More HP from 5.9 Magnum

Tom,
First, ignore that link to complete pos thread. Its from 2008 and who ever wrote it, knows jack.

You can install a set of our stage II valve springs that fit stock heads that allow you to run up to .550" lift cam, .575" on EQ's. I would suggest our stage II cam, its [email protected]", .510" lift with 1.6 rockers and a 114 LSA so its computer friendly. If you want a bit more, we can go up to [email protected], .530" lift with 114 LSA ,if you want to flash the pcm. Its also easy to drop a set of EQ heads on for an easy 40 hp boost over stock when combined with cam. We can get you 400 hp very easily using the factory FI set up, larger injectors, TB, pcm flash, larger cam and good exhaust. Give me a call at the shop or pm me for more details.
We just finished a very stout 5.2 build for a 67 swept side PU in Reno with the same set up, easily 350 hp. Black on black on black....the murder motor as the owner calls it.
