Well still more goodies ,,,I hate that so many things way back when had no numbers.lol.. Found old drag shocks,,wheel spiders,NOS sparkle aluminum rims. and boxes of pistons and rods ( all unmarked of course ). anywho These Mickey Thompson rods only markings are a T,it is about 8 1/2 inches long and the crank size looks to be. ( see picture as im not really sure how to say that measurement) Without numbers what is teh best way to ID rods?
I have one Mickey Thompson aluminum rod that I got to make into a steering column hanger, and I'd like to know what engine it was made for. Dave http://www.roadsters.com/
Get a micrometer and determine rod length (center-to-center), pin size, journal size, and journal width. That should tell you enough to identify the first rod. The part number on the second one should turn something up.
Big end ID appeares to be around 2.312 Say Two inches three twelve. Common pin size is .990. Measure with your vernier caliper from the big end edge closest to the small end edge. Then add half of the big end diameter and half of the small end diameter and you have center to center lenth. It's a start.
I can't help you with a number but I have a set of those M/T aluminum rods in a sbc. It is a high winding beast!!!!
Big Block Chevys have a rod bearing bore of 2.325 and a pin diameter of .990. Maybe that's what you have. Why don't you spend $20 and get a dial caliper? Lot eaiser to read. Especially for old guys.
Old TRW engine parts catalog had dimensional section on the rebuilt rods...they aren't in that business anymore, but likely local car parts store has a similar line catalog.
