302 Trans Am pistons
« on: February 17, 2018, 06:39:39 PM »
All
I have came across a piston/rod combo, that I would like to learn more about. They are a 5.7 sm. journal BRC rod, 4"bore piston using single ring and single lock on piston pin. Only markings on pistons are casting of 51010 on inside. Supposedly they are road racing 302. that have been packed away for years.
Compression distance measures closer to 350 piston or possibly a 6" rod 302....? not the 5.7 with them
Curious if anyone remembers this, or a similar combo used in any first or second gen. LT1 trans am racing.

Thanks in advance.

I would think it would be unusual to road race with aluminum connecting rods.

I thought the same about using one ring on a long road course race

I'm with 1109.  An aluminum rod would indicate a drag racing intent rather than road racing, in my opinion.
