You know my car set-up. How does this cam sound? I know I have a 305 but I'll be swapping to a 350 in the winter. If it helps you out with your decision I'm only swapping the short blocks. Nothing else. Maybe I'll have the phlenum, runners and manifold ported. But that's it. No headers Can't afford them. Unless I find a cheap set somewhere or a good deal. The A.I.R tubes add to the cost.

How much does jegs have this going for in your catalogue?

P.S. I'm also sending you a PM.

Everyone's input is welcome. Slade1 just happens to know how pathetic my car runs and has a Jegs catalogue handy.

 

The stock heads will support that since this cam is a direct stock replacement part.

If you are going for the 350, I imagine no real issues on it.

I'd recommend porting all the top end parts as it is a 305 part (well even the 350's got the same intake) so it'll be suffocated. Also having those log headers will really hurt your performance though. If you're gonna have the engine out, may as well put in headers... it'll only be a pain later with the engine in the car...

You should be able to make more power from the cam though than a standard L98 as the lift is higher than the stock part.

Jegs says $259 for the part. What were you quoted over here?

 

thats the cam that i have been running .

i dont like it at all!!!! i just am not seeing the power that i wanted. i wish that i went with a better one.

i am hoping that my cat back and headers will help it out. other wise i will be swaping it out. i am also running 1.6 rockers to help the lift.

just my .02

if the headers dont work out and you can wait untill winter maybe i could sell you a used one

 

The key words on this cam are stock replacement part... Its better than a standard 350 cam, but still much like the 350 cam. I wouldn't mind taking that cam off you Trigger... its a good cam for my car and should be pushing me (with headers) into 92 zeddar's territory for torque and power.

 

no the key words is will it will work with the stock computer. it calls for a higher stall in the trany. the duration is also longer than stock.

slade it is a roller cam in you engine a roller also?

 

Yep it is. Only handicaps on my car are the peanut cam... low flow heads... intake... tbi... headers... geez its no wonder every little mod is worth a lot...

 

Using that cam with the stock springs would be bad. The stock springs are garbage. End of discussion.

I have yet to see anyone run a decent time with one of the Crane "Compucams". Your best bet is to use a cam that was designed to be an EFI cam from the beginning. Not a carb cam that was modified so that an ECM won't gag on it. EFI cams generally have minimal overlap and steep valve ramps. TPI engines like cylinder pressure which is what those things promote. I'd suggest the LPE "216" cam.

 

That cam is for an EFI. That's why I recommended he switch to 1.6 rocker arms though, springs normally done too in that kind of swap.

The heads can take up to 0.480 lift stock... but don't expect any extreme gains from stock low flow heads...

The most gains will be made if intake, cam and heads are matched. Without that, you'd probably see only a portion of the possible gains from that cam. That's why I'm thinking trigger's combo didn't give that boost he was hoping for... oh well live and learn... You also need a good chip reprogramming to account for severe changes to cam, heads and intake else it'll only flow what it was designed for on EFI systems...

 

That cam is an old grind from the mid '80's when EFI tuning was in it's infancy. Adding 1.6 rockers to that cam in a 305 would be bad. You'll need new valves right after it's started so buy them before hand. The stock springs may take .480" lift on paper but they won't be happy when the cam is in the car.

But once again, what do I know.

 

How does a 260H cam by High Energy sound to you? 440 lift so not getting close to 480, but still thinking if I did that I'd still go with 1.6 rockers with springs...

If all else fails, the LT1 cam is always an option for my car... that is definitly more EFI friendly and modern and should give a definite boost to boot too.

Quick q accelz, you ever build with stock heads up or you just chuck them?

Palric.. need advice in here quick.. did your heads survive the hot cam you put in that 13.9 tbi beast?

 

I had my stock B2L heads rebuilt using some good stuff. I had a 5 angle valve job done, back cut valves installed, and had the spring pockets opened up to around 1.48". I sold them before I used them. I think the stock TPI heads are capable of getting a properly set up car into the 13's. As far as cams go, have you considered the production LT4 cam? It's slightly wilder than the LT1 cam. The High Energy cams are old grinds as well. My fav's in the Comp book are the extreme energy line. Now those are modern grinds.

 

LT4 production cam...........


https://www.spoperformanceparts.com/...2604&CATID=826

 

As far as the xtreme energy line goes... the ones the recommend for 87-up cars are at minimum 487 lift... those will force a definite retooling of the heads for sure for my car...

The LT4 hot cam I've looked at and that has a 500 lift lurking in the profile... I'm really not intending on rebuilding my stock heads. I just want to do a cam change pretty much.. at worst intake and headers, but cash flow not quite there yet.. getting the heads off my car left my right hand disabled for a week last time I did it...

 

Lol, no man, not the "Hot Cam". It's the cam the actual 1996 LT4 'vettes had. It's similar to the LT1 cam but would probably produce better results. Check out the link.

