Thoughts on a cam for a mild 460?

Engine is an otherwise stock mid-70's 460 with the D3VE-A2A heads
(restrictive exhaust ports). It's going into my daily driver '68 Galaxie 500
with a C6 (stock converter) and 2.80:1 gears. These are some cams I've been
looking at. Thoughts?

268H:
Basic Operating RPM Range: 1,500-5,500 RPM
Duration at 050 inch Lift: 218 int./218 exh.
Advertised Duration: 268 int./268 exh.
Valve Lift: 0.494 int./0.494 exh. lift
Lobe Separation (degrees): 110

XE262H:
Basic Operating RPM Range: 1,300-5,600 RPM
Duration at 050 inch Lift: 218 int./224 exh.
Advertised Duration: 262 int./270 exh.
Valve Lift: 0.513 int./0.520 exh. lift
Lobe Separation (degrees): 110

265DEH:
Basic Operating RPM Range: 1,500-5,750 RPM
Duration at 050 inch Lift: 211 int./223 exh.
Advertised Duration: 265 int./275 exh.
Valve Lift: 0.484 int./0.510 exh. lift
Lobe Separation (degrees): 110

Also saw this Lunati cam of the new "Voodoo" line. Thoughts? Is that
'hoodoo-voodoo' gonna be too much lift for stock rockers and valve reliefs?

LUN-61602LK
Basic Operating RPM Range: 1,400-5,700 RPM
Duration at 050 inch Lift: 219 int./227 exh.
Advertised Duration: 262 int./268 exh.
Valve Lift: 0.540 int./0.552 exh. lift
Lobe Separation (degrees): 112

A word about these later.

A good old cam, but...

This would be my pick. The new XE profiles are aggressive and give a wider
power band than before with better vacuum and response. Besides, I have
been reading your posts for a long time now. You are one of us, in that you
are always interested inn learning and trying stuff. You will build on
this, and this cam will respond well to future mods.

This cam profile is ancient. Don't bother.

Too big for stock stuff.


The D3 heads are great. The exhausts are not a big deal, and can be made to
flow almost as much as the C8-D0 heads by someone who knows how. Scott
Johnston is the master of the factory 460 head these days, and he did my
C9s. Yes, you can get 220 cfm from those exhaust ports.

That's his website. He posts everyday on the 460 forum:

Anyway, those heads are good.

Excellent, I thought that one looked pretty good. I think I'll go with the
XE262H. How should I install it though? Straight up? 4* advanced?

Thanks for the advice and sites. I've seen both of the sites and have
perused through the 385 N54 forums now and again. Seems to be a very
resourceful forum. Anyhow, I was thinking about porting the heads myself.
Just cleaning them up a bit and removing the exhaust bump, but decided I'd
be better off waiting to do that for antoehr time. I don't have the money to
do new valve springs/keepers/locks, rockers and machine work so I'll just
try running them as they are with the new cam and when I do have the money
to do the heads right I'll go for it. I've been told even in stock form this
thing will put a big grin on my face compared to the 302. Let's hope that's
true! :)

Cory

I'd go straight up.

You may not be able to run the stock springs with this cam. It's best the
get the whole set at once. Save now, build later.

Scott's website has porting info for those heads.

I'm using the Windsor version of the XE262H in my stroker. Great cam! Peak
torque at 3600rpm and very wide and flat torque band.
