what is the powerband of this cam and can it be used with a stock computer?

 

Search, search, search, search, search!

 

what do you think im on here trying to do? i thought the purpose of this website was to see what works in cars, and what doesn't through other persons experiences? if you dont know what your talking about, dont tell me to do more research. please, if anyone has any experience or knowledge as to how this cam works in a 350 tpi engine, let me know, i would appreciate it a lot

I'm not sure on the powerband but I'm going to speculate it would be similar to the LT4 engine. But, the stock TPI system loses steam short of 5Krpm so it wouldn't utilize the entire power band of the LT4 cam anyway. I'm pretty sure it won't work with the stock computer tune. I know there are others on here who would know this better than I. I'm sure they'll chime in soon.

thanx gene, yeah i know the tpi is a low end monster, i just figured id start with doing a cam and head swap, then doing a mini ram, or something of that nature down the road, followed by bigger headers. i just want to make sure everything matches up correctly, when i finally am finished. the goal is too get the hp and tq #'s as close as possible, with a very flat tq. and hp curve, or the widest powerband possible. but im taking my time, just figured id do a little research ahead of time

 

Not true. The LT1 F&Y body cams and the LT4 cam are very similar. The LT4 cam lift looks bigger because its advertised specs are with 1.6 rockers. There are alot of members running those cams on here because they can be found used for very little $.
They work well with stock tune because of the mild specs ,plenty of vacuum.

Tmviper, formula_novice was telling you to use the "search" function for this site not telling you to research more before you came here.
If you enter "lt1 cam" or "LT4 cam" in the seach function it will come up with enough threads to keep you reading for a long time.

Some will tell you the LT1 or LT4 cam is not enough of an upgrade to go throught the trouble of swapping it in. If your car came with the lame "peanut" cam the LT1 or LT4 would be a decent cheap upgrade. If you have the bigger stock TPI cam then those cams will not really be much of an upgrade. Hope that helps.

 

If you are planning on swapping heads and have the budget for a new cam there are better options that the LT4(production) or LT1 cams.
Something from Comp cams,TPIS, or the LT4 HOT cam would be better. Those won't work with stock tune if you are SD.

 

He wouldnt have the "peanut" cam with an original 350 TPI.

If this engine is stock there are other better ways to spend your money than on a cam swap. Start with the exhaust, a 3" cat-back is excellent. Then get subframe connectors. Headers and a high-flow catalytic converter or two are also mods you should do before a cam swap. Also, since you have to remove the intake manifold to change the cam, its very highly recommended to get an aftermarket TPI intake manifold and install it at the same time as the camshaft.

The stock LT4 camshaft ( NOT the LT4 hot cam ) has slightly more duration and more lift than a stock L98 camshaft, so it will give you about 15-20 more horsepower and torque at the flywheel, not at the wheels.

 

Sorry missed that he had a 350

 

I`m running that cam with 1.6 rockers.This was my first engine build and I got the cam for $99.99 new.If I had known more I would have gone bigger like the hot cam,but I hadnt found this site yet.The power over my basicly stock 305 to this cam in a 350 was a great increase.For you you may get bored with it faster than me but right now this is the fastest car I`ve ever owned(not saying much).This cam makes 330hp at 5800rpm`s in the LT4 camaro,That is with larger valved heads and better intake.I blieve with the 1.6`s and intake upgrades(HSR) It could be a good cam,but there are better.It will run better with a tune.Ibelieve a MAF car will handle it better than SD without a tune.Not sure what year yours is.Since it is a production cam it has a great idle and I still get good mileage.It really depends on what you want your car to be and your budget.

 

i wouldnt waste your time with the lt4 cam, the LT4 hot cam is a good cam, this cam makes 450hp with the LT4 kit for Lt1's etc.

LT4 hot cam is 200$ from scoggin.
specs
218/228 duration .495/.495 lift with 1.5rr, .525/.525 lift with 1.6rr
power band is 2000-6000rpms. but thats too much for a TPI, unless u upgrade it completely to a high flow, port plenum, highflow runners/base, so that it pulls to 5500. its a GOOD cam. some say u cant use it will a stock tune but ive seen it done with vortec heads/base, edelbrock runners, 1.6rr, 24lb injectors, everything else stock on a 87 350tpi and it made 355hp and 423 tq. a custom tune would have helped and some porting to the intake and a nice LT exhasut would have given it a bit more Tq/hp and thats what they stated.
i purchased this cam for my 383HSR im building but i said screw it and went all out so i got a compcams XFI280 and will prob give me an extra 30hp over the LT4 hot cam.

 

the lt4 cam works better with a diff intake like the HSR, its powerband is higher and tpi's is lower. The lt4 is a good cam, its really not that big compared to others, id go bigger for a 383

 

i understand what your saying, i already have headers and 3" exhaust, 24 lb. injectors, afpr, 1.6RR', airfoil, k & n filter, a full msd setup, & hotchkis sca's. im leaving the bottom end stock, oil pressure is good, 97k on it, want to start with a cam and head swap. i will leave the intake upgrade for later though, b/c it is too much to do at once, if i have any problems, i want to be able to pintoint it, and its expensive all at once. once the cam heads and intake are done, ill upgrade my headers and y pipe, being that i have shitty flowtechs that i got for free. oh yeah, i was talking about the lt4 hot cam with a 218/228 dur @50, and .525/.525 lift. its either that or a step down to a crane cam with 214/220 dur at .50 and .482/.495 lift. in your opinion, which cam better fits my needs?

 

I have the production LT4 cam in a 305 TPI and LOVE the way that it runs with the LTR TPI manifold on it. Crisp throttle response, TONs of torque, good fuel mileage and a smooth idle. It should have been in the TPI car from the factory!

 

yea i kno thats why i sent it back and went with a comp cams XFI280 with 230/236 .567/.571 and 113 lobe.... im expecting alil beast

the crane cam will prob be a better choice over the LT4 hot cam bc the shorter duration will give u more lowend and decrease the peak power RPM. u should be calling them to see wat crane/compcams recomends for your application... there might be a better cam than u choosing.

 

Your question didn't state anything about wanting "personal experiences". All you did was ask a question that has been answered many times! You cannot tell me that if you search for "LT4 cam" no relevant information is returned.

 

my bad, i thought you were bein a ****. i have met many people in my life who think that they know everything, and they dont know anything. i apologize for judging you.

 

No problem.

Best of luck with your project!

 

AW,HOW SWEET!
