Stroke for torque: Bore for rpms. Bus engine needs torque more than rpms.
You
are limited in the rpms for a bus by the simple fact that you can't go fast.
You need torque to haul the weight and get up hills without rowing with the
tranny shift stick.
The reason 1776 and 1835 engines are popular is because they are a cheap way to
get cc's. You don't have to do anything but stick on bigger jugs. You want
the
best VW engine you are gonna have to stroke it. And as the saying goes;
horsepower cost money, how many do you want?
One of the least expensive engines is a 74 X 88 which gives you right at 1800cc
and is a great bug motor. It is my understanding that Lyle used to build a lot
of these engines for the bug.

.xls format
If the attachment to the list fails it is at:
http://texasvolksbus.org/4cylDisplacement.xls
Common numbers already filled in
2 free columns/rows for punching in numbers to play with
Someone correct me if wrong but longer stroke gives more low end torque
for equivalent bore and bigger bore gives more top end for equivalent
stroke.
Or is it the other way around?
When I was still going to Jerome and BBB Ronnie F. from Havasu swore by
the 1835 he built for his split. And I saw him haul a$$ up the hill in
Jerome with that bus loaded so heavy it was squatting. @Steve
Chamberlain --- you might want to call him and see about having one
built or see if he's found another formula he likes better for heavy
hauling --- http://www.bustoration.com
