77 620 bulletside Posted October 24, 2016 Report Share Posted October 24, 2016 Specs for cam 162-0010 grind # Da-262-2-10. Any body help please Crane Cams Quote Link to comment
banzai510(hainz) Posted October 24, 2016 Report Share Posted October 24, 2016 most Crane cam are 450 lift so a 262 would be duration Nothing special. I would rate it a good stock cam as I run a 460 270 schneider 1 Quote Link to comment
77 620 bulletside Posted October 24, 2016 Author Report Share Posted October 24, 2016 Hows that cam work for you and wheres power band at Quote Link to comment
banzai510(hainz) Posted October 24, 2016 Report Share Posted October 24, 2016 I only have a 32/36 weber on L16(l20head) and be honest it seems OK. I would go bigger cause I put a lot of money In Cam, Springs retainers and lash pads to get maybe 3hp. If a dual sidedraft might be be more noticeable. good to 6 k for sure . Key is your distributor up to it. 1 Quote Link to comment
77 620 bulletside Posted October 24, 2016 Author Report Share Posted October 24, 2016 Im using a schneider290 f now works great from 4200-7000 3 rd gear really strong passing gear 45 mph to 70 quick Quote Link to comment
banzai510(hainz) Posted October 24, 2016 Report Share Posted October 24, 2016 well my 521 has a 4375 gear ration so that would be better for me also. and you. so don't even worry about that crane cam. you can always up the cam sprocket to 2 or 3 to get power sooner 1 Quote Link to comment
77 620 bulletside Posted October 24, 2016 Author Report Share Posted October 24, 2016 Do you no what stock valve spring pressure was at close and open lbs Quote Link to comment
datzenmike Posted October 24, 2016 Report Share Posted October 24, 2016 Intake and exhaust springs are the same There are two springs on each valve, inner and outer. Intake and exhaust spring pressure at compressed length. This would be the same as the valve at maximum lift 0.413" Outer.............. 108 lb. @ 1.161" Inner................. 56 lb. @ 0.965" Intake and exhaust spring pressure at assembled length. This would be the same as the valve closed Outer.............. 47 lb. @ 1.575" Inner................ 27 lb. @ 1.378" Quote Link to comment
77 620 bulletside Posted October 24, 2016 Author Report Share Posted October 24, 2016 Is that the open and close lbs Quote Link to comment
77 620 bulletside Posted October 24, 2016 Author Report Share Posted October 24, 2016 Together spring pressure Quote Link to comment
datzenmike Posted October 24, 2016 Report Share Posted October 24, 2016 Is that the open and close lbs Well it does involve reading...... Intake and exhaust springs are the same There are two springs on each valve, inner and outer. Intake and exhaust spring pressure at compressed length. This would be the same as the valve at maximum lift 0.413" Outer.............. 108 lb. @ 1.161" Inner................. 56 lb. @ 0.965" Intake and exhaust spring pressure at assembled length. This would be the same as the valve closed Outer.............. 47 lb. @ 1.575" Inner................ 27 lb. @ 1.378" Together spring pressure Well that would involve adding. Let me get that for you... 108 + 56 = 164lb 47 + 27 = 74 lb The factory service manual (FSM) only lists the separate spring pressures. This is for the stock cam. For higher cam lifts, I have no idea, you'll have to measure those yourself. I believe when the cam lift nears 0.480" ? the spring risks stacking. Avoid this. Quote Link to comment
77 620 bulletside Posted October 25, 2016 Author Report Share Posted October 25, 2016 Thank you all for the help Quote Link to comment
banzai510(hainz) Posted October 25, 2016 Report Share Posted October 25, 2016 since my cam is 460lift ( on this motor) lift I used one stock spring and one Motorsport spring Inner outer or visa versa. I cant remember. Its when nearing 475/480 lift you need to swap the springs as one inner or other gets close to binding. But one can cut the spring seat lower where the spring set on to leesen the pounds if you have a strong aftermarket spring. remember when a cam says 460 that with zero lash. Subract the valve las then that whats the real valve lift. so maybe minus .006 to .012 Quote Link to comment
77 620 bulletside Posted October 25, 2016 Author Report Share Posted October 25, 2016 My springs for my other cam are short by 20 lbs how much will i lose rpm wise Quote Link to comment
banzai510(hainz) Posted October 25, 2016 Report Share Posted October 25, 2016 If its a Schneider grind the closing side cam lobe has a slower closing.. What makes you think this is a proplem what you have????????????????? Isky sells valve springs Quote Link to comment
G-Duax Posted October 25, 2016 Report Share Posted October 25, 2016 Schneider also has L-series springs on their site. I'm running a set now. Quote Link to comment
77 620 bulletside Posted October 25, 2016 Author Report Share Posted October 25, 2016 The question i have is i may have to change cams for a while the cam calls for spring pressure to be 90 lbs close 180 open can i use springs rated 100 open and 200 close or will it work or cause cam problems or cam wear Quote Link to comment
77 620 bulletside Posted October 26, 2016 Author Report Share Posted October 26, 2016 To DatzenMike. Can u anwser this question Quote Link to comment
datzenmike Posted October 26, 2016 Report Share Posted October 26, 2016 No spring is 100 open and 200 closed. Other way round? Use Chevron Dello 400 or Shell Rotella T in 15w40. It contains higher levels of ZDDP anti scuff agents in it just like the oil back in the 70s. You should be running this already. You should be fine Quote Link to comment
77 620 bulletside Posted October 26, 2016 Author Report Share Posted October 26, 2016 Sorry it says my cam spring pressure is 200-210 open and 100-110 closed will these work for 180-90 or not Quote Link to comment
G-Duax Posted October 26, 2016 Report Share Posted October 26, 2016 Are your rocker arm tips, and lash pads in good shape? If so, do as Mike says, and run them. What kills cam lobes is inadequate oil quality, and high RPM. Quote Link to comment
77 620 bulletside Posted October 26, 2016 Author Report Share Posted October 26, 2016 #3 cam lobe has wear do to oil hole pluged on cam 24 yrs never a problem what are the odds so my new cam may be trash If i use old cam with new stiffer springs will it work or will it be to stiff thats all i want to no Quote Link to comment
datzenmike Posted October 27, 2016 Report Share Posted October 27, 2016 Sorry it says my cam spring pressure is 200-210 open and 100-110 closed will these work for 180-90 or not It'll be fine but get that Rotella T!!!!!! The piss they sell today that they call oil is formulated with up to half the anti scuff zinc in it, Why? because all cars made today run roller rockers. We still have 'flat tappet' cams that need protection. Quote Link to comment
77 620 bulletside Posted October 27, 2016 Author Report Share Posted October 27, 2016 Im using Z MAX and 10/40 Castrol oil I was worried about extra wear on cam because of spring pressure thanks to all Quote Link to comment
G-Duax Posted October 27, 2016 Report Share Posted October 27, 2016 Z-Max is moose milk......... (moose milk: A typicly useless additive which the primary purpose is to put your money into someone else's pocket) Mike told you what to run, do something else at your own risk. Quote Link to comment
