I disagree with above comment CCrower may have some universal grinds but IMHO yhis is not one of them and neither are the 267HDP or 271HDP and Crower's lube saver lifters are a great product ...Crower use .005 for advertised?
" Just for the sake of comparison, here's Crower's version of the same profile. Crower Compu-Pro Performance Level 3 Camshafts 31240'
Not talking about high rate cams like Howard's "agressive" series
here are some targets for intakes lower or higher lifts options
@.006 @.200 lift 1.5
250 126 .454
252 126 .481
255 128 .478
256 130 .454
256 tbd .461
257 130 .483
261 134 .494
262 138 .475
263 136 .498
265 138 .502
267 140 .506
268 145 .494
The intake is going to determine your dynamic compression which is key for driveability, part throttel and under 3,000
you could add a column for intake close point
the .200 duration is before and after your iCL intake centerline- which is near your maximum intake velocity- which uou do nnot want to restrict with a one size fits all profile
so take your old school suggestion and plug it in
see how much more durration you have to run to get the same area and how much DCR you looseIt's not about top end hp- just spinning it faster can hide thar
It's power all along the curve where chevy cams suck
Read what UDHarold said about the differences in his cam designs ending with the voodoo serirs
he claims 25 HP
back when we were runing heads up wee'd kill for 5 hp, or even when running stock
I work for Crower and design these cams. That part number 31240 is a great cam.
Sooooo, it’s mostly a “How said what now?” reply then.Actually it's blind in one eye and over 90% deaf in my right ear. How's that grab ya? lol
Oh come on now! You know his drill line!And your cam recommendation is?
I have none. lol just keep it under 268.And your cam recommendation is?
rumble fais to remember that I did not list race grinds
Lunati chevy voodoo and mopar voodoo are exactly the same as far as "agressivness" goes
but if you want less than the street mopar lobes I listed get MP, some Crower, Some Engle
they will still give you more butt dyno than the 50 year old grinds- the old ancidotal favorites
here we have a couple of challanges
fist do the detective wor for asingle spring to replace duals, maybe beehives
a call to the tech line or spring list should do it
split cams
really depends on exhaust flows, manifold, headers, heads not as simple as it used to be
273
pick your intake duration- here we have very low compression , a not too high stall converter and 3.55 gears
and check against the rev range you are looking for 3.91 in a dart would be different
really depends on how and where you drive it stop and go, speed bumps , or wide open highway where you can give up some bottom end
Comp HE 268-H, 268 adv., 220 @ .050, .454 lift on a 110.
I have been using Isky only for flat tappet stuff, as they won't stock the austempered cores I need for roller cams. Isky is far superior IMO in both fit/finish and lifters...power is as good or better than anything else and I've yet to have any problems with their stuff...also run their solid roller cams and lifters is higher end builds with excellent success. I will say though, 300HP can be made with Comp's 275DEH cam.The typical number of pages for this type of thread is usually at least 3 or 4....... so let’s get some fast rate cam proponents on here to stretch this out a little farther.
I normally chime in with my std answer of “Comp 268H”........ but I’m going to mix it up a little this time around.......
Isky 264-Mega
Thanks, I had gotten my numbers mixed up along the way there!I know, I know..... what’s 2deg between friends....... but..... it’s [email protected]
Me too, and for the OP ..my favorite color are these.I thing the factory 340 cam would be a good bet.
I'd have to against the grain if I was going for a little more.
Howards and Crane have some very nice split pattern grinds available, one of these would be my choice.
It's your choice, I have no interest in choosing your cam.
I’m going to try out a new method for my next build.......
Open the cam catalog........ and with one hand put your finger on one of the cam listings.
Then....... with the other hand......

I’m going to let the horsepower spirits guide me.
Once apon a time a long time ago I ran a split Crane HFT that worked really well to the tune of 14’s in a 3900 barge. 218/226-.454/.480-112.
Like it so much I did it again in a beater 318 Duster w/3.23’s on stock tires. Had a hoot with the itty bitty cam.
Very nice, they always have , for Mopar.Crane has some nice grinds...
crane does
they also have white box in the catalog not identifief
remember Crane bought one of the big Detroit grinders
Crane has 3 series of Mopar lobes street to race only so does Engle, Crower
very few in the catalog
best to work with tech support if interested
back in the day they were smooth and easy on the valvetrain
johnny dart does the comp xe 268 hav around half inch lift? with commensurate area? how much duration @200?
