427/425 Biscayne?
 

What are the odds this is a real one? Were they available in '67? The ad doesn't SAY it's original, but its got that all important "rare" word in there.

Re: 427/425 Biscayne?
 

That car has been on there before. Going from memory, I think "Chevrolet by the Numbers" says something like 12 engines built but no record of installation.

Hey Rick, help me out here!

A recent discussion regarding this issue.
https://www.yenko.net/ubbthreads/show...true#Post19807
I still have never come across a documented '67 425 hp which is a shame as it would make for a VERY neat car. I refuse to believe some dealers didn't install these as well and go racing.

P.S. can someone inform me how to post a link but shorten the address and make it look like "previous discussion" innstead of that long link. [img]/ubbthreads/images/icons/blush.gif[/img]

Thank you gentleman

Re: 427/425 Biscayne?
 

From what I read, Chevy got nervous about handing out the HP in 1967. One late 1966 magazine article said that the 375 HP 396 was not available in the 67 Chevelle and the BB was not available in the 67 Camaro. Chevy changed their mind and made the 375 HP Camaro and Chevelle but info was not on some of the 1967 dealer listings. There may have been some 425 Passenger cars that escaped from the factory but it would be a small number.

Re: 427/425 Biscayne?
 

This particular one looks to have a ten bolt rear, according to the picture on eBay (see attachment).
I don't know much about big cars, but that's not very likely is it?

Re: 427/425 Biscayne?
 

Anyone remember the red/red 66 four door Biscayne that ran in the Supercar Showdown years ago?I think it was claimed to be a orig 427 4 speed.It was out of Lancaster Ohio.I used to have it on video.....real deal?

Steve

Re: 427/425 Biscayne?
 

Red 4 door biscayne was the real deal. I saw an article on this car in the 80s it had full docs including p.o.p. Also seen it run at Quaker City drag strip in Salem,Ohio. The rumor was 5 67 Impalas were sold with the hipo engine but I have never seen one nor have any been documented. If it were real it would have a 12 bolt rearend and big sway bar on the front.

Re: 427/425 Biscayne?
 

I know you are talking about 1967,but I once owned a 1966 Impala with a factory 427/425.Only 1856 made.We found paper on it and brought it home.That car beat an LS-6 balls out!
But the next year they only offered the L36 427/385Hp in this carline.

Re: 427/425 Biscayne?
 

There was also a 1966 427/425 Biscayne in the Roselle area for a while. It was black with a blue interior and 4 speed.
It was also the real deal.

Re: 427/425 Biscayne?
 

425/425's were offered from 1966-1969 in all of the big car line but the '67 is the only year that is very questionable.

And Rick, thanks for pointing out that these big cars had potential. I am very pleased with the power of my cars but am seldom invited anywhere. [img]/ubbthreads/images/icons/blush.gif[/img]

Re: 427/425 Biscayne?
 

The big cars are definately underrated. If I get my car to hook up it runs pretty well. At the local track it has gone 13.65 @ 102 is my best pass ever in it. Its just tuff with a stick car. The red 66 is a pretty neat car, I havent see it in a long time. I also remember a 66 427 wagon with a 4 gear out there too, along with a 409 64 wagon. Micky

Re: 427/425 Biscayne?
 

Rick,

I agree about the potential of the big cars with the 425's. They were huge in size but didn't weigh all that much more than the Chevelle. Plus the 427's wrapped quicker than the long stroke '54's. There's a Red '65 427 here in town and a Marina Blue '66 425 HP a few miles East of here and they're still with their original owners. The '66 was a regular at the local strip through the early '70's and made believers out of a lot of us.

Maybe you don't get the invitations for fear of being humiliated by those heavy breathing behemoths! They're welcome down here ANYTIME.

Re: 427/425 Biscayne?
 

Here's one for ya! Vintage shot in action.......

Re: 427/425 Biscayne?
 

I know we've covered this before, but the topic of the "generous" exhaust manifolds of the '65 and '66 BIG cars came up recently on the Pure Stock board, and it got me to checking. What I found (and Rick had probably already told me this!) was that the '65 L-78 big cars shared exhaust manifolds with the '65 Corvettes, whereas the '66 L-72 big cars shared exhaust manifolds with the '66-69 Corvettes!

Here is a picture of a set of '66 L-72 big car &amp;'66-'69 Corvette manifolds. And, here is a picture of what the standard fare 385hp manifolds off a '68 big car. What a DIFFERENCE!

As for the L-72, I gotta tell ya, it may be sour grapes since I sold my LS-6 to pick up a Yenko Chevelle, but I like the 427 better for racing. To me, it seems like the perfect blend: the bore of the 454, with the stroke of the 396.

Re: 427/425 Biscayne?
 

