Ok, I've finally narrowed down my cam choice......which one would better suit my futu

[maverick0716]

The title is supposed to say ".....future combo" by the way....I messed it up

1. Comp Cams XE270HR
Specifications:
* Advertised duration: 270 intake/276 exhaust
* Duration at .050 in.: 218 intake/224 exhaust
* Gross valve lift: .512 in. intake/.512 in. exhaust
* Lobe separation: 114 degrees
* RPM range: 1,800-5,800


2. Trick Flow Specialties Stage 1
Specifications:
* Advertised duration: 275 intake/279 exhaust
* Duration at .050 in. lift: 221 intake/225 exhaust
* Gross valve lift: .499 in. intake/.510 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 2,000 to 5,500

My combo will be a Holley 4160 carb, Edelbrock Performer RPM intake, Edelbrock Performer RPM cylinder heads (1.9 intake valve) with either crane or comp cams roller tip rockers.....and one of those two camshafts. It will all be assembled at the same time, I'm just collecting parts right now.

have you talked to ed before you buy a shelf cam?

I don't feel like paying almost $450 candian for a camshaft that I have to have imported from the US.....which means I'll get raped by customs on duty fees and taxes. So I bet it would be almost $600 cdn when its all said and done. If I lived there, I might consider getting one.

I'm a Comp Cam's Man, but the spec's of the Trick Flow Cam, seem a little better matched for your combo. Really you could go either way as they both would work fine. It's a matter of preference.

Dude, go with the bigger cam. I'm assuming this is a 289/302. I've got a crane cam (PowerMax 2030, 270/276 duration, .533/.540 lift) in my current mustang that almost matchs the XE270HR. Its great for my current setup, which is ported stock heads and manifold. Gives it a slightly choppy idle too, which sounds awesome with my 2-cham flows and O/R h-pipe. With the higher flow capacity of your setup the bigger cam would only enhance to designed power curve of the combo. The edelbrock camshaft for that combo specs in at 290/300 duration and .500/.520 lift. The biggest thing the 2nd cam has is the tighter lobe sep, which will give you better mid-high power, but the duration and lift isn't so radical that you're going to lose much, if any, torque by going with the bigger cam.

Why are you limiting your cam selection? Lunati has some good numbers.

51014
284/292
218/226
.500/.510
112 deg lobe sep
2500-6000

51027
276/280
218/222
.509/.509
107 deg lobe sep
2000-6000

51025
284/290
224/232
.535/.544
112 deg lobe sep
2500-6500

You can compare the int C/L, lobe lift and valve timing events HERE if you're interested.

Thanks for the info....there's a couple of cams in there that catch my eye. Like the one for the Systemax kit. Almost like the e303 but with more lift.

What I really want is a cam that will match good with the heads and intake, but that is also good for a daily driver (reliable). I'm also probably not going to be taking it past 6000 rpm until I do a full rebuild down the road.

Comp has the XE270HR with a 112 lobe sep also, I would go with that if you plan to stay NA, I just installed this cam but havent started the engine yet

Cam is designed for use with 1.7 rockers also at .544" lift...with 1.6's consider the XE274HR
