I'm trying to put together a heads/cam setup that will get me close to 450rwhp. Not dead set on that number, I just want to get somewhere near it. I've got a set of 243s I'll be sending to TEA for porting, and a ported FAST 90/90 setup. I just need a cam. The catch is, I don't want a lot of lope. I'd still like to make good power, but not have anyone notice it's cammed.

I've searched countless threads (including TXCAMSS's thread in the Dyno section about his 430rwhp, 222/226 115lsa EPS cam'd LS6), and I came up with an idea for a 224/228 cam with a wider LSA, like 116 or 117. This cam would have an overlap of -6 or -8, respectively. Not bone stock, but probably not enough for most people to notice, right? Would an LSA this wide be a problem for a 224/228 cam? I figure lift would be in the .58x range.

its gonna push your powerband higher meaning your gonna really have to rev that thing. Id call a vendor and have them custom grind you a cam for your needs.

It will just have a stock-like powerband. You shouldnt have to rev it past 6600 to get the majority of its potential before it starts falling off. It may not seem like much, but -6° or -8° of overlap is still pretty noticeable. You know a 2001-2002 stock cam has -30°.

You think with ported 243s and a ported fast that thing will even make its peak power before 6600, i bet itd still be climbing at that point.

yeah, but are you willing to shift past that? Whatever the powerband is on the cam you really don't need to go 7k's. Sure it will make some power past that, but I was just looking at it from a realistic standpoint of how he is probably going to shift it.

I think you are going to have a hard time making a true 450 rwhp with a 346 ci motor with little to no lope. It would be easy with a bigger motor, but I'm pretty sure any cam in a 346 that makes 450 to the wheels will be noticeable. JMHO.

I think you're just trying to "make **** happen" with this cam theory. Lobe profile plays a HUGE part in how smooth the cam is, due to different lobes opening/closing the valves at different speeds.

I think you can achieve your goal with TEA ported 243's and a FAST intake, but I think you're looking at the wrong cam profile to do it. FWIW, I made 460rwhp 6 years ago with primitive tuning knowledge, FAST intakes didn't exist, through an 8.8/4:10 drivetrain, with very little lope and TEA heads.

Any suggestions on the "right" cam profile?

For few extra bucks you can get a custom cam through PAT G for your ported TEA heads and FAST 90.
