V10 in 64 valiant

I made a Jaguar V12 installation in a 65 Valiant 27 years ago, with twin turbos. It was a tight fit, and needed to relocate the brake master/power, alter the inner fenders, make a custom radiator fit inside the opening, and firewall changes. Weight distribution was bad. A stroked small block is a much better solution, my

i have BMW M5 S85B50 engine on my engine mount waiting for a mopar where to drop it
and it is shorter than a BBM

and a decent powerplat with turbos

The engine fits better than you would think because it is basically a skirted small block with two extra cylinders. Magnum motors are shorter than an older small block because of the shorter water pump and no fuel pump eccentric. The V10 is only a couple of inches longer than an old small block. It is of course for a daily driver I have a set of w5 heads and an r block for my other car. I have a 340 with w2 heads already in my other other car I would like to take out and restore being a factory v8 4spd 2dr hard top signet 200 red on red. I am finally finishing up my 1500sqft addition after several years and will have the space in my garage as well as finances to do several things that have been put on hold for years. With all that said how heavy is a v10 I know the 4sp auto is a bit heavier but is it that much more than a slant 6 with cast iron everything. They even have magnesium valve covers.

I wouldn't do it. I love the power of my V10 Ram but would never consider swapping it into anything after owning one. They get about 9mpg loaded or not and only make around 310hp. Yeah so it makes 450ftlb but for the shear weight and lack of any aftermarket parts except cam and headers, I would swap anything but that into the Valiant

We had a PT Crusier with a V10 in it on display at
work.. looked cool but it sure was full up front..
I dont know who installed it weather it was guys at
Chrysler did it or a outside company... it was the
Viper engine and trans

for a daily driver, i think that v10 would be nice... killer torque on 87 octane crap.....throw some 2.76's in the rear and hit the highway, just too bad those v10's sound dumb and are so heavy.
I can't imagine the fuel mileage being as horrendous as it is in a pickup truck.

To keep it injected he will have to pull ALL of the
wiring and the computer.. thats the way I would go
EDIT
And I would go with the trans also.. in a light car
it will get good mileage with OD and lock up

Well that was my thought. I wanted to do a magnum motor w/ac but the v10 seem to be easier to find with low miles. I have found a few trucks around 100,000 miles for $1600. I could rip out everything I need and sell or scrap the rest. The rear sump pan might be a small problem the trans tunnel will need work but that would be the same on either. I am going to have to play with the fuel pump. The factory has a built in regulator so I need to either find a way of using it in a fuel cell in the trunk or use a different regulator. I am concerned about the weight and the clearance for the exhaust manifolds. I am hoping they will fit if not I have seen cheap headers on ebay that I could modify to fit. Does anyone know what the weight actually is on the complete motor.

I would think the worst thing would be trying to get headers in it. They are a challenge even with a small block.

That guy in the BMW makes John Force's burnouts look like dry hops...
