330 cam

330 cam
Hey guys, I feel like an a$$h0l€ just saying this, but I just recently picked up a 64 Jetstar 88 with a really healthy 330, and it runs very well. The car is really cool but it is uncomfortably stock... Has anyone thrown a real lopey cam on their 330s and does it even make sense to do on a 330?

My opinion is no. If your object is to drive the car for enjoyment, over-camming it will make it less drive-able. Your opening a can of worms. So basically I am saying, if it isn't broke, don't fix it and when and if it needs fixing, go with a stock grind. Jmo.

I put a sort of lumpy cam in my 71 Cutlass 350 with everything else stock including 2.56 gears/stock torque converter/exhaust manifolds, etc. What a mistake! It only idled bad- terrible performance. A absolute dog. I think that is what you would have if you just put a lumpy cam in your otherwise stock 330. I ended up going back to a stock cam myself. Now it idles smooth and accelerates as a stock 350 should- not a race car for sure but nice and smooth as Olds intended. Personally I really like the Jetstar 88 cuz it has the more"modern" V8 than the 394 and no slimjim. I would enjoy it as a nice cruiser....

Installing a cam like you want just to get the rowdy idle is called being a poser. Educate yourself as to what the implications are.

I'm sure you can find a cam that will give you a bit of a lumpy sound without sacrificing all of your driveability. Check with CutlassEFI to see what he recommends, but to take advantage of it you might need a higher stall torque converter. You could do a lot worse than adding the cam, headers, a higher stall converter, and a TH200-4r trans. That will give you a lower first gear and a higher stall to get you closer to the power band of the newly cammed engine.
Just the cam will give you all of the problems listed above, but if you make some systematic changes to take advantage of the cam, you might be able to have your cake and eat it too.

Do you know which 330 you have, is it the low compression 2bbl version with 245 HP or is it the high compression 4bbl 290 HP ?
What is your exhaust setup ? If you have the 290 HP version, dual exhaust should help.
The 2 speed is possibly the biggest hindrance to better acceleration, if that is the issue ?

It's a lot of work, time and money to hear a blip, blip when idling. Put a fouled spark plug on each side of the engine. If you like the sound, mission accomplished. The car will be harder to start, less gas mileage and not be much fun to drive, just as if you"over-cammed" it "but" when you get tired of the un- drivability, just put in 2 new spark plugs and "enjoy."

This is why I asked the OP to describe “lopey”. If he’s looking for crazy then yes you are all correct.
However you could get a bit of a lope with a smaller cam on a tight lsa. All depends on what he’s looking for.
