is still only additional aluminum, ring steel and maybe wristpin if longer.
Aluminum heads would be going over the top, depending on spare time and finances: http://www.carcraft.com/techarticles/ccrp_0907_buick_455_cylinder_heads/viewall.html
But, using headers and an aluminum intake should put the Buick on a diet which should get the weight down to at least that of the Chevy's

 

Sure as hell better find a way to beef up the oiling system, very prone to failure. I have stage 1 heads in my basement and could of put them on my LOW mile engine and a cam and bingo I have a stage1 and yes the engine they came off of SCREAMED! Guess what I went with the old poncho and don't regret a thing!

 

wonder why they used olds' and BBC's in boats but not pontiacs or buicks,..
mebbe the boats already had anchors,..

 

I had a buick 4 bolt big block in the engine pile a LONG LONG time ago Never looked it up as it had frozen and broken beyond repair, It was in a boat. I have never seen another one with the 4 bolt mains

I had seen that years ago so your point is?

 

he think he's trying to tell you that the "broken" engine you had might have been worth fixing???? (Not sure though)

 

I thought about that honestly I did. it had a marine tag right on it>( this blew my mind) I had never seen one before and also this was WAYY before the internet.( in our parts anyhow lol) But I have to tell you it was WASTED broken junk. basically broken in half both sides broken out lifter valleys broken out and I think the cyl were even broken. mind you guys this was probably 20-30 years ago in the scrap engine pile at the junkyard I worked at. But I know what it was.

 

Obviously you don't know much about an Olds motor....lol

 

Really ya think? I've owned PLENTY of em and driven them daily over my 30+ years of driving, and know others that have owned some damn beefy ones.

I know they run hot even stock, they always start hard because of it and they don't take heat well. And power wise yes i'll take the poncho ANY DAY!


That's plenty enough for me...... lol

 

That statement actually shows how little you know about them.

 

ROFLMMFAO! Dude your classic! Drove and derbied(without the olds engine cause they're duds) probably in the 100 plus area?

Personally road drove around 10 over the years all of em had the same quirks. I will say the junk heat killed 350 I replaced in my cutlass with the 330 ran like a raped ape, but it STILL had the hard crank problem when you drove it and it sat and restarted warm. And no it wasn't the timing! No it wasn't the starter, and NO it wasn't the rad. I worked in the salvage yard the whole time and always ALWAYS had access to practically NEW parts. Unless you were back in the 60's maybe 1970 yes they ran very very well but still had that heat quirk. as for the newer ones in the 74-76? underpowered dud's compared to a buick or poncho.

Not going to sit and argue about something I have ROAD TESTED myself!

Thanks
