If you are wondering about what size cam is in a stock Chevy 350, read the full article below. But practically the case is not like this. Many people think that the bigger the cam is, the better.
When the valves open, gasoline enters into the cylinders. Some cam lubes will run off the cam if you let the engine sit for a few days before starting it.Suppose the engine of the car is the heart, then the camshaft is the veins of it – which supply the fuel.Ĭamshaft basically works by rotating and creating energy, that opens up the valves. I do lube lifter bodies with the break in oil also. Molly paste on cam lobes and lifter face and Gibbs /Driven break in oil and no other additives.Īll lifters spin in the holes.
I run crower cam saver lifters now for my hydraulic and Howards direct lube solids for the solid flat tappet. On the flat tappet failure i have not lost a cam since the 2007 era when ZDDP was reduced and I did not know about it. No idea how large your cam is now but I would not be afraid of a. The finishes and prep are key to making it work that could be why you get conflicting reports as to if it works or not. To take an old engine with no trick intake runner finish and sharp edges and large chamber and start building large amounts of cylinder pressure would be a trial and error thing more than likely. Blend the sharp edges on the edge of the chambers and valve reliefs etc. very happy at 38 total timing and 91 octane.Īnother thing i did to all my builds was rough up the entire intake runner during porting to keep fuel atomized.Īnd all sharp edges were removed from the combustion space. ran it in that 10.87 for many years and nearly 100,000 miles 225 psi cranking pressure. I ran the 268H in many engines with as much as 10.87 compression. you need to look at intake valve closing point, if you want less pressure in the cylinder you need to close the intake valve later. Just because a cam has a 114LSA does not mean it will close the intake valve later than another cam on a 110 LSA. Smaller chamber heads are less detonation sensitive. Lots of compression and smallish cams but small chamber heads were the key. I have done it many times with the 350" engine.
