olds 303 or merc flatty

cant figure out if i wanna run a 303 olds or a merc flatty in my 31 sedan what you guys think???

 

depends on the build era you desire... i say go late 50's with the olds, be something a little different

 

thanks trav.....the plan orig****ly was mid fifties with the olds.. but to do it period right have to channel and do lots of chrome...thinkin of runnin a duece frame so not gonna channel...plus not into chrome...so thats the problam think the 303 is a cool motor but the late forties era is more what im into so thats why im thinkin flatty

 

either style is bad***... just dont mix and match the two! goodluck with the build

 

thanks for the info deff wont mix and match haha

 

the 303 was first offered in 1949

I'm building an early fifties style hot rod with an Olds and it will have almost no chrome

 

As far as the early OHV V8s go, the Olds is the easiest to find speed equipment for. Even a mild 303 will put out 200 hp, which puts it into full race flathead territory.

 

ya paul your right doesnt have to have chrome...love to see some pics of your build....what kind of car ya building?

 

ya the olds will deff put out the hp real nice....the flatty would be more for the style than the speed...hahaha this is why its a hard choice...love the input guys thanks keep it comin

 

i agree... doesnt need chrome to be cool

 

Either choice looks cool.


Here is a 32 from a show with Olds motor, not much chrome. Just aluminum intake and valve covers and no chromed ch***is parts. Looks like an early 50s style to me..maybe mid 50s.

 

The 303 would be my choice and you can build an early to mid '50s rod with one. The rodders started using them as soon as they could get their hands on one. It wasn't uncommon or isn't uncommon for the rodders to be using the newest and sestes as soon as it hits the streets.

Anyway given my choices I would choose the valve in head.

 

put together a mid '50s style '27 T RPU with a '50 303 a few years ago,
been driving it while slowly pecking away at a '60s Style '57 371 powered '30 A Coupe
and an early '50s style '56 324 powered '27 T Roadster.

pictures can be seen in my albums

 

Here is a pic from hamb. Might be one of Tony's.

Not much shiny stuff but it looks great like this. Maybe add multiple carbs if you can, like 2x2 or 3x2, or even a single carb would be fine with the Olds aircleaner with the side scoops. Some people call them batwing air cleaners.

 

right could have a 40s era rod with early 50s motor thanks for the input

 

i have a edmunds intake with 2 carter backdraft carbs

 

great pic

 

nice pics paul cars look great

 

Either is cool but it may come down to what is available at the time. The Olds doesn't need a lot of bling to make it cool and chrome and cast aluminum pieces can always come later after it is up and running too just like guys did back in the 50's.

In the end the cost of either will be so close that it isn't really a cost issue.

 

Olds all the way!

 

I am not familiar with Carter, but Rochester made the backdraft for the Olds early 303's.

There were two different 303 Edmunds 2x2 intakes. The early one is a low riser with open webs between the runners and you can see the valley pan. The later one is a closed web with higher rise. The higher carbs leaves more room under the Edmunds back draft air cleaner to be able to get plug wires into the dist cap without using carb spacers.

 

I see the Carter backdrafts on '49s more than '50s, but I think that they were available both years. They had an oval air intake opening, as opposed to the round opening on the Rochester AAs. Edmunds made air cleaners for the oval carbs, but they're about as easy to find as $1.00/gal gas.

 

That's a V-6, just look at the headers,{ sorry no goofy head icons for being this stupid }

 

Both are bad *** motors. I'd have to flip a coin.

 

use the olds flattys are nice but olds is way cool to and sound good

 

Really ..I hope your joking? Look closer my freind.....That Rockets got 8 plugs

Just like a Flatty only 3 port exits,centers on an early Olds merge together into larger one

Yea right, V6 Rocket

Here is a better pic of the same V6. Count the plug wires...you can count, can't you?


There also is no icon for being an ***hat. Go back to your crate motor world.

You probably been looking at too many sbc's with with the tacky fake Olds valve covers.

 

Not trying to piss anybody off, but that's what happened to me the first time a stopped at a gas station with my 425 Olds: Guy comes up and tells my that my V6 looked really nice and clean! He was a nice guy though, so I didn't tell him he was wrong.

 

The center exhaust ports were called a "siamese" style; joined at the hip, er....head, you might say..

 

Olds, if it were my car....
