Engine id number

I wouldn't get too excited by it being a real Porsche engine - it's actually a VW T4.  The 914 in Europe was tagged VW-Porsche 914. Post a picture - if it looked like a T1 all this time then it must have the Joe Cali DIY up-right conversion.  You'd know immediately it it had the 911 type cooling shroud or the DTM Raby cooling.  So you have at least 1700 cc and 80 hp.

A couple of pics would help, of the exhaust ports and intake manifolds. Don't type 4's have an oil filter boss cast into the case?

Check the heads if possible, intake ports are different, if I remember correctly the 914s are slanted while the type 4 are not. That being said there's nothing preventing the use of a type 4 block with Porsche parts. 

The spark plug ports are moved maybe 2" for 2L over the 1.7/1.8L. The Intake on the 2L had 3 studs while the 1.7/1.8L has 4 studs.  The 411/412/Bus has lower compression pistons (concave) while the 914 were convex for higher compression. The 1.7L was probably strongest built with little problems with cracks in heads. 80 hp stock isn't bad out of the box. The oil filter adapter is bolted on and can be moved/eliminated. The oil filler spout is different between the two.  All were built by VW though.  

It seems that the site "Type 4 Secrets Revealed" is no longer. It had an amazing amount of reference material including cases # info. As I remember, the case number should be stamped on the riser for the genereator stand. 

Here's a Pelican Parts page that might be of help:

Frankly I do not care if it is a Porsche block...I was curious as to what year the engine was. From my research I understand that the introduction of the 914-4 was a joint VW/Porsche project. 

Whether my block is or is not a 'Porsche' block makes no difference to me.

This engine was built by CB performance in 2009. The heads are aftermarket as is the intake and most everything else inside and out.

I do not know enough about VW/Porsche engines to quantify any friggin' thing. I just found the id numbers fell in line with a '71 1.7L 914-4. I just found it interesting that this block was used in a 1915cc rebuild.

Type 4 or Porsche block I could care less. 

My original Type 4 (which came out of a 1.7 914) was built up to a 1911cc.

Someone help me here, is a 1915cc Type 4 even possible?

1911cc would be the stock 1.7/1.8L 66 mm throw crank with 96 mm pistons/jugs.  That is a common no machining required build.  The 2.0L has a 71 mm throw crank stock.  Yeah don't think you'd get to 1915 cc - but 1911 is darn close.  

I dont think there are many after markett heads for the type 4 engine(there are some that can be converted or the scat split port heads ).have a look at the pic above and determan is yous is a type 4 or type 1. type one have the exhaust coming out the side of the heads, type 4 has them exiting the bottom of the heads.you need to identify what you realy have. my cases dont have any numbers either as they are not vw cases
. also the uni cases dont have numbers.if cb built it it probably had a new uni case, and is probably a type 1 too.

 if you want it to be a porsche just add a porsche sticker.....kinda like chevy,buick,olds,pontyaic cadda lack. ford,mercury,lincolinlogs. dodge,plymouth.and the list go's on.including vw and porch. tiodie,sion,lexs.
