No.. thats retarded.. the company wanted it installed at 112... the smaller the number is advancing it... the way it is now would be more for a nitrous engine... I would put it in at 108 to no more than 110

Not really on either of those issues.. it could reduce some heat.. but on the heat I think you have another issue.. it could be as simple as the pump not turning fast enough.. do you run a shroud on the fan.. are the fan blades just in from the edge of the shroud

I then repeated 3x on the intake valve.

You need to answer a few questions.. you checked the cam.. did you use a solid lifter... your big issue seems to be temp.. did you change any of the pulleys... things dont change if you dont do anything

You need to use a solid lifter.. on the pulleys 1 to 1 isnt gonna cut it.. you need to get the pump speed up those pulleys are more for racing than the street okay I have made a solid lifter from an old socket. it measures .900 OD. I welded a cap on it and ground it flat. I marked it so i can verify it is not spinning when doing this. Here is my question now Is this advanced on the cam 4*???

I've had several timing sets like this one, Cloyes , that the upper cam gear was off a half a tooth, it would ailn straight up and down with any of the crank gear alignments marks. They were all off a half tooth If yours are that way move the cam gear clockwise so the cam dot is to the left of the crank gear looking at it from the front One tooth is right at 12 degrees so if you want use the 0 dot for no additional cam advance The reason being some of those timing stes have two camshaft degrees advance built in a nd some don't Same thing on the cams on built in advance Good luck, you should be able to feel the difference on getting the cam dial in and advanced Let us know how it goes i am now getting 118.5* using that 4* mark on the crank gear. I am going to pull it part and set it to zero and tray again... what the heck?????

i pulled it apart set it back at zero. Next question, should my intake valve really be starting to open 30* before TDC? Only if you run baby cams Big cams starting opening @.050 from 40 BTDC to 55 BTDC with no advance The LSA affects the intake and exhaust lobes opening and closing, a cam that is ground on a 112 LSA with 250 @ .050 on both lobes will have the intake opening @ .050 further away from TDC than the same lobes ground on a 108 LSA

no change. I swapped out the water pump pulley that is 1.25" smaller diameter. i think it is something like a 24% change in water pump rpms. NO FRIGGIN CHANGE. Timing is at 15 BTDC, its a 180* thermostat. Should I go to a 160*? would it help? could it help? HELP
