Thread: Degreeing a VE...

Has anyone properly degree'd the cams in their VE? I haven't seen anyone doing this even on total rebuilds, machine work, aftermarket cams, etc. What are people using? Just lining up the timing marks and going?

i've been putting a ve together, but with undecked block, new chain,new n1 cams,tomei cam gears etc. my guys did the latter. later on i will be getting a tune and the cam gears will be adjusted then anyway.

suppose if you had a decked block/aftermarket cams you could use a degree wheel.

@shagspeed has done piston to valve clearance not sure if he's degreed cams. Shine some light sir.

My kelfords will be degreed when the engine is finally put together. Getting them both at exactly 0,0 for starters.

Its worth doing on every build really.

Me and Clark aka (Mad scientist at JWT) messed with cam timing years ago.. On our VVL Stock engine N1 Cams,intake manifold and TB .. We found the more overlap we put the more top end HP was made with no real loss in power anywhere else.. We got to the point where we used a .024 gauge locked on the big cam and turned the gears tell the valves touched the piston and locked it .028 x rocker ratio = .040ish piston to valve clearance .. We ended up with I recall 105deg total overlap and we thought we would lose power for sure but it still made more.. Not sure where it would run out because we need pistons with deeper valve pockets .. I set SS's to .050 as its a bit safer and he has SR16 pistons . SR16s are to have deeper pockets.. His runs pretty strong

@KillerKrossover did mine when I installed the frank S4 cams with SR16 non N1 pistons.

I had mazworx do it on my old 2.4. But at the end of the day we still made the most power with the cams not set where kelford wanted them.

could you translate 105* overlap to effective advance/retard of respective cams? afterall 29* of additional overall overlap is incredible!

I dont know much people going beyond the +5-5 In/Exh settings...

I will.. kind of.. N1s are 74deg.. at the cam 1deg is 2deg rotation.. As far as where it ends up im not telling.. Not because I'm a dick but because if you're going to say that cause you need to measure it out or don't do it..

bingo.
