[QUOTE="TexRex, post: 12353385, member: 251216"] [COLOR=#cd6600][B]Okay, so I had an exchange today with a friend who knows previous-era Ferrari V12s (Colombo, Lampredi and Jano), and he informed me that the biggest difference between the early TR V12s and the ones used in the GTO/GTL was larger valves and, in turn, larger throated Weber DCNs (38 vs. 36). Both were dual coil and dual distributor. The [I]tipo[/I] 168/62 was dry-sumped, but all of the competition 168s were such starting in 1961.[/B] [B][/B] [B]Certainly not the dissimilarity I thought to be the case. He indicated I may have been confusing Colombo and Lampredi 250s, where the head studs line up but water jackets and oil passages don't, in addition to equal 68mm bore and stroke in the Lampredi.[/B] [B][/B] [B]He said the first big change in the Colombo V12 came with the Four-Cam, and that included larger oil passages to feed the big heads. The larger passages were retained for all subsequent Colombo V12s and the next big change came with the 4.8 and 5.0 that required clearancing for the longer stroke.[/B][/COLOR] [/QUOTE]
