Anyone have any issues with these cams?

I have a 40 over 350 with a hydraulic lifetr cam and am pondering on whether or not I should drop it and put in a roller cam and lifters before i go through the trouble of puttin the engine.

 

John Lingenfelter for sure is one of my hero's. Had the opportunity to meet him introducing myself when he was racing Pro Stock Trucks and throughly enjoyed the conversation. I must have read his book ten times. His daughter is drop dead pretty and I feel real sorry for John Page @ 21st Century Muscle Cars for marrying her and having to wake up to that every morning. Poor Guy!

However.....Saying all that, his cams are somewhat dated but great if you want very good drivability and surprising good performance for the duration. If your into more of a stock think.....Super Cam.

If you more into a buzz....a lot better out there.

What's your poison today??

 

I agree with the above post. Although John's cams are good time has marched on. Go with a roller cam and look at some of the newer grinds.

 

Thanks fellas, I do know that they are out dated, and I am definitely going to put a roller cam in next chance I get.

But, for now I was just wondering if that cam would suffice until then.

I was sorta lookin for real bad vibes on them that might keep me from wastin my time before I install the engine.

 

Might want to mention what engine you have..... L98, LT1????

 

I don't really think this belongs in advanced tech. However, John's cams pack a punch because they are usable in the rpm range most street cars operate in. It jsut goes to chow you don't need a lot of cam for stock heads. Go with the xfi or lunati voodoo lobes to get more lift. I use Engine Analyzer Pro to design cams for my cars and some of the best combinations would surprise a few people.

 

I had a Lingenfelter cam in my original setup, 211/219 533/560 112LSA
383 LT1 with pocket ported heads and all the minor bolt ons etc. now here is my advice on the matter, the cam itself made a good amount of grunt down low, gobs of torque. I think in a stop light to stop light situation this setup would be hard to beat. Now with that being said, after about 5000 RPM the cam stopped making power and sort of fell on its face. It also made for a dissapointing dyno session, it dyno'd 336RWHP and 375RWHP with a rich tune. I know the dyno isnt the best tool for measuring performance but those numbers were not very impressive. Now I bet there were a few ponies left to be squeezed out but it just didnt make the kind of power I wanted. I don't know what your goals are or what platform your working with but the Lingenfelter cam is great for the street, it keeps you in the meat of your power band with lots of torque to spare but it is very mild. If your looking for something with a little more giddy up for the track or whatever i would go with a GM847 with stock heads. Just my two cents.

 

very true. decide on your goals for the car and cam selection will be much easier. Torque down low is a lot more fun than a car with lowsy torque down low on the street - at the track it is a much different story. Personally I look at the curves when selecting the best combination to get the most average power in the rpm range that I will use. Deciding where you want to spin the motor to is a good place to start.

 

The LPE 211/219 was my first cam for my 97SS ten years ago and I loved it. Great throttle response, good power and idled like stock. Made 350 at the wheels with MTI heads and shorty headers. If that is what ya want....

The problem is once bitten by the need for speed vampire, there usually is no turning back and you will probably outgrow the LPE cam quickly. Think I had it for three months before venturing into something larger, but I really did like the cam.

If it wasn’t for that damn vampire, my bank account sure would look better but afraid I’d be a pretty dull boy.
