i just pulled a 327 engine and my friend told me that the motor has fuelie heads on it
what are fuelie heads
thanks

iroc22

Fuelie heads are the 461 casting, one of the better castings from the 60's. They were found 61-67 on the higher horsepower 283's and 327's, fitted with either 1.94/1.5 or 2.02/1.6 valve configurations. Their flow numbers are ok, but basically any aftermarket casting will outperform these heads.

They are valuable to someone restoring an old Vette or something; they will not install into one of these cars gracefully at all, because they lack the bolt holes in their ends that is the provision for accessory mounting brackets.

"Fuelie" came from their first being used on engines with the old Rochester mecahnical fuel injection.

Sell them to a Vette owner in Hemmings or something, and get yourself something better that will fit your car.

Look under the valve cover of the heads and get the
head casting number.

You can look them up here.

Just figured I'd add a little more info on the fuelie heads. They did cast a fuelie, or "camelback" head from '69 to about '72 that had the accesory bolt holes in the ends. I think the casting # for those is 292 if I remember right. But I have to agree with the other guys that you'd see better performance from an aftermarket head as their flow numbers are usually a lot higher. In fact, the only fuelie with fairly impressive flow numbers is the 461X casting, which is an extremely scarce find. Another great myth about the fuelie heads is everybody has the impression that they're all 2.02/1.60 valves, when in fact the vast majority of them are 1.94/1.50. A lot of guys also think they're corvette specific, when in fact, you can find them on impalas, chevelles, novas, etc. I also have to agree that you'd probably be better off selling them to someone into the older engines like in Hemmings or on ebay. If you're just building up a mild street/strip type engine though, they work pretty damn good for a stock GM casting. On a third gen, you'd definitely need the ones with the accesory mounting holes for them to be "user friendly".

RB83L69

There are a number of such castings, although the chamber design is different in the ones with bolt holes (they are designed to be able to run on much lower grade fuel). 292 is one casting; other common ones are 041, 492, and 186. However, none of them came from the factory on 327s; by the time they added the bolt holes, the 327 was only used as the low-perf 2-barrel motor.

These are 186s.

The fuelie heads came almost predominately on the 327 engines more than anything else, and I wouldn't consider the ones with the bolt holes low performance heads considering they came on the 350 HP LT1 Z/28 motors in 1970. Besides that, the 327 was discontinued in mid-1969 and replaced by the 307, which was the very definition of a low performance motor!

RB83L69

The ones with bolt holes didn't come on any 327s at all. They came on 350s and 302s, and only the better-performing of the 350s. Only the ones without them came on 327s, and you're right, those were the hottest motors of their day. But by the time the factory invented the accessory bolt hole scheme, the 327 was relegated to the low-perf motor, along with the 307. Anybody that wanted real power in those days got a big block, with certain exceptions such as the Z28.

That set of mine in that pic probably came off of a 69 or 70 Impala, maybe a station wagon; that's what I always used to go looking for when I wanted a set. I've had those and some others like them for 20 years or more now.

There's the RB I know and admire! I misunderstood what you meant about the bolt holes and the 327's. You're right on that.

RB83L69

Yeah, my wording wasn't too clear... sorry

gameover9677

thanks for all of the info on the heads i pulled the motor out of a 1968 Impala i was thinking about putting it in a 1987 camaro z28 just for mild street performance

I have a set of ported 461 heads that I'd part with not to much money. They need guides and seats put in them. I had them on my 350 with a 268xtreme cam and the car ran good. These heads don't have the bolt holes for accesories. However there has been a hole brazed into the passenger side for a late model style alternator. There's a website, can't remember which one, that shows flow numbers of stock GM heads, the 461's aren't to bad I think they flow around 210 on the intake side stock, I could be off though.

a Buddy of mine brant has an 86 firebird with a 327,And 88 Chevy truck 350TBI head's on it .

Edelbrock performer intake and 600CFM 4bbl Edlebrock.
700R4 and 2,73 gear's.....

but he has a cam,And4.11's waiting to go in it..
He Jist low on cash.

He would like to get some Dart Iron eagel head's.
and run a 10.2-10.6:1 C/R.

But i think that might be a bit much for just and Avenue racer.

Only run like 0-50Mph. Unless he's after a stang he'll whined it out.

Me and him have stayed in it racing each other till 120-130Mph......
But with his 4.11's i think he'll be all done at 100-115mph.

so when i was "fuelie heads" it made me think of this Fine beast

327's are good engines, if your gonna put it in a 3rdgen you'll like it. I have a 327 also it came from a 1969 Impala SS, its got the large journal with the stock heads, who says the stockers dont flow? im pushing 400hp & 400tq on them with 10.5cr, stage 3 cam, Hi-Nickle, you can make make the 327 mild or wild.

RB83L69

IIRC there was no such thing as a 69 Impala SS with a 327. In fact, IIRC there was no Impala SS in 69; and in case I'm wrong and there was, it would have had a 396 like every other Chevy SS in 69 except for the base-model Camaro SS which got a 350 (with 186 heads, mind you), not some lame smaller-than-nominal small block. But, memory clouds with time; they say the second thing you lose as you get older is your memory, but I forgot what the first thing they said goes away.

But you're right as far as it goes, you can build the LJ 327 to any level you care to, just like you can any other motor. Only thing is, you'll get beat by about 7% if you build that motor instead of the one you can build out of the same block with stock parts that's got 7% more cubic inches. That's why I quit building 327s back in the 70s when I wanted a small block for some reason (rare at the time), as soon as 350s started becoming readily available. Got tired of getting beat and decided to become a beater instead of a beatee. It's real simple: anything you can do to a 327, you can also do to a 350, for exactly the same $$$ (maybe less nowadays); only difference is, if you do it to a 350, you get 7% more results. It's so trivial and easy to understand that some people seem to be able to overlook it entirely.

