do i need to get heads to support this either of these cams.
230/234 .592/.592 111 LSA - 2200-6400 RPM
236/240 .592/.592 112 LSA - 2400-6600 RPM

which one would you recommended

if i dotn all i am gonna do is get lifters adn springs and the cam and throw them on the car for now until i do my 408 ltx sts thanks guys

 

heads NEVER hurt and i think ud see a substantial gain is u atleast had work done on ur stockers not to mention more work done on good trickflows, AIs etc. id do head work

 

both have a decent amount of lift for stock heads likely get choked on the big end.

personally for stock heads my favorite's always been the cc503 which will have better street manners, gas mileage, powerband than either of those imo

 

if you've got the coin might as well get some heads, if you do I'd go w/ the 2nd cam
if you don't I'd go w/ the 1st cam and your gonna need more then just lifters and springs

 

1st one is comparabel to the cc306 supposedly

not enough coin fro the heads adn i jsut want a cam car. what are specs on teh 503 does it hit hard ( can you hear it cammign from hail) and what all do i need to do to run that one i am looking for my best best fro jsut a cam/ tune only car its a six speed to thanks guys

 

cc503 is 224/230 .503/.510 (on 1.5 rockers) 112 LSA

it's not gonna cam as much as a cc306 but it's not exactly far off

here's a vid of my car when I had the cc503

OMG another one of these dumbasses

 

do the first cam you listed. It will be fine with stock heads. make sure to tune the pcm after.

 

Before I say anything else, how high are you willing to spin your motor?

Stock bottom end correct?

 

And i thought a 226/230 .565/.565 was gunna be massive on stock heads...

 

It will run fine with stock heads, but if you get them ported, or buy some aftermarket and get them ported, you will see large gains.

 

i like your quote big deal i ******* misspelled some words go cry about it

as for me spinning the stock bottom end i would be willing to turn 6300

 

what was all doen to that car to make it sound like that any motor work? were would i get that cam new thanks

 

He wasn't really focused on the spelling...lol

 

Uh yeah.. yoooer spelign raly hsa nothgni to do wit ur dumm asserry

 

i wouldnt run any one of those cams on a stock headed car. both will need heads gears and a 3200-3600 stall if your auto. you will need to rev the motor pretty good to get the power out of those cams. if you already have them in your possesion and absolutely need to put one of them in id run the first one.

 

If your only willing to spin to 6300, both of those cams would be a HUGE mistake.

They even show powerbands greater than 6300 so I have no idea why you are considering them. Keep in mind if a cam has a powerband up to 6400 you still need to rev it a couple/few hundred rpm beyond that for an optimal shiftpoint. You should look at a cam that has a mid 220's intake duration MAX with your 6300rpm limit.

With that said you could run either of those cams and keep the rpm's under 6300rpm but you will have a car that sounds badass yet gets its *** handed to it by cars with smaller cams that are setup properly. It's up to you but you would really be much better off with something smaller IMO.

 

You don't want to just do springs and lifters. You'll possibly want to do pushrods also, and definitely 1.6 rockers.
Think about this: You'd be basically gutting the heads completely. You might as well take the heads off (only another 2 dozen bolts or so) and get them ported locally. There's a guy in my area that will port a set of heads for $100.
With a cam and all new valvetrain, you're really limiting your potential for power gain by sticking with un-ported heads.

 

$100 port job? LOL

 

Haha and then another grand or some to send them to someone else to fix them and do it right.

To the OP if your dead set on stock heads and only spinning the motor to 6300 then you really should look for another cam and do not go with one of the ones you listed
