Comp 270 Cams Video
 

Sounds slightly different now that it's tuned but still pretty similar.

how much did it run you for those cams with install and everything

I scored a awesome deal since they were used from my Friend/Boss. He helps me out like crazy and does the work. I just play shop monkey and hand tools and clean up.

But I've seen the Cams new for $590 PLus you need Springs so add another $200 and then whatever your shop does labor for.

Comp says you should notch the pistons. For our cars we didn't have to. The Valves do slightly hit the cylinder, you can see faint marks on the piston. But it wasn't enough to bend/damage the valve.

wow that sounds awesome...wanna trade me cars?

your gonna be scrwed dude, your valvles are gonna be bent soon...just wait ;)

The other guy ran them for 15k, only had a few little makrs when he replaced his shortblock.

If they were to bend just gives me an excuse to get my fox lake 2s for my new shortblock even sooner. :devil2:

i need money

are the 270's notorious for bending or something?

It's not the camshafts that are gonna bend, it's the valves. They're hitting the top of the piston.

Yea i know that its called PTVC "piston to valve contact". My question is do the 270 cams cause it always, or does it just happen to people who dont upgrade their springs with the cams.

how much power was gained?

Yeah I'm very curious too.

ive heard it happen to alot fo people..it might have been the 278...but your cuttin it close man...and besides that CAN'T be good for the valves OR pistons

Yeah, I'd be less worried about the valves and more worried about knocking a hole in the piston, that's just me though.. being overly paranoid.

on the bright sound, it sounds freaking awesome man!

No idea how much power was gained yet. It has a mail order tune, but it should be on the dyno in the next month with some spray hopefully.

As for the valve I'm not worried about my valves or a piston I have a whole new shortblock in the garage and if I bent a Valve it would only give an excuse to get the Fox Lake 2s even sooner.

Not to mention they have been in for nearly 1000miles with no issues. AND he ran them in his car for over 10,000 miles.

thats fuggin retarded to do to your car - its goning to be all screwed up... and 10k miles aint long either

haha i cant stop watchin ur vid...i love that sound so much

and its making my friend with an 01 gt to get a CAM!!!! cause it sounds badass

Damn! That sounds **** hot!

holy hell that thing sounds sick!

Ahhh any piston to valve contact is not good, period. 270's should not contact if installed correctly. They need to be degreed to insure proper clearance. The Comp 278's will not clear without the pistons notched.

I totally agree. Whats the point of running those cams without the proper springs?

Also Comps springs are not much better than the stockers, Crower makes a good spring. Springs are a must with the higher lift cams, 270's, 278's VT 2's.

The valve would break way before it would push a hole into the piston. And the comp 270's wont hit if timed correctly from everything i have read. The problem is no one times them corectly. but its so close even timing it makes it close. Its a awsome cam. The best in my book for a daily driver nasty cam.

Also pretty good for making a mess in the engine bay and your wallet if your not carefull from what i have read.

If you must run 270's get adjustable timing gears, degree them or don't cry when you motor is fugged.

Everyone here is right, dude your motor is a ticking time bomb. I had the stage 1 comp cams and they need to be degreed when installed too. To many people read a cam swap article in Muscle Mustangs &Fast Fords or were ever and think there is nothing to it. Trust me I just got my car back from the shop cause I thought I knew how to install cams. Piston To Valve contact is not OK even if its only ever so slightly. PTV puts unneeded stress on the rods and bearings as well as damaging the valves.

just search modular depot there is tons of people who didnt degree there cams on the 270 and up models and have problems. I wont say its a ticking time bomb, just that you should really go back and retime them if its leaving marks on the pistons.

Only reason I say ticking time bomb is as soon as he gets in a few runs up to 6000 rpm's or higher one of those valves will let go. It might not be the first run or the 10th but with continued piston to valve contact somethings got to give. Just a matter of time.

Well yeah i would say soo too. I would really go back and tiem them again.