 

I just did... would that need new valves or not though? I'm all for changing rockers and springs.. but if I gotta go after the headers again cuzI have to get the heads off I think I'll have nightmares tonight...

 

New valves? Why? The lift numbers given are with a 1.6 rocker. The lift with a 1.5 rocker would be .446/.450. A production GM spring would tolerate that cam with 1.5 rockers providing they are from a roller motor.

 

Man must have been tired when I clicked the link.. didn't notice was the 1.6 numbers... yeah, that cam sounds a lot better. I always thought that the LT4 cam was a hot cam, didn't know they had a LT4 Hot and a LT4 mild... don't know much about the LTx engines really.

What's the average price those cams go for? I may just pop one in for the hell of a good boost.

 

Hey Slade1,

I ran a pretty radical roller in my TBI305. I think the only reason it worked is because I had just as radical an intake/EFI and exhaust setup. I did not do any work to the heads other than replace the factory springs with Comp Cams conical HD springs which were rated to .550 lift. I was going to install some AFRs but then came baby #1 and the rest is history...

The cam I installed was 217/225 and .480/.505 and then I installed 1.6 rrs so my total lift was .505/.525. But the LCA and overlap was all wrong for this cam (I think 109 degrees) and had I known better at the time I would not have used this cam it did not idle worth crap and I spent over $500 USD in chips from Ed Wright (10 years ago) trying to get a combo that would work. It rev'd like a banshee though. It had way too much intake duration. Make sure your LCA/overlap are VERY streetable the TBI is way sensitive to vacuum. AcceldZ probably has the last word on that. I put about 20,000kms on that setup before the bottom end started knocking it saw 6500rpm too many times.
IMHO if you are going to cam the TBI better do the intake and exhaust first or you are wasting your time.

Hey 88redxtsy,

I think 214 degrees on the intake lobe is too much. There are alot of opinions out there on this. Mine is this -- the TBI and TPI 305s do not like alot of intake duration. From what I have done/seen you can pour on tons of lift and exhaust duration into your cam but intake duration and overlap is critical.

To me 214 degrees is TOO much for a TPI 305. FYI I would not go above 210 degrees. When it comes time to cam my 305 ideally something along the lines of 210/218 and .500/.500 with about 114 degrees would do it. But then streetability is big with me.

IMHO, if you want to make power with the TPI 305 it has to be primarily through heads and exhaust. Of course this depends on how much power you want to make and how much to spend ? Once you have the 190cfm or 200cfm heads installed and decent headers and cat back, etc. Then consider changing out the cam. Oh yeah if you have ever done it once (change cam) in these cars you will never want to do it again. It is a royal freaking pain and to my mind I will swap out the 305 to a 350 before I'll ever change the cam in a 3rd gen again.

my .02cents worth,
RP.

 

Thanks guys!!!! With all your replies I'm learning alot more about cams and how they work.

TriggerGTA - I can wait on headders, no problem. What brand headders are you talking about? Hooker, Heddman....and does it have the A.I.R tubes? You think the cam you have doesn't work because of your compression ratio and the other mods you have? I'm leaving my ratio the way it is and no heavy mods so maybe it'll work for me. I'm just taking a guess here.

I never new the cam I suggested was a "stock" replacement. I was quoted over $500 from Performance Improverments. Same price as 1992 350 cam from gm. I'm going to call gm and ask for the price on the 1996 LT4 cam. If it's in the price range of some the aftermarket brands then I won't go with the gm cam. Now wait..I checked the link and saw the numbers with 1.6 rockers....doesn't the crane offer better numbers with 1.5 rockers? I'm still learning this so bear with me.

But Trigger has the crane cam and say's it sucks. I want to feel the difference with this mod. I guess I'll have to take a chance with this over the winter and write about my experiance here.

Palric - Just as you said....I'm doing the cam job for the 350 short block I'm picking up. After you explained the work involved, I might as well do the swap. So the cam is not for a 305 rather a 350. I'm going to hold out on headders, Slade1 says it'll make my life alot easier to install them with the motort out. Other than that, my other mods will include porting out the intake, runners and phlenum. I already have a cat back 3" exhaust and after aftermarket muffler. So I'll be choosing a cam based on this setup.

I want a cam that I can enjoy from 1500 - 5500 rpm, if it exists. I enjoy off the line and mid range power/performance. No need for high end. This won't be an everyday car and I'll only be cruising with it or racing on the track not street.

 

So the cam is for a 350ci TPI roller engine? I'd go with either.......

1) LPE "216" cam if heads are stock

2) LPE "211" cam if heads are ported or aftermarket

3) Comp Extreme Energy 212/218 .487/.495 ground on a 112LSA

These will all work well with stock gears and converters. They will, however, work better with a looser converter.

