cams?????
Ok guys.. I guess I will have to send the cam i got back cause it seems that its not a good choice. I really need some help with this. My mods are listed below. I want a cam that is going to make the car run alot harder but I also know that I am limited in my fuel supply. Someone with alot of knowledge in this department let me know what is a good cam that i can really feel a difference with not just on a time slip.. I am cam retarded so i just need some help from the car brains... and part #'s would help alot too.. thanks
*Don't panic!*
There is a solution!
I can't make the decision for you, but I have a Crane PowerMax 2030 in my engine and it works fantastic, but it is a pre-1985 350 CI and the cam is flat tappet.
This first link is to the Hydraulic Rollers:
http://www.cranecams.com/master/apps/chevy37.htm
The Hydraulic Roller 2020 by Crane is probably the best application.
That is probably the best cam for your car. Scroll down to the 2020.
194/204 111 sep 407/429 lift.
This second link is for the Flat Tappets:
http://www.cranecams.com/master/apps/chevy5.htm
The PowerMax 2030 Flat Tappet.
204/214 110 sep 423/446 lift.
Those are MY suggestions. There are steeper cams, and most of them are a question of what you want. I hope I helped you out.
Believe me, you will notice a difference!
NOTE: 1988-98 Chevrolet 305 and 350 V-8 engines (and some 1987 350 V-8 engines) use a different configuration camshaft core than the 57-87 engines and cannot be interchanged.
Since 1975, General Motors divisions have exchanged engines throughout different models. Be certain of exactly which engine you have before ordering.
I know for a fact that the 2020 Hydraulic Roller will work fine with your stock ECM/Chip.

Thanks alot for the advice and as for what kind of cam I am looking for... I want a cam that is lumpy enough to let people know it has a cam... now i know i cant sound like the guys at the local car shows that sound like they are going to quit running if you dont give them gas... but i do want a little thump.... i just dont know if this is possible since i have the tbi setup.. I looked up 3 cams today for roller applications so all these are roller cams.. let me know if any look good as far as numbers go..

Sound.
Hmmm. My car does sound like it has a cam. I think the ones you are talking about are just simply too much lift.
Let me find it.
Duration @ .050" 232int 234exh
Advertised dur. 292int 300exh
Gross lift 1.5 rockers .490"int .490"exh
Lobe center 106int 110exh
That was the Blue Racer/Wolverine cam I had in the engine before. No go. I just ended up fouling up my spark plugs and had no vacuum.
I know that cam was way too radical for my computer.
Hope this helps you.
BTW you can look at the 2031/2032
The 2031 is about the upper limit for emissions.
The 2032 is a slightly higher lift but is not emiisions ready.
2031:
208/214 @ .50 112 sep. 438/452 lift
2032:
214/220 @ .50 112 sep. 452/465 lift
The idle of my 2030 flat tappet is very wicked! Yes you can tell.

Oh yeah!
Stock L03 cam:
Duration 179/194 @ .50 109 SEP .350/.384 int/exh
Even the 350 TPI had....
Duration 202/207 @ .50 114.5 SEP .413/.428 int/exh
The Police PKG had: (Again TPI)
Duration 194/202 @ .50 112 SEP .383/.404 int/exh
This might give you a good idea what was there in the first place.

I just put in a Crane 2031 roller cam and love it! My mods are in the sig...
Low end torque is unreal and she pulls hard to 5500 rpms. Still running stock exhaust and heads (only mods to the heads were a 30* valve seat instead of the normal 45* seats).
Also, not running with the Fireball HI-6S box... just the coil.
As far as sound, it's VERY slight lope to the idle, but not much. Maybe once I open up the beathing of the enigne, she might lope a little more.
Later,
Mike

well the 2031 seems to be about the limit to what i can use in my car.. if you are using it and it works great then i dont see any reason it wont work for me.. the only problem now is that when i went to jegs site they dont have the same part #s as crane does on their website.... I need to know who can get it and what the part # is..... thanks guys.... If anyone knows any reason not to get this cam please let me know now cause I really am dumb about this stuff......
thanks
thanks
Trending Topics
Jeg's part number is 270-104225
Summit's part number is CRN-104225 (Summit is currently on back order).
Both places sells them for the same price.
You'll also want/need vavle springs:
jeg's # is 270-99848-16
Summit is CRN-99848-16
Again, both places have them for the same price. With these spring, no mods to the heads are required....they fit in the stock vavle spring pocket.
Just a little FYI about looking up parts online at Jegs and Summit: Both places use the manfacture's part number as their part number with an added pre-fix that corresponds to the manufacture of the part.
Take the parts listed above, the '270' pre-fix for the cam and springs is JEGS way of showing it's a Crane Cam part and the rest of the number is the actual Crane Cam part number. Summit uses some form of the manufacture's name as the pre-fix. CRN is for Crane Came, PJJ is Pete Jackson, HLY is Holley, etc...
This makes is easier for doing research on a part. I first go to the manufacture's website and research everything there about the part which I looking for..specs, part #'s, what else it all needs, etc... Then I'll just goto Summit or Jegs with the part numbers and punch them into the search field and the part pops right up. None of that browsing the online catalog stuff.
Hope this helps you!
