I called comp cams today to solidify my choice for a new cam and got something completely different than what I was expecting. I was told that a 224/230, .581/.588 w/114 lsa was best for my setup...what?! I have a 408 w/CNC ported 243 heads and LT w/duals...the cam I have now is a Trqr2...232/234, .595/.598...I told him I wanted more power across the power band...how is this cam going to do that? What am I missing here?.....

slow trap

comp always suggest cams much smaller than what i think would be adequate. i guess it depends on what you can live with driveability wise but something like what i have,which ic a 244/248 on a 110 +1 on xer lobes peaks fairly early and makes decent tq also.maybe something like a 238/242 or so might be a decent choice.
what is your setup like scr, rear end,trans type/stall size, and goals.

...the 408 has 10.6:1 scr with 3.73 gears, LvL 5 4L60E (Finish Line-Chuck) trans, and a 2800-3000 VIG stall. I'd like to improve the complete powerband but will be happy with gains at 3k-6k...Patrick G and Pred recommended a larger cam.. so I'm scratching my head on this one....

...I was ready to order a 242/242 with .610/.610 lift and 112+4 lsa on XE-R lobes....now I'm re-thinking if that's too big...

the rest of my setup is:
243 CNC ported heads (300cfm @.600)
.040 MLS gaskets
Pistons .010 out of the hole
dual exhaust
dual gold springs (.650)
no FI

...this is my DD, but I want it to kick SRT10 ***.......

240/240 XER lobes on a 112 +2 would be a nice "all around" type of cam.

Big enough to make some power....small enough to live with.

Dont get crazy on the advance....+2 is plenty as you will have plenty of TQ and be needing the later closing point to fill the cylinder past peak so it doesn't nose over as hard.

The Comp recommendation was out to lunch....dont lose sleep over it

Yes, that sounds practical...thanks(I also followed your gasket/quench/PTV clearance advise on earlier threads ...with success).

...not to get off the cam subject, but I'm going to put a new intake(BBK/SSI) on my 408 before the new cam...curious to know where you grind/port on your custom intakes (runners, port openings, plenum)? Any advise here or should I just leave it alone?
Thanks,

I think you will like that cam....I almost quoted you a high 230's intake lobe but after reading a few more of your posts decided slightly larger might be in order.

Concerning the FAST, while most people may think "you just knock off the flashing" or smooth some of the edges (blah, blah, blah), the people who have seen and used my intakes will tell you the work performed is far more complicated and involved than that. What Im beating around the bush trying to say is to really improve upon it takes a lot of time and some skills (not to mention the right tools), so my advice is consider having me or someone you trust port it or bolt it on stock. I would encourage you to have it ported as a little more money invested now can nearly double your potential gains of the install. Even at the price I charge to do a very thorough and neat job, it still knocks your cost per HP down considerably, adding to the value of the swap and obviously tacking more on to your bottom line in total power gains.

This hobby is a disease....while its easier on the wallet to dismiss the extra 10 or so from the porting now, I will bet you anything you will be searching high and low for it later. Its just the nature of what we do....

To directly answer your question however, my advice is to leave it alone or send it to a qualified professional.

Good luck with the build...

Tony

Tony,
Would a 240/244 on 114 LSA (then advanced +4 for a 110 ICL) have a similiar result as your 240/240 112LSA recommendation?

The events are:
IVO: 10
IVC: 50
EVO: 60
EVC: 4
Overlap is 14

I found this cam for 1/2 the price of the new 240/240 112lsa and was just wandering if they would perform the same before I spend 2x the $$$...

Here is a link to one of my cousin's problems( https://ls1tech.com/forums/manual-transmission/747636-ram-twin-disk-clutch-system.html ). His motor is a 402 with RHS 225 heads, Fast(my port work) 90mm, LS2 TB (again ported by me), 85mm mass air, SLP 1 3/4" headers(for now), Kooks 3" X-pipe w/cats, and TPIS cat back. The cam I used is 247/247 @0.050", .622"/.622" lift, on a 110+2. His compression ratio is 11.67:1 SCR and 9.27 DCR. His car runs on 93 oct. pump gas w/out problem's.
