Gary what other details would you like to see?

A photograph from the side (showing the rim around the big end - journal end) of the rod.  That will show whether it's a 'std' rod (used in most non-hp small blocks), or the HD rod which was used in the higher performance small blocks thru the 60's.

Good morning!!
Will take some pics tonight.  Big holiday up here,  St. Jean Baptiste and we a goin' up North to the Laurentians for the day.
Has been a wee bit warmish eh boys!? 

In the future, I am going to try a  a sound idle clip of my old NHRA cheater cam by Cam Dynamics with  something like  .384 lifts both sides and  245 degrees duration.
This cam has to be from the late 70s.  All this in a 355 c.i. but, with 76 cc  early, heavy 882 heads.  Still pops a wee bit though.

Here you go Mr. Gary.

"1967 302s used the standard small journal rod of the time with a pressed in wrist pin and 5/16" rod bolts."

Many of the 67 Z28s saw track time and their engines were enhanced by Traco and others. I bet few if any ran in stock form.

Traco replaced the wrist pins with aftermarket in everything.
EXCEPT THE 67 L88... which to Chevrolet they recommended  replacing  prior to LEMANS.
Chevrolet stated they wanted to WIN LEMANS with a STOCK engine to ADVERTISE as such...  Ironic that they LOST LEMANS because when in front by what seemed an insurmountable of a lead the Corvette was taken out by broken wrist pin windowing the block..

The photos didn't show much of what I was looking for, but his rod appears to be the 'std' heavy duty rod for the mid 60's.   Used in 327's from 300 hp on up.   Those same rods were used in '67 302 engines, although they may have been subjected to additional processing prior to being put into the 302 engines.   The '67 302 I had used the same rods (run in NHRA stock classes which limited what parts could be used), although in my engine the 'stock' rods had been subjected to 'Hank the Crank's further work, as did the stock crankshaft...   In the stock classes, the parts had to be 'stock production', but they allowed additional work to be done to them.

Thanks a lot Gary W  and  bcmiller for helping out on my  302 small journal  connecting rod identification.  One should remember that with only 3 - 4 light runs in a 3600 +
Firebird, that there was not time to wear the yellowish fogging from my rods vis-a-vis the pink rod that Mr. BCM put up for us. 
I was Googling the  Tracy Performance   site and the info on there with  pictures was very interesting to say the least.  I am sure the connecting rods on there are called
1967 302 SJ  "Floater"  Rods.   I believe the information was found under Vintage Parts > then Crankshafts > then look for the various early First Gen. connecting rods.
Great clear photos on this Tracy site.
I will post pics up when I get the TRW 060 Powerforged slugs from the 302 SJ rods for your interest showing the small ends of the connecting rods.
Anybody else want to chime in, I would appreciate it.
Have a great Sunday gentlemen!!
Ted
