engine and box anyone ?
 

Hello Greg, we could buy it together so the seller could ship it to your
address in UK and you could keep the box whilst I'd love the engine! What
would you think of this?

sounds good for stock !

I'll give you a call

Hi All,

from the pictures it looks like a "wedge" engine.
Does these engines fit in a Bristol 407 - 410

Peter

I will check tomorrow

Unfortunately, I am not a Bristol expert. However, I am pretty sure that
early model V8's were "Polysphere" 313's and 318's. About 1967 or 1968,
Mopar switched from the Polysphere engine to a smaller wedge head engine.
This engine evolved into the 340 and 360 cubic inch engines.

According to Setright's "LITTLE RED BOOK", the 407, 408, and probably 409
should have been Polysphere engines. The 410 could have been either
engine, but I would "guess" that it was the small block wedge head engine. The
engine for sale has rectangular valve covers and is definitely a late wedge
head. The Polysphere engine has different looking valve covers.

Of course, the 411 is a completely different animal with the 383.

That's an LA series engine. The LA series capacities were 273, 318, 340 & 360.

The LA 360 engines were used in the Bristol 603, Britannia and Brigand. The 603E had a 318 engine, which I assume is also an LA series, but I don't know for sure.

The V8 used in the Bristol 407, 408, 409 and 410 was the earlier generation A series engine - 313 in the 407/408 and 318 in the 409 and 410.

Unfortunately the A series, also known as the Poly (head), has pretty much been forgotten and people often refer to the LA series simply as the A series, which can get confusing for Bristol owners!

The 411 was first fitted with the 383 B Block engine, then the 411 S4 & S5 had the 400 B Block engine.

Both the LA series AND B Block engine were a "wedge head" design.

The LA series was a strong engine and is much more tunable than the A series. There are many after market components available for the LA series engine.

I hope this helps.

Regards,
Kevin

Just realised something ...

The eBay ad says the engine came out of 72 Challenger, which used the LA engine, but the ad title says it's a Dodge Plymouth engine. I think some 'Plodges' used the old A series engine!

Best to see if you can get the engine block casting number to be sure.

For an LA series engine, the casting number on the block should be one of these;

2536030-318
2566080
2806030

Hi,
.
That's what I thought, there are some obvious differences between the 'photos and the 407,408, 313 engine and indeed the later 408/409.

The engine advertised for sale is definitely a later wedge head engine. I
last owned a "Polysphere" 318 around 1972, but if you put it side by side
with a later wedge 318, the difference in appearance is quite easy to see.
The valve covers are much different, just for a start. In 1971, federal
exhaust standards resulted in some very poor modifications to current
engines, resulting in much lower performance and poor fuel mileage. A 318 from a
1969 or 1970 would be much preferred, but might have to have the valve
seats replaced to handle lead free fuel. What I don't know is if engines sold
in Great Britain were stuck with the low compression, retarded timing,
exhaust gas recirculation, and other "fixes" required on our cars.

As for the Dodge Plymouth reference, this is probably because they are
identical cars with different badges and slight sheet metal differences.
Unlike General Motors, which used a different engine in every line of cars,
which probably contributed to their bankruptcy, Mopar made several engines, but
they were used across brand lines. I never could understand why Chevy,
Pontiac, Oldsmobile, and Buick all had a 350 cubic inch V8 at one time or
another, but none of the major parts would interchange.

In the early Flat Head days, Ford and Mercury were different in that the
Mercury had a 1/4 inch longer stroke and a bit more power to make up for
it's heavier weight. In later years, the only difference between a Ford and
a Mercury were badges and a bit of sheet metal. The engines and
transmissions were identical. Mercury is now an "Orphan" and no longer made.