 

88redxtsy i just picked up my flowmaster cat back today. right now i am thinking about the hooker headers 2055. but i am still not sure. and as for the cam, its not a stock replacement but very close to it. it does not suck. i was just after more power than it seem to be able to make. I DID SEE A POWER INCREACE just not as much as i would have liked. so i am going to change my exhaust to help it out untill i can think about swapping out the cam. the new cam will be done at the same time as a new set of heads.

there is no way that my compression ratio is hurting the power the cam is making

 

TriggerGTA - I guess I just misread your previous reply. Sorry if I offended you in any way and your engine design.

With a cam, myself, I expect to see big gains right away.

Inregards to your compression ratio, I mentioned that as a possibility because I was setting up for my next question...when I drop in a 350 short block in place of the 305, I was thinking of using the 305 heads on the 350. Now this is supposed to increase the engines compression ratio(very little) and are better flowing. That's why I asked about compression affecting the cam. I wanted to make sure that if I did this mod I would have to take it into account when I purchase a cam.

I got priced at crappy tire on hooker headders the other day actually. With air tubes it came to $836 before tax. I'd rather pay $900 like 92zedder and get the SLP's. I don't know if it was the 2055 model but I asked for heddman and they came back with a hooker

Keep in touch with those hedders. Lets see at dyno if 92zedder gets any gains from his new set. I say he'll see a 5hp increase

 

Hey man he/we better be picking up more than 5hp for $900 bucks worth of parts !!!

RP.

 

the hooker 2055 are the ones that i think i will get. i found them here in kitchener for $720+ tax

palric it might only be 5hp peak but what does it do to the HP curve? (hooker claim +20 at the wheel) we will see at dyno day if i have them installed by then.

 

$720???????????


sweet jesus.....you could almost buy a new engine for that.......that includes the y-pipe right or are the 2055s the hooker ones that they dont make a y-pipe for?

 

Guys, if you want Hooker part # 2055 try here..........

http://www.hi-performance.com

They are $579 and shipping is free. They are on pages 126-131 of the catalogue. You only have to pay one of taxes as well. I've ordered from them may times and have found their customer service to be excellent.

 

My car will likely be sporting a set of these for the 21st. They seem to be one of the few headers that will clear angle plug heads.

 

yes it comes with the Y

thanks paul i will check it out

 

thanks paul

i will be ordering the headers on Monday. thats the best price i have seen for them. i could not even order then from hooker,summit of jegs for a better price.

thanks

 

579 with the y-pipe is not that bad at all...those are a very nice header...if i could afford new headers i would go with the hookers, but i might opt for the long tubes to go with my dual exhuast, however i do like the fit of the shorty headers.

 

hay Paul i was just checking out the cams that you think would work. the 216 said in Johns good old book that "it would not need vale guide machining to the heads" what does that meen and would the 211 then need it? and why?

also the Comp Extreme Energy seem to have almost the same spec as the 2030 if you were to use 1.6 rockers. do you think there would be any difference if you only used 1.5 on the Comp Extreme Energy

 

In order to run bigger springs, which the "211" cam would require, you need to increase the diameter of the spring pocket in the head. They just mill a bigger and deeper "circle" where the springs sit in the head. Since the "216" cam will work with the stock springs you don't need to machine the heads. Any aftermarket head will come with a larger spring pocket. I think Comp Cams just released a set of small diameter springs that you may be able to stuff into the stock valve pocket if you want to run the "211" cam. They are shaped like a beehive, pretty cool.

The Comp EE line has very aggresive ramps which open and close the valves very quickly. They are a modern cam grind using modern valve movement ideas. TPI engines dig that. When you use a steep ramp on a cam you can run low duration and still achieve good lift. That's what the Accel/LPE and Comp EE cams do.

I'm not sure if the power gains would be dramatic. I would expect you'd gain some power but it may not be worth the time and $ involved in doing the swap. Personally, i'd do it if I had the $. I have the Accel/LPE "219" cam and I love it.

You may also want to check out the Comp 218/224 cam. You'd need a loose converter but it's a great cam.

 

F-CK i just called for the hooker 2055. it seem they have gone up in price!! now they are $679

 

Still cheaper than the $720 in town eh!$579 would be a steal,must be MONDAY.Next time your in the office at work say hi to Cindy for me

 

why dont you come by and say hi your self. when i think i might be able to find a road we could race on. somthing say...7500ft long

 

That would be great,who needs Cayuga or Grand Bend then.Can you taxi me on?Just found out over one of our famn damily get togethers that you work there.Guess it's one of those ironic small worlds again.

 

The price went up by $100? Well, i'm done with that place

 

I called them just for kicks and the told me that they are now indeed $680. Screw them, i'll get a set of SLP's and make them work for that price. How the hell can they justify a $110 increase? What crap. Canadian high performance parts dealers can eat a dick

 

they still have the best price for them. they told me it was holly that raised the price and that they just had to do the same. this new price brings them in line with most of the other people .

 

Oddly enough camaro part prices have seen to go up lately.. even my brakes have seen a hike in price of a good 15%...

I've noticed parts I've been eying for my car have done little spurts here and there in prices.