Our parts man at work used to work at Economy chevrolet in Rock Island Il. A couple of the guys he ran with bought 1966 427 powered big cars. Rosco Davidson had a fully loaded silver Impala with a 4 speed that he ran at Cordova drag strip. "Fat Jack" Reynolds had an aztek bronze Biscayne, rubber floor mat, radio delete, 4 speed with 4.88 gears. Madsen says he took it home and pulled the motor and had it balanced and blue printed. While he was waiting on that installed fiberglass fenders, hood, deck lid and bumpers. Says he never ran it at the strip just on the 1ways in Rock Island. Madsen has a Rock Island Argus paper with an article on the street racing in Rock Island

Re: 427/425 Biscayne?
 

Along the same line of thought...what exhaust manifolds did the '68 &amp; '69 L-72 big cars get? The same as the Corvettes, or the same crappy ones as the 385hp?

Re: 427/425 Biscayne?
 

Rob here are some nice cast iron manifolds for you -
1963 427 Mystery Motor

Re: 427/425 Biscayne?
 

Rob,

My vote too. I love the LS-6 but inch for inch the 427 will probably remain the all time king.

Re: 427/425 Biscayne?
 

Hey 68l30, thats my car, where did you get the photo?

Re: 427/425 Biscayne?
 

The 68's are the junk manifolds, not the vette style.

Re: 427/425 Biscayne?
 

Elvis was the "king" but the LS6 was the "Bully of the Boulevard". [img]/ubbthreads/images/icons/cool.gif[/img]

Re: 427/425 Biscayne?
 

Here is a hot look'n 67 Biscayne. Not an L72, but still a nice car. I too have been looking for the allusive 67 L72 big car...but none to be found.

I think Casey would like this one.

Re: 427/425 Biscayne?
 

A collector in Austin by has a 66 L72 with transistor ignition and four speed. It looks like a Corvette motor got lost on the assembly line and ended up in this car.
It most certainly the original engine.

Re: 427/425 Biscayne?
 

Micky,I know it's yours.Thats why I posted. [img]/ubbthreads/images/icons/grin.gif[/img] I love that car...I think I have some others someplace.They were shot at Thompson by a certain somebody.....

Steve

Re: 427/425 Biscayne?
 

Cool car Mickey! Is that what it looks like today with the lettering still on it or is that an old pic. It has the "COPO" look with 425hp and not even any SS emblems. I like them to.

Re: 427/425 Biscayne?
 

Steve thanks, I think I know who your talking about. All I have found from him were B&amp;W shots, thats the first color lettered up photo I have seen. Joe, its been restored a long time ago, needs a little work now but really, its not up to par with the stuff I am doing now. I dont intend to do it that way either, I want to drive it some and have fun with it. It still has "battle scars" that I will never fix. The rear floor area is beat up bad along with the headliner having a couple holes from a blown driveshaft. The rear end cover has many dimples from blown gears, and the rear crossmember had too be welded from too many hard launches. I have every piece of paperwork except a build sheet for it. I will try to find a current photo, but it looks like the old car yet just with no lettering, even the rally wheels are on it yet.

Re: 427/425 Biscayne?
 

What a Nice Chevrolet you've got there Micky.Love the pix! [img]/ubbthreads/images/icons/grin.gif[/img]

Too COOL !
 

Mickey - - that is one neat piece !!!

I made that picture the wallpaper on my laptop. Very cool.

Re: Too COOL !
 

If any of you guys have old Chevy High Performance mags, check out Dec 1993. That car is on the cover. Micky was involved in a musclecar shootout with that car. He drives it like he hates it!!!!! But we know he really loves it.

Re: 427/425 Biscayne?
 

Thank you, L78Impala, for the kind words about my 67 Bel Air.I have been silently enjoying this site for quite a while. Excellent information and always something new to learn. When I saw you post the picture of my car I figured it was time to join the party. I watched the number of page views on the Casey Marks Biscayne story go past 2700 and wondered if this was turning into the Super SIZE Car registry!

Best regards,
Marc

68 Biscayne ET
'68 Biscayne-14.902 @ 99.27
Mike and son Micky Hale split the
driving duties. Mike, who hadn't been
to a dragstrip in 20 years, started off
with a 15.575 @ 96.95. Tire spinning
was the big problem, but the Hales
also changed plugs and adjusted the
valves. As the temperature went up,
so did the times. The best Mickey
could muster in the 98
heat was
16.608 @ 94.98. After Mike clicked off
a 15.269 @ 98.68 the next morning,
Mickey recorded runs of 15.053 @
99.27 and 14.902 @ 99.44.

Marc,
Fantastic! That's one of the best things about this site. It drags all these cars from the past out of the closet where we can all enjoy them again. Glad you're here. Now, tell us some stories!!!
