Well if your going to Turbo it than the Compression Ratio (C.R.) is maybe about right with the .030 overbore you are at 8.33 to 1 Static, a 58 CC Head combustion Chamber and the FelPro .050 Comp Head gasket would then put you at a 8.5 to 1 C.R.
I was mistaken about the cam spacer. The one I have must be for a different application. It's a c5az-6265-a and does not fit the cam nose. It will push the cam too far bark when installed. Do you know the part number for the correct part?How about this. With the cam pin removed from the cam, place the spacer the on the cam snout with the inside bevel facing the cam journal. now install pin with the spacer between the pin and cam journal. I do this before putting the cam in the block, then install cam using a long 7/16 course bolt as a handle, then cam thrust /retainer plate and bolt down, and then install the timing chain sprocket set. Make sure that you line up the crank sprocket timing mark and the cam timing mark before final chain and sprocket install. Sometimes the cam will get pushed back to far and fight you, just keep it pried forward.
Machine shop scrapped it. Vintage inlines doesn't respond when I try to order from them. ThanksNo, I do not know the part number, I have just taken them off of old cams. Vintage Inlines has some. Where is your old cam.
I followed your procedure today with the stock timing set. Came up with 66+160=226/2=113. I have the adjustable timing set and will install in the +4 degree slot and try to degree again. I will have to come up with a new cam spacer first as the one I stole from the 170 is brokenAre you talking about boost from a turbocharger?
Did you get the camshaft set at the correct intake lobe center position?
You did not follow my procedure. You are not even close.I followed your procedure today with the stock timing set. Came up with 66+160=226/2=113. I have the adjustable timing set and will install in the +4 degree slot and try to degree again.
It's normal to see between a .001" and .002" variation as the lobe travels across the heel of the cam lobe.I have also noticed that the valve opening isn't as smooth as I would think it should be. On intake valve opening there is a .010 "blip" where there dial indicator shows initial lifter rise, goes back down to 0, and then begins the "actual" lift. Is this normal?
If this is true, Is it not possible to advance the cam more to gain more low end? Is that something that's preferable on a cam ground straight up? Or even possible at at?I don't know all the specs on your build, but with the 274 cam you will have no low end.
I hope your compression ratio is at least 10-1.
I have run that cam & replaced it after one month of use.
Go Schneider or Howard cams.
The cam card is asking you to install the cam with the intake lobe center at 105 degrees ATDC.If this is true, Is it not possible to advance the cam more to gain more low end? Is that something that's preferable on a cam ground straight up? Or even possible at at?
