I am in the middle if a cam swap and found a nice comp cam. cca-54-472-11 243/259 .624/.624 this cam seems to be a good cam. Can i put this cam in without flycuttin my pistons, i know with the MS4 cam u dont and thats a .649 lift. The car is stock.

Ms4 cams are a hit and miss. Most cases I've seen flycutting is necessary. That comp cam is way too big for a stock cubed ls1 imo.

i am new at ls1 so help me out a little, why is the comp cam too big if the lift is smaller the the MS4.

You really need to look at duration when it comes to piston to valve contact. And the exhaust duration on that cam is too much for stock heads

lildirty2004

oh ok thanks, i didnt know that. so MS4 cam kit it is. that cam kit is $700, has anybody put their own MS4 cam kit together that was cheaper. i even call texas speed and with the MS4 cam they give u springs rated at .650 lift and the cam is .649 lift, why not give us the springs rated at .675 lift.

KevinR

Man, I would just get the kit that they offer you. It's not a good idea to go "cheaper" IMO. Do it right, the first time.

Also, the biggest cam isn't always the best cam. What other mods do you have?

lildirty2004

longtube headrs, ls6 intake, 85mm throttle body, 85mm slp MAF, TB bypass, Ram HDX clutch, 4.10 gears, and smaller pullies.

The ms4 is an all out badass race cam and even w/your mods will not
have great drivability below 4000 rpms.....if thats what you want have at it

KevinR

Even if you decide to go with the MS4, it's STILL a good idea to measure ptv clearence.

Not true. There are plenty of people running that cam in their DD. It all depends on how good his tuner is.

with stock 241 heads i would highly recommend the torquer v2 cam, easy on valve train plus runs hard!!!
u don't even need to rev it to 7k rpms like the ms4 cam

lildirty2004

do i need to run a db roller timing chain, i wont be making that much hp, or will a single due for me

LS2 single chain is fine. I would run a lil smaller cam but to each his own... On my old 346 I thought a lower 230s cam was just about right....nice bottomend and carried good power to 6500+

lildirty2004

what will be a good oil pump, melling 296, slp which is $180 wow, or the ls6 ported

lildirty2004

and also i know u said ls2 timing chain, so any ls2 timing chain like trick flow ls2 timing chain

do not use the comp cam that u mentioned it is way too big and not only have ptv problems but your car would be a dog
a ms4 is good if you dont mind being extreme and are ok with a not as good driveability
but if your not, go with a 228 through 234 sized cam good power and good driveability

maybe look into the tv2 cam or the f13 cam ..both work well dd and give u good gains

lildirty2004

i am done wit my cam swap, now i am stuck on intakes, i was looking at the BBK intake but the power band is from 1,000 to 5,800, and the holly is from idle to 7,000. and i have the ms4 cam which spins to 7,000, and i will be swiching at 6,500 what will be a better intake.

BBK intake is a waste IMO, LS6>BBK

get a FAST!
