[QUOTE="mike.s, post: 603805, member: 13548"] Thanks - no appreciate any advice! Thats a little bit concerning about the oil pressure - but will run it up hot tomorrow morning probably and see where it sits when hot. I did fit a new 26mm oil pump which i sanded down the cover surface to make it perfectly flat. Used the thin paper gasket there with no sealant. Yes - i went for the 94s - knew they would run a touch hotter, but i couldn`t afford a stroker crank and the clearancing for it - same for the cam, so used what i had from my old engine - 1.4 rockers, dells, heads, etc. i do have some 28s from old engine and assocaited jetting, but i`ll see how it goes for the minute. I was aiming for a torque monster as i won`t revving it much over 4.5k. I `ll have to coupled to a 6 rib late bay box. If you`re interested, this is the 1641 i had before - it was rebuilt stock bottom end (not by me), then i did the top - same spec as above, but 1.25 rockers, 9:1 compression, 1641cc, 28 vents- It made good power and torque all the way to 5k rpm - [img]https://image.ibb.co/nNOoP7/rolling_road.jpg[/img] [/QUOTE]
