Absolutley the 164 12valve cloverleaf was a different animal to the 24valve it had the bottom end torque of a 12valve engine but had different cams and was supposed to be a real screemer at the top end. According to an alfa mechanic i knew its the one to have. A lot of owners of the gtv6 put cloverleaf cams in there v6s or as they are called in the US s camsDeffo a 12valver!
Engines from stock 12v to Cloverleaf spec are different in a few subtle but important details IIRC (Heads ,cams ,poss intakes ,mapping etc - bit vague on the differences these days)Alfa simplified matters greatly with the 24v Leaf.
I have had a few 164 12vavle but never the leaf i now have a 24 valve super with the leaf intakes and youre right it does pick up at about 5k and its awesome but Id love to have a drive in an earlier 12valve cloverleaf cos i do like the low end grunt of the standard 12valve. Lets face it there all magic I am lucky as i also have a gtv6 2,5 and the sound of that engine is something else.Ive owned loads of 164's both, 12 and 24v Cloverleafs and non-Leaf 12v and 24v , and the overtaking muscle of a decent 12v Leaf is fantastic ,but I'd say the 24v Leaf has an awesome top end - you hit about 5000 RPM and the bloody thing seems to take off,just when you think it should really be getting short of breath!
If you prefer keeping the engine on the boil then the 24V has more to offer ,but the 12V seems to have more bottom to mid range .Having said that ,either one would suit me just fine!!
I am interested in the zenders could you post a pic either on here or pm me:thumbs:I have the original purchase receipt, she was first bought in 1990 in Marbella and then bought into the uk at some point.
