Here is my latest escapade. For the last 5ish years. Ive been tinkering around building a camshaft grinder, mostly centered around grinding modular ford cams, but does accept any cam with nearly 30" length. My first go at grinding i had it set up similar like an actual cam grinder. Using a...Web

by F-'88 » Mon May 16, 2011 1:52 pm. If you advance a cam in a motor the intake VTP clearance will decrease and the exhaust VTP clearance will increase. While many most mass producted street cams are made with some advance built in, many most race roller cams don't. Meaning do not assume the cam will go in "advanced" on a 106 in …Web

38+68+180=286, divide by 2 =143, subtract 38 from 143 = 105. The lobe center on this cam is 105 degrees. The method is the same on the exhaust except the opening number will be a value before bottom dead center (BBDC), the closing value will be after top dead center (ATDC) and again, subtract the smaller number.Web

Yes the cam should work wonderfully with IR induction due to the low overlap. Low overlap means less reversion, better drivability in all weather conditions and at all altitudes. More stable carburetor calibration. The exhaust valve opens early enough to make the cam forgiving about exhaust system back pressure.Web

I have a question on cam selection for an alcohol fueled 565 BBC drag engine.

Adjustment involves measuring the clearance between the rocker and valve stem with a feeler gauge and turning a threaded stud or rotating an eccentric until the clearance is a specified amount, usually about 0.006 to 0.012 inches. Measuring valve clearance with a feeler gauge and adjusting the rocker arm on a single-overhead cam …Web

I've found that it's usually a task best left to the cam grinder to make. I'm not going to get into cam selection in this article, but I should talk a bit about the effects that duration has on an engine. LSA for a performance ground cam is typically between 106-114 degrees. Sometimes even less than 106 is ground for stroker engines.Web

By Larry Carley. Jul 17, 2015. The camshaft is not only the heart of the valvetrain but the engine itself. The right cam can deliver exactly what you want. The wrong cam can be a major disappointment. One of the most important decisions an engine builder has to make when planning and building an engine is selecting the "right" camshaft.Web

Advances in lifter design, pushrod stiffness, rocker-arm geometry, and valve-spring strength have certainly allowed cam designers to try more aggressive lobe profiles, and total valve lift is sometimes a bragging point in the pits. Talk of Pro Stock or Pro Mod engines running over 1.3-inch of valve lift is not uncommon.Web
