Re: 1956 built 4360 Fuel Injection units
I have the 69th Rochester fi unit built. no Rochester tag riveted to its doghouse. I believe the 69 is stamped on the rear wall of the doghouse but I may have it assbackwards. mike -

My #32 is stamped 132 in the area where RPD tag is normally found. Original foil tag still in place.Comment

Re: 1956 built 4360 Fuel Injection units
I think there could be a plenum number separate from the unit # as each part was marked. I believe the first 50 to 100 units were lab made using in some cases non sequential numbered parts to achieve the best performanceComment

Re: 1956 built 4360 Fuel Injection units
Joe, I have 1016. Stamped in front of the plenum. It's buried so I can't easily take pics of it. Needs gone over again. The first couple dozen '4360's were sent to Smokey (Henry) for testing purposes I am told. Wish I could tell you more. Haven't looked at the unit for at least 20 years. JohnComment

i would be happy to swap pictures as there is little known about these early units. Yes there was an order for early units to be sent to Smokey and also to SEDCO. However some orders were not fulfilled due the early shortage of available units. The history on this time is marvelous and involves all the key players.
It it would be interesting to me if your early unit is stamped on the fron or the back of the plenum and what size type. Real early stamp size was deemed too small to read so it was enlarged. I forget offhand the exact measurements. Ken details it in his book.
My unit is complete including the foil tag.

16 if stamped on the front or back of the plenum may be the sequence # of the plenum ( 16 the plenum of a batch ). The FI assembled unit # could be different. My unit 32 is stamped 132 where the RPD tag is normally found. I have to check the front Plenum stamp.

Re: 1956 built 4360 Fuel Injection units
Joe, Its stamped on the front of the plenum. Its not just the plenum on this unit. Its the 16th unit built. 1016. Stamped on the drivers side leg of the front of the plenum
By the way. The number 132 stamped may not be the fuel injection number Joe. I have seen numbers like that stamped on the air meter flange and the plenum. Inspectors or engineering numbers. Have also seen #132 on some 7014900 units.
Now '63 sandcast units from the engineering center had a serial number that was a single digit. I used to own #3. Just 3.
Noland Adams book has a pic of another single digit unit but this is off tract.
Anyhow check out your plenum elsewhere Joe.
Should be a four digit number for. Anyone here have other imput?
'4360's are a science unto them self. Keep changing all the time. Why? Because they were primitive at best. Gail Parsons devoted a good part of his life making them run. He was the worlds best on '4360's.
Don Baker just refreshed my memory (and now I forgot) on when the dual spider unit went to a single spider unit. I think it's in the 1500 range.
Don loves '4360's. If you are looking in Baker correct me please.
"4360's did not use a fuel meter shield.. The also used four individual leg gaskets. Not the one piece gasket. At least in the early ones.
Not sure if Ken Kayser is on the DB or not??? He saw my 1016 an eon ago. It ha a prototype Aluminum top water outlet. Not cast iron.
But remember 1016 was not made for a Corvette at St. Louis. That may put a wrench into me selling it but honesty at all cost.
It was not even made for a pilot car friends. It was a lab unit used for testing. Around 22 units or so were sent to Smokey for testing. I imagine this is all in Kenny's book. I am not into '4360's anymore. Love '4520's on up though. JohnComment

Re: 1956 built 4360 Fuel Injection units

My understanding and belief is the first batch of usable 4360 units were lab assembled using parts that worked best together but not necessarily with all matching sequential number plenum, air meter and fuel meter. Once complete they were stamped as an assembly starting with 101. I am not sure how many were in that first batch. For some reason I believe 50 but survivors could help set it straight. Shortly after when the RPD tag was introduced the sequence for unit # restarted at 1001. My unit stamped 132 in the area where the RPD tag is attached on later units also has its original 132 stamped foil tag. The numbers stamped on the plenum, air meter and Fuel meter are different. I will provide pictures later. Unit also has white end nozzle block plugs and to my knowledge unique to the three Nassau cars and possibly the Bill Mitchell SR2 a special tall brass pressure fitting on the top of the fuel meter. Still researching and learning.
I know from an original document that the 131 4360 unit which was on a failed engine of one of the other two Nassau cars was removed and installed on another race car at engineering as I have the document detailing it.
