this has probably been posted before. but what size cam do you guys have and what mods do you have done to your car. i wanna cam that isnt going to be to big or to small for the mods im doing.

Joel@

Try the new comp xfi cams. We have installed some of them. They have great driving charateristics. Idle very nice, run very smooth. What are the other mods you want to do?

mike1989

i plan on doing bolt ons and the cam but i dont want a cam that is going to sacrafice low end power but i still want to know that its there.

you're going to know that most any cam is there unless u decide to hide it with a tune or go with like a cc305.

i'm just running a hotcam with MAC mids, no cats, and open borla (the open exhaust helps) and u can definitley tell. i wouldn't have gone with this cam except it was an insane deal.

i know it's one of the smallest cams, but it makes some damn good torque numbers. i almost picked up a cc306 but now i may just do some head work and keep the hotcam in.

if i was to just buy a cam i'd definitley go bigger. probably like the cc503 224/230 or maybe an XE 230/236. depending on the lope profile, lsa, and more it may not be a big end cam even though it's got some pretty good sized duration.


here's a vid of mine just started cold and in open loop. it's idling around 1000 rpm in the vid, but when warm and closed loop it idles around 725-750. i don't have any vids of the lower idle since i wrecked the car about a month after that vid, but within a week i should have that motor/tranny into another body.

u can definitley hear it when it's warmed up and driving around. i've gotten quite a few compliments on how it sounds at red lights and meets.

personally, i'd go bigger, but don't be turned off if u find a badass deal. even with 3.23 gears and swapped to a 94 t56 my traction problems in first and second were just ridiculous. the low to mid range torque is very noticeable and pretty much flat.

Yes the 230/236 cam is a great cam to go for. It uses 1.6 rockers. Let us know if you need any help

Make sure you do all the other stuff necessary otherwise you will be wondering why your cammed car is so slow. I did a mild cam(208/221) in my Caprice a couple years ago having stock gears, near stock stall and stock manifolds/cats my best that year was 14.9. I now have mild stall at 2800 which dropped me to 14.1, then gears and better intake, 13.9, last night with the new headers and better weather 13.2. You might think that is slow but consider a raceweight of 4300lbs and it starts to sound pretty good, that is belton no icing the intake no "tricks" just bolton the slicks empty the trunk and run. Don't do a cam till the intake exhaust and drivetrain are sorted out. IMO most guys on the f-body boards suffer the age old problem of going too big on the cam it is a way to go fast but you would be suprized at just how fast a "small" cam can be some very quick f-bodies running cams smaller than the HOT cam.

i found this cam on thunder racing would it be a good one i know ill have to do other mods first but would i need to buy new heads or port and polish them.

63-07-305-8-112 Comp Cams "305" LT1 Camshaft, 220 / 230, .510 / .510 112 LSA, More aggressive with good street drivability and decent vacuum. Good midrange power.

The stock heads do leave room for improvement BUT are better than anything that came before them and can make for a fun car without porting. Good porting can however make more power. If a 20-30 hp gain is good enough for now then just do the cam if you want more now then consider porting.

Joel@

Thats a good cam for its time, but the new xfi cams are much better. Drivability will be better with a XFI.Slap some LTs on TB and cold air. Then get it tuned...you will be happy with that for starters.

Anyone care to share some links to actual performance improvements with the XFI lobes not just bench racing "better" claims. Not saying that is what Joel is doing just I see vendors plugging them and people talking them up and have seen VERY little about their actual use in cars out on the street and would just like to see some results.
I really hate it when things happen like the MSD cap and rotor and everyone talks about how great it is before any are out on the street.

Joel@

I have tuned both cams in LT1 cars. I have a LT1 camaro, and have had 3 of the comp cams(503,306,305) in my car over the years. I never had put a new xfi cam in my car,but I have installed them and drove them. They do react better to the fuelinjected car then the old ones. Hardly none,if any cam surge. I was really impressed. If I knew about these back then. I would of put one in my lt1.

My understanding is that these have just recently been released, I would just like to see some measurable results, feel is very important though as most of us spend a whole lot more time on the street than on the track.

i had the cc305 in my first Z28, and you could hear it and it made good power with stock heads. and i didn't have to spin to 7,000 to get it.
