Reher Morrison the best, impressed they have some video's, loved when they had Tech on CHP magazine always correct but not many secrets Airflow that's the ticket Thanks for this stuff
Man this was REALLY GOOD, I wish he had closed with a more detailed explanation as a conclusion. Being a first time for me, it leaves me thinking what next.
This was a good video and I'm not complaining but next time backup the camera so we can see everything the dial gauge and the wheel and the direction of the man turning the wheel . Leaves out the guess work for dummies like myself . I'm visual so I can mimic what you're doing. But thanks for sharing your knowledge. Blessings and more Blessings
got a question for u my brother....i got 1990 k5 blazer 5.7 just got the enging rebuild still have the swirl port heads on it and its pretty mush stock i have high perfomace intake im eliminating the computing trying to make my mine up if im going to go with a carb or some efi sniper..i have 700r4 trans and 4.10 gears and up graded my torque convert to a 2000 to 2400 stall ..it has a up grade cam in it howard cams ratter 188005-09 lift .525/530 and duration .050 ; 227/235 centerline 103 i want to no is that a good cam to go with them swirl port heads and would i be able to hear the cam..i dont no to mush about cams..i no the vortec or aluminum heads would have been better but the engine was already build already..i do have headers 3 inche pipes all the way back
1:34 Could you explain that differently ? How is the locating dowel position relative to the base circle of the cam lobe determined ? Is it installed before grinding ? I would think yes as it would act as a dog to spin it between centers yes ? I should watch a video on how a cam is made.
When the cam is made , the dowel is installed prior to the cam being ground. A drive is fixed to the dowel end. The cam grinding process / profile is then completed. The dowel is the datum. You sometimes read the cam is ground 3deg advance. In that case the drive end (usually supported in a chuck) is then clocked the 3deg and the grind process begins. I hope this helped.
So which way do you turn the adjustable camshaft gear if you find the lobe centerline being off based of off the cam card? This video didn't really explain that.
You are correct , the piston is not truly at TDC ,you take the measurement just before/after the piston reaches TDC because of piston dwell....every engine has piston dwell , that amount of crank degree can vary greatly. which is why you take the measurement just before and just after
Well, hmmm I'll take that in consideration and run that across to Johnny .. What I can say is that process has shown lots of horsepower on the dyno over the years ..
