What kind of camshaft should I use for a 406 SBC?
What kind of camshaft should I use for a 406 SBC?
I would use comp cams XFI lobes and the 1.6 rockers. The 274 XFI intake lobe will give you around .535 lift with the 1.6 rocker. Silver75, are you going to use the stock 400 5.565″ rods or are you going to use a longer 5.7″ or 6″ rod?
What should the bottom end of a 406 be made of?
Here’s what I was thinking. Rebuilt bottom end with splayed 4-bolt caps, forged crank, pistons and h-beam rods.
What kind of roller lifter do I need for roller cams?
From left to right is an OEM-style hydraulic roller lifter, an aftermarket retrofit hydraulic roller lifter, and a mechanical roller lifter. Taller hydraulic roller lifters also mean shorter-length pushrods for roller cam engines compared to either flat tappet or mechanical roller cams.
How big is the quench area on a 406?
10.25:1 compression ratio with a quench area of about .045″. Runs on pump premium and with 50° of total timing there is no detonation. The most expensive part of the whole engine was the heads, but they sure help make the power.

Do you need hydraulic roller lifters for roller cams?
Taller hydraulic roller lifters also mean shorter-length pushrods for roller cam engines compared to either flat tappet or mechanical roller cams. If you are planning on using a mechanical fuel pump with a steel roller cam, you also need a special fuel pump pushrod.

What kind of compression ratio does a 406 have?
Nothing needed to be clearanced, just normal machine work. 10.25:1 compression ratio with a quench area of about .045″. Runs on pump premium and with 50° of total timing there is no detonation. The most expensive part of the whole engine was the heads, but they sure help make the power.
