Corolla Test Pilot Posted August 11, 2006 Author Report Posted August 11, 2006 Maybe if I'd ever pulled the head off a K motor I'd understand better, but is it just the spacings of the pushrods that would limit room for intake ports? And yeah, there are plenty of pushrod crossflow engines: every single 253, 308, 350, 351, 427, ad infinitum. If anyone here can machine me one for my 3K, I'll give you $100 for it. Hehe. Quote

You would basically have to modify the engine so that the spark plugs would be in the top of the head (like a 2T), you would also somehow have to move the pushrods so they wouldnt get in the way of the ports....

Corolla Test Pilot Posted August 11, 2006 Author Report Posted August 11, 2006 Guessed as much. But it mystifies me why companies design cars with such ridiculous inefficiencies as wedge chambers, and offset plugs and siamesed ports in the first place. Doing it properly the first time would be so much easier... Quote

Would probably have to design a cylinder head from scatch: remanufacturing custom Quote
chrisandliz[RL] Posted August 11, 2006 Report Posted August 11, 2006 thats my thoughts too. it would be easyer to make a totaly new head from scratch we had to make a 5cc 4 stroke motor from scratch at tafe. so it could be done, but the standard head would be easyer to work with!!! Quote
irokin Posted August 11, 2006 Report Posted August 11, 2006 Might as well go DOHC and 16 valves while your at it.... Then you ask the question WHY.... Quote
Fat Bastard Customs Posted August 12, 2006 Report Posted August 12, 2006 I recon the easiest (read: easiest not best) way to do it would be to get a SOHC head with similar bore centers and diameters to a K motor and go from there, prolly b alot of stuffing around with water/oil galleries and head bolts though :) Quote
Teddy Posted August 12, 2006 Report Posted August 12, 2006 1) Remove 3k 2) Record & Remove engine number from 3k 3) Gain 1x 4Y 4) Remove 4Y Engine number 5) Stamp 3K Engine number onto 4Y 6) Enjoy :) Quote
