Tuning the demon on my 416.I seem to reach the highest vacuum 8-10 inches turning the idle circuits in from being 1 1/2 turns out.Lands up being out 1 to 11/4 turns out from being seated.Any input here,Thanks Kevin.
I have read a few articles and posts on the net about muti spark ignitions not being compatible with modern dial back timing lights.As the multi spark confuses the timing signal.This does not seem to be the case as with the older style timing lights.Any input,Kevin.
Got my 416 going for 2nd time.1st time after 30 minutes crank got into windage tray.Tore completely down cut crank 10 under re honed cyls.Checked all put back together.Only thing changed was went with 928 comp springs to match cam.Inner spring slid right over seals.Starts fine but a lot of blow...
Finally getting my 416 finished.Had it all done painted and installed.Started tuned sounded great untill rpm came up.Push rods rubbing against heads.Had to face inevitable take heads off clearance push rod holes.Should be ready to go soon.Halleluah,Kevin.
Here is pict. of my 70 340.Basically a stock re built 70 340 short block.Comp cam.Edelbrock heads.Mighty Demon 825.8.0 in 1/8th 12.40 in 1/4.Through muffs on drag radials,Kevin
I bought a set of used push rods from a member.They are ball and cup and in good shape.But they are oil thru.Small hole in each end,But are correct length.Can I use them even though I dont need oil thru push rods.Your input appreciated,Thanks Kevin.
We all know advancing or retarding the timing is done with the distributor. How do you set the initial. If is there a screw or shim or what I am lost here. Need your help,Kevin.
I am looking into replacing my hedman headers with some ceramic coated. Going cheapo and would like to know who makes the summit headers and has anyone used them. I am begging that you do not mention tti or dougs any where in this thread,Thank Kevin.
What is probably the largest solid lifter cam you could use on the #5767 springs that come on edelbrock small block alum. heads in your humble opinion. Brochure says good to .575 lift but I know solids are a little different. Your input appreciated,Thanks Kevin.
I would like to move up to comp. .525 solid cam. Do you think I could get away with running the stock springs that come with the edelbrock performer heads for small blocks? It says good for lifts up to .575 but I am pretty sure that is for hyd. cams. Your input very much appreciated,Thanks Kevin.
Edelbrock now has a $50.00 rebate and I have been thinking about pulling the trigger on some #60779s. Anyone know who is offering the cheapest price on these heads right now. Thanks Kevin.
I am going to have to use some rocker arm shims that I got from Mancini is there anything special I have to do for the rocker arm oil holes the ones under the shaft on the pedastal or anything else? Thanks Kevin
