408 stroker build
yes..looking for recommendations on lift etc... for a street some strip 408
Don’t worry about valve lift. It’s not something to worry about unless you have a cam already with huge lift!
The pistons in the kits (or separate) have valve reliefs ready for .600+ lifts. You just have to make sure your properly timed in order to make sure the valves clear the piston during there cycle.
A combo is what you need like what 12many to James Clews left behind.
The way to choose a cam general basics.
I say this because the way a cam can be cut an show a huge difference. So below is “In General” & what you’ll find with off the shelf cams.
Duration; is going to be the operating rpm range. The cam companies give you a general RPM band range there cam will operate in. It’s not in stone but close enough for the most part.
Lift; Use as much as you can get as long as the head flows at the valve lift for the cam. Is this important? Not really huge but the more you can take advantage of the heads flow capability the better. But it is not a huge deal. Don’t sweat it.
Rate of lift; Of the valve is the quicker is better but taxing on the valve train which shortens longevity of the valve spring. It’s a catch 22 that is met in the middle with the cam grinders on there shelf cams.
LSA; Everyone loves that muscle car chop at idle. It’s the least of your worries. For a street & street strip ride, a 110 has that sound and works great with automatic transmission cars. I’d go 2*’s narrower for a manual.
Going with a 112+ often requires a rise in compression to offset a lower lack of torque and the idle starts to smooth out.
Error on the small side; This is something you have read over and over which is sometimes ignored and later regretted. Think of it this way, if you error on the smaller side, it’s added torque & probably only a few HP short of the goal. Error on the bigger side, the engine/car feels crappy down low.
Camshafts are like socks. There often changed and there are lots of verities out there to choose from. Search out lots of combinations. It’ll help in the game plan. And make a game plan and stick to it. Not sticking to it gets expensive.
