Jsut wondering if anyone new what the best and biggest cam i could get for my 91 camaro rs with a 305 tbi engine. I have 80 series flowmaster with no catalyc converter and a jet performance stage 2 chip. Dont know if that will efect anything but just wondering Also would like stay stay around 125 dollars if possible.

IMHO a cam is not worth it for you yet. do some other stuff first. just thoughing a cam in will not give you the gains you want. first you need to open up the intake and exaust, you need a good intake, 2" bore TB, and headers. after you do that, you really should learn how to tune it yourself.

 

Dewey is right on. You need to have your car ready to accept a cam. This requires everything from intake to exhaust and more importantly chip burning.

 

what i did was open the exhaust and also the intake tract first. then it was clear to me the cam is the shortcoming as the results were not as good as expected. so come spring the final piece of puzzle falls into place . comp cams 224/230 @ .05 114 LSA

 

224* ??? 350 may i assume?

 

yes

 

i was thinking to myself...

224* that is going to be one hot CF 305

 

I WAS GOING to put a 230* @ .050", .480 lift cam in my 305. Then I woke up and decided since it was pulling a brick @ 70 mph and 1700 rpm that I might need less cam. Also had to pass smog. The 204*, 214* that is in there now runs great though. Lots of low-end and midrange torque but still pulls easily to 5,000+. I often wonder what it would do with the extra 50 hp. When I build my 334 for it that is the cam I am using and backing it up to the originol rebuilt 700r4 and 4.10 gears.

If you want a torquey cam consider either the Federal Mogul CS1014R that I used or a comp X-treme 256 or one of their extreme marine-4x4 grinds.

I also agree that you are not ready for a cam yet. You need headers, good intake, know how to burn chips and tune efi, right gears, better heads etc.

 

yeah, 204 should give you a good torque feel, but not die like a stocker. i am putting a 210/218 .492 .492 112 UltraDyne cam in my 305. we will see how that performs Harold from UD says it will pull to 6400 if i want it to. being that my shortblock has 180k miles on it, i might retard the cam timing a couple of degrees and move my powerband down just a hair.

 

ronny, thats the cam thats in my engine that im dropping in soon.

If you want more low-end torque you advance the cam not retard. Retard raises the rpm for peak torque making it pull like a bigger cam. Advancing it makes more torque down low, increases idle vacuum just like a smaller cam.

His car might be needing an LT1 cam after he get it ready.

 

i meant advance, what i am thinking, and what i type are two diffrent things sometimes....

BTW, tossed an extra UD cam i had lying around in my car this weekend, specs are

206/216 .447 .447 112

was a nice weekend upgrade if i may say so

 

That cam is real similar in specs to the Federal mogul I tossed into mine. Mine runs great.

 

I believe most of Comp Cams street grinds have 4 degrees advance when you set them dot to dot, marine about 2 double check and ask staff as I did on particular grinds.

Seems to be a lot using Xtreme grinds, curious how they work on TBI motor, but I believe Oval track use 500 CFM TBI's with what 400 HP, even though I see some wanting more CFM. Running about 590 now, and I believe injector spacer will give me around 20 CFM more.

May upgrade 212-218 444 lift 114 LSA cam, so I am glad to see there is hope to find a cam that works and runs better then limits I was told to use/ need more learning on chips thought as having them done will not cut it. Like to run something around 268-280 with 470-480 lift, using 1.6 Comp Roller Rockers.

May also change out 180 Edelbrock 3701 TBI manifold to a non 180/dual plain manifold, just a few thoughts. 40 over 350, 9800 miles, balance, bored, ARP rod bolts, resized rods etc.

If this does not work, I guess it's time to go STROKER!
