Roger King Posted August 15, 2022 Share Posted August 15, 2022 Look like standard rods (probably 711m), but polished on the flanks. And with better bolts fitted (Cosworth, ARP, can't be certain) Link to comment Share on other sites More sharing options...

Nigel Blandin Posted August 15, 2022 Share Posted August 15, 2022 If it is a Caterham supplied BDR, they would have been standard 711m spec rods iirc. Good for about 6500 revs. Mine had three like that and one with a bit of a kink in it! Went steel after that. Link to comment Share on other sites More sharing options...
anthony1956 Posted August 16, 2022 Author Share Posted August 16, 2022 Yes she does 7,000 easily and as that's max on the rev counter I never go above that.She was bought CKD and engine from Cosworth, he told me. 20 years ago now. Link to comment Share on other sites More sharing options...
