Being that this is my first rebuild, I came across an engine with a stamped code of B on it. This one also cam out of a semi auto chasis so I know it doesn't have many miles upon the engine. Any help would be appericated. Thanks, Matt

Post the whole serial number and someone can tell you how it started life.

possibly a '68 69 70 model

all I could see at the moment was a 211 101 1010. I couldn't see any more numbers at the moment [rain hinders all].

That's 211 is the part number. The number in question is beneath the alt/gen stand. B something, about 6 digits.
I'd almost bet it's a B5XXXXX.

July '70 or later. http://www.davisracing.com/engineid.php

What are the rebuild plans? This is a single port/single relief engine case.

Hiya Suck,

B6878919 may be a bit of a problem.

The first digit following the "B" indicates that this engine was one of the 600,000 run during the 1970 production year (August 1969 to July 1970) for use in a Type 1 application. However "B" series engine numbering began at B6000001 and ended at B6600000. Your B6878919 would seem to fall outside this range. Are you sure that the second digit is an "8" and not, perhaps a "3"?

By the way, not all of the "B" series engines were single relief cases. VW switched during the production year. The higher number cases are dual relief cases and primo for rebuilding.

Yep, you are right, I had forgotten about that. I'd still have it gone over carefully. A performance engine might be better in a newer case.

thank you for all of the help. I have been trying to get outside, but the rain has been hindering that. What do you guys think about a 1776 as a daily driver?

I'd think about another case besides the B for more than a stock engine.

H cases and B's are not the best (IMO) choice for paying to have machined for bigger cyl's... Better off with a later model AH or AK with the factory small stud inserts, or like was stated even a new case if you can swing it.

All B6... cases are dual relief as VW introduced this spec at the beginning of the 1970 model year. The confusion will come about because there were B0.. and B5... produced at the same time as the B6... but all B engines up to 69 were single relief and all after that were dual.
