Comp 101400

Havent heard anything on these cams at all besides there big...........big big. How compareable are they to a set of 280's? I'm needing a decent set of cams that are going to take me to 9k without dropping off air flow. I have a completely built bottom end(bs removed, ross/eagle, balanced crank) built 1g head(crower springs, JAM +1mm valves, ect ect ect) JMF Race SMIM. How well will these perform in my application? Idle doesn't matter one bit to me, for I know these things are flat and are going to cam hard.

You will need more spring then what you have because of the ramp rate. FP states they need to have a dual spring setup. I went with Supertech and they are more then enough.

crower may be enough. see:

This is w/ manley singles and titanium retainers plus these exact cams... I suspect the lightening of the retainer mass has a great affect on what springs are "enough".

FWIW, i've run manley singles and FP2Xs (ferocious ramp rates) to 8500 rpms for almost 2 years now. Yes, ramp rates and rpm level are more important than anything, when it comes to spring choice, as there are very, very few grinds out there that actually could bind the stock springs...

A note: stock SHIMMED springs were used for years as upgrades by the 'greats' when there were no aftermarket upgrades...

alright I think that settles it.... I'm going to go with a set of 101400's They sound mean as all get out.

I hope I havn't misguided you. . . I don't think you should rev to 8500 rpms w/ the 101400s. . . if you have crower springs you'll have insurance to go to the stock redline in my opinion. But remember, that you won't get the full out of these cams unless you infact do raise the rev limit. You will be adding mor rpms to your power band as these cams peak high. As is you can get by jsut fine at a stock rev limit.

As from what I've been told the crower's are actually stiffer than the manley's. and if something does happen then I'll just got with a set of SI's