Hello,



this Challenger engine is quite evidently a 'LA' engine, thus more modern
than the 'A' Poly I have on my 409 (or I would to say off my 409, as it lays
dismantled in several hundreds of parts scattered between Bologna, Imola,
Faenza and....the broken parts shelf of my garage). I think the external
dimension, engine supports, gearbox attachment etc, might be exactly the
same, though, so mny idea would be to purchase it (if Greg can arrange the
shipment to Europe of this lump) and have it tuned a bit a spare engine for
my 409.



It's all Jim's fault if I am trying to do this: his wonderful tales of
night racing along US Highways chasing bad guys on his black and whites made
me think that a hot American V8 would be good to have in my garage....well
concealed under the dignified hood of a Bristol, of course!

Ciao

Stefano:

Thank you for the complement. In the case of the engine for sale, the
only attractive part is he price. If you want my opinion on a proper power
plant for your 409?, I would look at one of the high performance 340 cubic
inch small block wedge head engines. The "King" of these engines was the 340
"Six Pack" which came with a hot cam and three two barrel carburetors. I
think they were Rochesters, but could have been Carters.

These engines were supplied in the AAR Cuda and were made to be eligible in
Trans Am racing. The 1972 318 was "Normally" a low performance engine
made for the bottom of the line. However, it looks, from the picture that it
may have a four barrel carburetor manifold. This was either not common,
or not even available on a 318 in 1972.

These engines were dogs, at least as specified in the USA. For example,
the 1970 Mopar 318 two barrel carburetor engine was rated at 230 HP and 320
pounds/feet of torque @ 3000RPM. The peak horsepower was listed at 4400
RPM. There were no four barrel carburetor options listed because the 318 was
considered the bottom of the line, other than a couple of inline six
cylinders.

In 1972, the same engine was rated at 150 HP at 4000 RPM and 260
pounds/feet of torque at 1600 RPM. The compression had been lowered from 8.8 to one
to 8.6 to one.

One caveat is that they changed the way power was rated and the later
engines were as installed in the chassis, vs strapped to a dynometer.

The high point for the small block Mopar was probably 1971, where the 340
cubic inch AAR engine had three carburetors, a 10.2 compression ratio,
hotter cam, and produced a conservative 290HP at 5000 RPM and peak torque of 340
@ 3200.

The differences between the potent 273 Cubic inch high performance engine
which produced 235 HP at 5200 RPM and the 318, which was never equipped with
a four barrel carburetor in the states, (at least, I can't find one
listed) was bore size. The same goes for the more potent 340, which all came
with a four barrel carburetor. The 360 was a slightly smaller bore, but
longer stroke engine, and again, it was never considered a performance engine
here and only came with a two barrel carburetor.

The 400 was introduced to help make up for the serious loss in performance
in the 383 after the federally mandated smog rules that took full effect in
1972 and got worse in 1975. Most police cruisers and high performance
Dodge and Plymouth cars, such as the Road Runner came with a 325 HP 383. After
de-smoging, the same car came with a 400 cubic inch engine rated at 260
HP. At that time, we switched to the 440 cubic inch engine, which were rated
at 280 HP with dual exhaust. The single exhaust models were true dogs and
were prone to setting brush on fire if driven through high dry grass.

If you want to keep up on the German freeway, you can always order a 408
cubic inch stroked LA 360 engine with a hot cam, Edelbrock air gap manifold,
and good cast iron heads. The base price is$4000 US Peso's. Up grades
can add $1500 to that. These engines are rated at 375 HP and 460 pounds of
torque.

I am sure there are better places to get Mopar engines, as Summit sticks
with high volume stuff, which means big and small block Chevy engines and
some Fords. I don't know what shipping would be, and I doubt I could manage
to get into my "carry on" luggage.

Dream on.

Jim.

About Us

This company will build any of the Chrysler engines to what HP you want for around £3000 delivered to Europe.

They told me about 450 HP limit without changing the torque converter but just tell them what you need !

As Jim says -- Dream on :-)

The blonde lady is only available with the Hemmi !

The price of £3000 was for a 383 to match a 411 S1 /S2
