What is the difference between a hydraulic roller cam and a solid roller cam?
Solid lifter cams can be a good choice for a hot street or race engine. They usually have faster ramps (lobes) than hydraulic cams, but not as fast as roller cams. They also need stouter springs than a hydraulic cam, but not nearly as stiff as a roller cam.
How much can you bore a 225 Slant Six?
See all 31 photos Iron 225 blocks can safely take a 0.060-inch overbore, but the integrally-cast iron bore liners limit the aluminum block to 0.020 inches over. Slant-Six guru Doug Dutra says, “treat any aluminum 225 like it’s made of glass.” In other words, forget about turbocharging and nitrous.
Can I put roller lifters on a flat tappet cam?
It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. Running hydraulic lifters on a solid grind raises the rpm points at which peak power and torque occur compared to using solid lifters on the same solid cam.
What’s better hydraulic roller or solid roller?
Hydraulic roller camshafts are best for street cars, where oil pressure is used to take up the lash in the valve train via a small piston in the lifter that the pushrod sits on. This means less maintenance, quieter operation, and excellent durability in daily use.
Can you run hydraulic roller lifters on a solid roller cam?
To successfully run hydraulic-roller lifters on a solid-roller profile generally requires that the solid cam profile be a tight-lash grind (under 0.020-inch hot) in the first place, with less than 30 degrees difference between the 0.020- and 0.050-inch duration specs.
Can you run roller lifters on a flat tappet cam?
It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. In terms of numbers, this means a 249-degree-duration (at 0.050-inch tappet-lift) cam ends up feeling like a 255-degree cam.
Can I use roller rockers with a flat tappet cam?
The two don’t necessarily need to be used together. Roller camshafts and lifters can be used in an engine that features nonroller rockers; by the same token, roller rocker arms can be used in an engine that features a flat-tappet solid or hydraulic camshaft.
Are slant 6 a good engine?
With a deep-skirt block and tall-short pistons, the Slant Six proved very reliable, with regular reports of engines cresting hundreds of thousands of miles, even as the rest of the car may have rotted around it. Chrysler produced Slant Six engines for its cars from 1960 through 1983 and through 1987 for Dodge trucks.
How much HP does a Slant Six have?
Specifications. The original Chrysler 225 Slant Six produced around 145 horsepower at 4,000 rpm and 215 ft. -lbs. of torque at 2,800 rpm.