SSC

Well reguardless if you have a LG 327 it came from a truck, if you pulled it from a car it wasent put there by GM.

I personally like 327's I just cant afford to build one proper. If this is going to be the platform for this setup Id suggest using your existing heads on your Fbody now unless you find domed pistons sitting under the fulie heads. If its an untouched 327 its going to need hardend valves anyway to run unleaded fuel.

The large-journal 327 was first available in the 1968 model year and lasted into the 1969 model year. The 350 became the 327's replacement within the 1969 model-year in the big cars. The 350 (and the 307) had replaced the 327 at the start of the '69 model-year in the other car lines.

I would venture to say there were probably several hundred thousand large-journal 327s built those two years and the far majority were in the full-sized cars.

Most of the 327 engines with double-hump heads that I bought (in the late '70s and early '80s) came out of the '68 large cars. As a side note, the most I gave for a COMPLETE 327 was $50. Of course, I yanked the heads and sold them for anywhere from $75 to $100 and then pretty well give away the short-block.

The large-journal 327s were also available in the 1968 model-year Camaros, Novas, Chevelles, and Corvettes.

The 1969 SS Impala was a 427 big-block (390 hp) equipped car. I thought I remembered a more powerful version but my Chevy Super Sports book says otherwise.

I might be throwing out incorrect info as well, but if I am not mistaken, in 1969 the Impala SS came with only the 427 (in 390hp or 425hp flavours) which would have included power disc brakes, standard TH400, upgraded suspension and red stripe tires. The only 327 I know of for the Impalas/Biscaynes/Bel Airs/Caprices was the low compression, low horsepower 2bbl 327; which was base in the Caprice and an option over the straight six in the other three.

My 68 large journal came out of a 68 impala. It was a 250hp 4 barrel quadrajet motor, without fuelie heads. Mine had 1.72 intake valves even. The entire history of this car was known, neighbor bought it new and dad bought it from him. So I know this wasnt swapped in.

Good stuff 327's are awsome engine you beat'em never change the oil they'll still live 120,000miles.

The old 327 i used to run had 278,600miles by the time it started knocking......

but i tuned it up once year and changed oil oil Filter every 1,000miles and oil every 3,000 miles i ran AMSoil 20w-50....

Best Runing c-50 chevy I ever had.......

So i Rebuilt the beast did a few up grade's and now it will pull 6ton's of sand ,gravle dirt,witch ever and run 67MPH all day long.
Now it's a JSM/M&R truck so it get's AMSOIL sae60W and filter changed every 2,000 miles oil every 4,000miles like all my other gas engine truck's.

Jms and Iroc22 are both dead on with the information they gave on the old 327's. There's obviously a few guys on this site that still know their "old school" stuff! I couldn't have put it better myself. I also agree with RB that it makes more sense to build up a 350 instead if you're in the position to be choosy. I know a local guy that owns a fire engine red 69 427 SS Impala. One heck of a formidable machine! Of course if he dropped that same engine in a lighter Camaro or Nova, it'd be incredible. As the old saying goes, "there's no replacement for displacement"! Oh yeah, I forgot to mention, the 69 Camaro SS350 motor got the 441 casting heads with the accessory bolt holes.

I bought a whole running driving 68 Implala 4-dr. once for $50, took the heads after the hood flew up one day while driving down the freeway (you ought to see the people behind you on the road scatter when that happens!!!!), and still got $35 when I hauled it to the crusher.... Of course, it was a 68 full-size, so the heads didn't have the accessory bolt holes, but at the time there were still lots of cars around that you could use them on, so I still made some money.

91 GTA Ramair2

having the hood fly is an exsiting ride ain't it ........

SSC

I dunno, I pulled my one SJ 327 from a 68 impala 2dr 2bbl or 1-1/2 whatever they called it and it was the original owners only engine. The rest of my 327 stash came from trucks. Ive never seen a LJ in any car, I could be wrong but I just never seen one in a car that hasent gotten an engine swaped out.

iroc22

Well, my Dad has a LJ 327 in his 1968 Chevy II/Nova, I believe it is the 4bbl 275hp which would have been the last of the "performance" 327's (I believe there was also a 325hp version available in 68 as well). He bought it 15 years ago from the original owner who left the car 100% bone stock. My Dad rebuilt the 327 (no overbore) and it was definitely a LJ block. Custom interior option, shifter console, bucket seats, it's a nice little car.

chevymad

Wonder if maybe early 68s got the last of the sj motors. My LJ even has the same casting #s as early 350s. And both it and the heads have the right date codes.

GM has Done alot of goofy stuff "acident's" if you will there is on average 3 car's a year that get Engine's they shouldn't......

Some of the B4c's got 350TBI's instead of 350TPI's mistake?? I would think so....I think there is 3 or 4 registerd with a 350TBI in them???

then there's My car with a 350TBI...........Insane........

But Yeah is Totally Possable........
It did come in there But it " shouldnt " have............

I've Found put with GM what " should" be isn't alway's the case there is 3-5 cars/trucks that are the xseption to the Rule......
Well.......any who there's my 2 cent's worth........

you Got one great Enjoy It .......... Need part's Find out what it's most comon in then order the part's you need for that simple........


Anywho Good luck have to care Keep the rubber side downand keep it between the ditches.............
