i recently purchased a 70 buick skylark with a straight 6. my dilema is in regards to what v8 i should drop in. i can get both pretty cheap, but whats the pro's & con's? seem's to me buick 350 parts are a little harder to find and might not make as much power is the chevy. am i off base? anyone else do this chevy in a buick swap and can offer some advice? this isn't going to be a numbers matching car...so i can't see why not to go with the chevy, but i also would like to see it "all buick"

anyone?

You are right with the parts pricing availability.

It just dissappointing to see another chevy in a Buick. People ususally do it because it's cheap. If you are really interested in building power put a Buick 455 in it, they were know as "Hemi eaters".

Remember, no matter what some guy with a 350 (VW) chevy says, you can't beat the cubes!

and might not make as much power is the chevy.

yeah, there's very little in the way of aftermarket parts for the Buick. www.TAPerformance.com is working on aluminum heads and a single plane intake but until they get those out ~500hp will be the most you can practically expect to make AND it will take a bunch of money to get there.

there are a bunch of Buick guys down on Long Island. you ought to see if you can find some of the regular cruises and car meets.

When you talk about power , on the street its called TORQ. And thats what Buicks are famous for. You dont have to build a Buick up much because they have plenty of that. A 455 with alum. intake and some headers weigh about the same as a chevy small block, and Skylark,s came with them in the GS.

i'd rather keep it a small block...this is going to be a nice turn key cruiser/ driver. i have had big blocks before and there is no substitute, but its not in the cards for this car. plus i would like to try to put a 700 r-4 trnas behind it for e 4 speed auto instead of a 3 speed. i think it would make the skylark a better driver. i was told the 700 r-4 would not bolt up to a buick 350. any truth to that?

the 700r4 was only ever available with the chevy bell housing. you can still get an adapter plate if you want it to bolt up to a BOPC block but it's just one more thing.

i've heard tell that all of the 200r4 trannies have dual pattern bells on them. you have something against the 200?

see this thread for the different bell housings:

i heard the 700 r-4 was a better trans..thats about all

bob k. mando

for a stock trans, yeah, it is a little better. but 200r4's can be built to handle a BBB.

on the other hand, a SBB isn't going to have the neck breaking torque of a BBB and you're putting it in a mid-size car not a full size car.

if you don't spend a whole lot of time doing burnouts or drag racing it should do fine.

My first hot rod was a chevy powered Model A Ford., It was a stock 56' 265 incher. It garnered lots of attention becuz it was the new kid on the block. It was a fresh new design, and bolted in the Model A.Chevy,s are good engines, and very popular. Your delimma is chosing between Buick and Chevy power. Seems you really like the Chevy better and it is a good engine, and likewise the Buick is a good engine, and the parts are available. It will be a matter of your choice. All I can say is that if you run a stock well tuned BBBuick in your Skylark,you will have an engine that will develop over 500 pounds of torque all the way from start to 5 grand, and will cruise smoothly all day long, You wont need a 700r4, because that big block Buick doesnt care what transmission you have, you will have trouble keeping it from smoking the skins anyway,and wont be just another chevy powered car on cruise night. A Skylark with a Chevy is just a chevelle with Buick badges.

If I chose a Chevy motor over a Buick one it would be for one reason only,Buicks oiling system was and still is a horrible idea.I cannot believe they put the oil pump in the front timing cover and not even in the pan sump.Atleast the morons at Ford put the pump in the pan but they still failed faithfully at around 100,000 miles.I personally would not at this time anyway put a Chevy in my 65 Lark but they are a more dependable motor for sure and parts are really cheap and aftermarket stuff is available.....I am and always have been all my life a Buick owner but that oil pump thing burns me..........Otherwise I love em

Alright, My first post! Well I'll start off by saying I have a 72 skylark with a 455. Now as far as I am concerned I think puting a motor in a car that is a different manufacturer is wrong. If its a ford, than it should have a ford motor, etc...Just like the other guy said, street power = torque and we all know none matched the torque that the buick motors put out. In one of my books there is a very good quote when talking about the buick 455...." The 455 has enough torque to spin the earth off it's axis" Enough said I think?

pfffft. you just don't know how to mod it right. shim your pressure relief spring and you can develop enough pressure to blow the oil filter off of the fitting.

drill out a couple of oil passages and your block will be good for multiple hundreds of thousands of miles.

Could you elaborate on these mods. I am beginning a restoration on my 69 skylark 350 which will include an engine rebuild and would like to incorporate such mods which will improve the engine. Thanks, Tony

!st. the Buick 350 is lighter than the sbc. 2nd. Bill Mahoney in Long Island proved a SBB can make over 1000HP & survive. How much more HP & Torque you need for the street??? A 200r4 will hold up fine. A 350 SBB does not have the oiling problems as the 455 BBB because of the smaller crankshaft size. Then you won't have the normal jelly bean everyone else has. I look at Chevy's like this. No matter what you do to one someone has already done it. I, as well as many others, are really tired of seeing the 700 in everything, 350/350. I know it's cheap & parts are much more readily available but the satisfaction of doing something different has always appealed to me. Then theres the parts serving, like finding GOLD.
Just my thoughts.

I have the350 in my skylark it's a nice cruiser,it has excellent sound on the exhaust i put the flowmaster american thunder system on it with hooker super comp headers.If you're worried about oil prssure put a oil gauge on it did all three gauges to keep an eye on things.I don't trust idiot lites.

sorry abranz, i missed that you had asked that question. hope you still find this helpful:

the 455 mods don't translate directly to a 350, but it will give you something to think about:

SBC's are cheap, there's no denying that.

how does that old saying go, "you get what you pay for"? :waving:

Did I tell you I'm working on both rite now.

why bother building a Chevy when you can buy a brand new fresh from GMPP 350hp crate motor, complete less the carb, for ~$3500 (https://store.gmperformanceparts.com/store/SelectProd.do?prodId=7759&redir=true&manufacturer=GM&category=Engines&name=CT350%20Crate%20Engine&model=%3C%21--88958602--%3E)?





Cheap and fast and I can get ever thing off craigslist.

that's what ~45 years of free aftermarket racing development and R&D will get GM. Buick has never had any of that. until.....




But with a Buick 350 there is nothing you can pay to make as good as a cheap as hell chevy build

a - there have already been NA Buick 350's over 500hp and there was a turbo stock block over 1000. cheap, no. can an SBB compete with an SBC? you might be surprised. especially when you factor in that the SBB package weighs 150lbs less than the SBC. the weight doesn't matter so much on the drag strip but it's really hard to hide how nose heavy an SBC car is in comparison once you have to start turning.


b - www.TAPerformance.com hopes to have aluminum heads and a single plane intake in production for the Buick 350 within the next year or so. that "ease of build" Chevy advantage could get a whole bunch smaller in the next couple of years.

heh.

weren't you the one who said "LET THE FLAME WAR BEGIN"? i haven't even been trying to insult you. i guess you forget to zip up your Flame Suit? :beers:

i won't debate that hi-po SBC's are cheap and common place. you can thank circle track racers like me for most of the development that went into that.

i'm just pointing out that the Buicks aren't necessarily at as big of a performance disadvantage as you think. and they're almost always torquier than an SBC which is more useful on the street.




we are very limited on cash!

which goes back to me asking why you're building your own SBC when you can have a brand new one with a factory warranty for a very reasonable price. that "602" motor i linked in my previous post is another one of those circle track developments i'm talking about.

unless you're using a bunch of parts that you've got sitting around your garage i don't know how you can seriously expect to beat that price.

if you have an engine builder put a motor like that GMPP together you'll be looking at close to 6 grand. i can find it for $3500.
