1641 is a 1300/1500/1600 bottom end with 87mm pistons.  A 1776 is the same with 90.5mm pistons, then you have 1835 (92s) and 1915s (94mm slugs).   The rap on the 92s is that they have thin walls, although they have thick wall 92s available.  There's also 88mm slugs, but their price and for the displacement increase they provide don't give you much, so go with 90.5s.  87s are also thin but they work.  If your engine runs hot, it doesn't matter how thick the cylinder walls are, you'll have problems.

OK here's my uneducated question, Why a 1641? How much horsepower is added? A1641 is basically different heads, yes? Is the purpose to give umph without machining the case? I am not saying you are wrong, mark, but I have asked this question of others before and never gotten a real answer.

 

And since we are on this subject, what is involved in "machining" the case or, for example in my 1914. Is there more than cutting to give the stroke more clearance?. Could I not do this at home? I know that line boring and such is special tools, but that should be done on all cases, no?

 

I have been led to believe that the 1776 was the strongest mod and the 1835 the worst (because of the thin cylinder wall)..

 

All these questions!

The first question is, Do you have a machine shop that you trust? My favorite engine to build is a 1641 with the 044 heads, scat c25 cam, stock stroke, 2 barrel progressive carb, and a good full flow exhaust. Most anything bigger than that your are going to have the block machined for larger cylinders.

so it has been quiet here for a while now so i decided to start a real
discussion not a brian messed up and forgot to tighten the axle nut
discussion.

so here goes:

i just aquired a dual releif case. my goal is to eventually with time and
money build a nice, carry the bus and it's shit around at 70-75 mph without
having to swap trannies type of motor. now i know folks have talked about
1835's vs. 1776's and i have heard some talk about 1914's. i know this it
should probalby be a stroker, after that i am lost. i don't really want dual
carbs because i want it to look somewhat stock. no denis, no mega squirt
either. i am thinking some sort of progressive carb. i know i will run an
external cooler and filter, probably the filter i have. i know it will have
a doghouse cooler also. so here is the big questions:

what kind of heads?
what kind of rockers?
what kind of stroke?
what kind of bore?
what kind of fuel pump?
what kind of carb?
what kind of oil pump?
am i crazy?

again i don't want a big dogg performer like what is in will's DC. what do
you all recommend?
