I have just installed a Rollmaster t/c chain set on an engine [ not a Mopar ] I am building. Chain was quite tight, tighter than I would like. Rotating the engine by hand, I heard this occasional 'clicking' noise; the noise was the chain trying to follow the cam sprocket & finally flicking off...
The hose to the A/C needs to be larger because it is operating under atmospheric pressure, whereas the PCV hose has engine vacuum [ suction ] applied to it.
Most Crane shelf grinds have 5* of advance ground into them. That means if you install the timing chain set on the '0' mark & all the machining is accurate, the ICL will be 109*.
I used a 383 block & 440 crank back in the 80s. 383s were sold here in Dodges, 400s were never sold here, so very rare. I used the 383 rods because I like the shorter rod/stroke ratio.
IMO,
The dynamic comp ratio formula/calculation is about as useful as an ashtray on a motorbike.
It uses the intake closing point as some sort of reference to the air inducted into the cyl. It takes no account on how well the port flows [ obviously some flow better than others ] &...
If someone with better computer skills than me can link this post, that would be great...
June 29 on Speedtalk.com, headed: 'Lifter manufacturers & who are they'.
Reply from CamKing who owns the forum & has been cam grinding for 40yrs:
'There is only one lifter manufacturer that still makes FT...
Are the lifters American made....or the box they come in. I do not know.
What I do know: Mike Jones aka CamKing recently stated that there is [a] only one company making FT lifters in the US & they are veeeeeery expensive. Check out on the SpeedTalk Forum.
So unless the lifters are expensive...
Do not use 'new' lifters! According to Mike Jones, aka CamKing, only one company is making FT lifters in the US & they are very expensive. I am not sure if they make Mopar lifters. The rest are 'imported', made of pure crap-anium.
Get some 25+ yr old lifters & have them re-faced; break in...
The dual 4 bbl intake in post #76 isn't going to make 600 hp, NA. Those were marine intake manifolds designed for torque in the low/midrange, right where a marine engine needs it.
Here is a Rockwell C test of lifters from Crower. Information supplied by Crower:
-66900, 66971, 66915, 66945................. 55-59 RC
-66975, 66973, 66974, 66970.....................64-65 RC.
I know which ones I would rather have in my engine.....
Is the above a sol or hyd roller cam?
I would be asking Chris Paget if they dyno tested that cam & another with the same lobes on 106-8 LSA......& how much HP the 114 lost.
The 128 rule was devised for the SB Chev by D. Vizard but he claims it works well for most parallel valve heads. Better...
I am so sick of wearing out my typing finger on this site & others.....
IF YOU DO NOT WANT YOUR FLAT TAPPET CAM AND LIFTERS TO FAIL, FIND SOME 25+ YEAR OLD LIFTERS AND HAVE THEM RE-FACED.
And no, it is not the oil.....or the lube that comes with the cam. It is soft lifter metal....
