Decoding/Numbers / 3917291 heads

« on: September 17, 2010, 07:09:42 PM »

OK, someone tell me what's up with the 'dual' format 3917291 heads. As far as I know the 67 built heads came in two versions based on the valve sizes and they didn't have the temp sensor fitting. The 68 heads also came in the same two versions but had the temp sensor fitting. So why don't  head castings dated late 67(for 68 model year) have the temp sensor fitting?  Was it only after Jan 1 08 castings did the heads have the temp sensor fitting?

General Discussion / 68 Z/28 EXHAUST MANIFOLD OUTLET FLANGE BOLTS

« on: September 10, 2010, 08:04:41 PM »

I have a 68 Z/28 04A build and I want to know what type/size bolts were used to connect the exhaust pipe to the exhaust header outlet flange? My left side manifold (3872683 dated C18) has I believe are 3/8 coarse thread bolts, both going into the manifold and for attaching exhaust pipe. My right side manifold (3872730 dated D18) has, again I believe,  3/8 coarse thread going into the manifold but fine thread to attach exhaust pipe. Any known reason for this except that the right side has the heat riser?

General Discussion / 302 vin vs assembly date

« on: July 25, 2010, 07:46:00 PM »

Hi Guys; I'm looking at two 68 302's one has a VIN of 18L397887 and assembly date of 0404 and the other is 18N412897 and a 0329 assembly date. My question is, are these both 'in-sync' with their numbers? The LA build has a older VIN and a later assembly date over the NOR motor which has a newer VIN with an eariler assembly date. I'm looking for a replacement motor for my 68 Z/28 (no motor in car when I bought it, VIN 423105 04A).
