Subject: BOP engine
I have heard from many people about the lightness of the BOP V8.
Well I was going to put one in an Alpine (had the 1594 3 main engine).
SO I bought a Buick AND an Oldsmobile 3.5.
I couldn't even swap con rod nuts between the two...every part ,it
appeared,
of the 2 engines was totally different.
One had a Chevy type combustion chamber, the other had a pent roof
style.
Even the number of head bolts was different!!
Everyone talks about the Buick, but I think the Olds had more potential.
As for weight...I could lift the Alpine engine (w/o head) out of the
Alpine,
and set it on a fender before I climbed out....the V-8's even without
heads
were very heavy with a thick crank and eight pistons.
I don't think the Buick V8 was lighter than just about any 4 cylinder
around,
except for Pontiac Tempest's 194 c.i. slant four ,which was half of the
389 V8.
My guess was the Alpine engine full up was 180 lbs and the V8's full up
were
300 lbs.
That is lighter than a chevy (540 lbs or so )but doesn't give you a
huge advantage over
a thin wall casting such as the Ford V8 (390-440 lbs?)
The transmissions that came with the engines (3 speed manual and 2
speed automatic) were
extremely light. The auto was even lighter than the manual!

Yo;
-Mid-'70's a good friend who also worked at the same Automotive
Machine shop/Engine Rebuilder put a fairly "stock" (balanced,
rebuilt)
AL 215 V-8 with TURBO & intercooler into a DATSUN 510 wagon that
was
his wife's grocery-getter. It sure surprised the local Porsche &
280-Z
crowd. The 215 took up less room and was lighter than the stock
4-holer. Until he dialed in the springs, it looked like the
engine was
already out of the car...great for weight transfer at stop lights
but
looked like hell and was a little front-end light on the freeway.

The Ultimate AutoCross car would be a stiffened Alpine powered by the
very light Buick (Rover) 215 V-8...It's very light, about the same
weight as the Alpine engine, and with some aftermarket goodies,
capable
of over 400 HP, but easily built to be very reliable at around 300 HP,
and with the right parts, very High RPM in the 9,000 range !!! This
has
been a popular engine swap in England, and I have been trying to get
some literature on it. I have the engine, and am working on getting
the
car...ooooo Boy, will it be fast!
