Andrew, Jeremy dropped the LT4 hot-cam for his next build up. He's going with a 383, and he went with less duration. He's sticking with the ported plenum/SLP runners/ported vortecs, but his cam is actually closer to what I'm running. I think its a tad larger, but not by much.

Yeah, the LT4 setup moved really good, but it wasn't really the best cam even for a modified TPI setup.

Stock cam? Thirdgen.org had a bunch of cams listed but the server quit. I'd stay within 210-215* duration @ .050" on the intake and a LSA of 112-114. I'd also stay with a split duration cam with stock heads, the exhaust port doesn't flow all that well. My setup is pretty mild. Ported everything I can. 211/219 LPE cam. AS&M SS runners, port matched base, headers full exhaust.

92purplehaze, comp cams has a 210/220 cam that would probably work decently well with your setup after a tune. It would start right up and idle without problem. So driving it without a tune wouldn't be a major issue, though I'd watch out for gas prices as your mileage won't be the best without a tune.

 

Hey.. fruityone & lt4fd.. THANK YOU!!!!!!!!!.. those are the kinda answers im wanting.. now i have a good idea of what kinda cam the l98 will LIKE.. not what i like.. what the engine will like.. THANK YOU... I am most definatly going to start doing homework now on prices and availability on the type of cams you suggested..

 

Hotcam will be the least expensive for sure, cc502 is about the same size with a tad less exhaust duration but will require a little bit stronger valvetrain and yield slightly better numbers across the board. Those are probably the biggest you should go, and lingenfelter sells the size cams that fruityone was suggesting, which a little smaller, as well as tpis I belive.

 

Most of the time you can find the Lingenfelter cams on ebay, actually being sold as overstock through Lingenfelter themselves for about $250. They are really easy to work with. Though don't let them talk to you about their head porting packages, or their valvetrain setups. Both will cost you more than an arm and a leg.

They wanted me to send my heads in for the best gain. Well, at $2,200 thats ALOT of money for CnC porting on stock heads!! I'd rather buy AFR's or a similar aftermarket brand and have light work done on them. Much better results that way. The valvetrain components while top notch, were also top notch prices, about $600 in springs, locks, the like? I don't think so!

The LT4 valve train suits me just fine. Works great with this cam.

 

looked at comp cams site.. just wondering if this is the 502 cam you suggested?? "GM LT1 & LT4 350 Xtreme Energy 269HR-12 Cam".. says its works well with a LT1 with upgraded computer and exhaust.. I also made the call and talked to one of the guys there.. his suggestion was this.. part number 08-501-8 212 218 duration 488 495 lift 112degree.. any input on his idea?? from the search I did this cam they suggested is bigger than a hot cam, thats of course if the numbers I found for the hotcam are right.. is this too much cam?? everyone has a different opinion and I guess im just going to have to go with something that someone has in their car that they KNOW works good.. anymore help fellas?

 

i don't think that is too much cam at all,with the duration @.050 it will have a small but noticable rumble at idle it should pull nicely,what are your intensions for the car?
hot cam w/1.6 rockers 218/228 .525/.525 112*
slp cam w/1.5 rockers 226/228 .495/510 112*
lpe cam w/1.5 rockers 219 .560 112*
these examples of cams have a moderate idle(small rumble)run hard and don't require a bunch of other mods to run good,custom chips are advised though for best running quality,all of these cams have proved to run in the 12s with no more than 3.42 gears,2600 stall,headers etc.

 

Intentions for the car kinda go like this but then again since there are no parts in my hand yet they could change at any moment.. First throw the stock L98 in it with a cam.. Then be very happy since its going to stomp a mud hole in the LO-3 thats in it now .. After its in and as money allows I will go with a set of iron heads from a local engine rebuilder that will be a little massaged, like a little porting and possible polish.. Probably end up putting a modified LT1 intake on it as well.. I still need to do a search and find out what all is involved in that other than the distributor hole. The car will have headers when the engine goes in, headman shorties due to my 2" lowering springs, and a nice 3" exhuast, no cat, no smog.. 3:23 or 3:42 lsd.. some SFC, PR, and either nitto or BFG drag radials... I dont want the fastest car in my town.. just want to keep up with all the other fast ones like the LT1's and possibly even the LS1's.. but I am not even going to try and guess how fast the car will be because everyone gets different results from their mods

 

WELL you seem to know what you want,the man you need next will be john millican you will find him here www.lt1intake.com check out www.stealthram.com as well......

 

thank you for the link.. that makes my search for that alot easier.. I think since eventually I will put a nicer set of heads on the car as well as a better intake, I will go ahead and just get the hotcam and if its just a little too much cam for the engine now ill just live with it until the other mods are on.. now the last thing to do is cover the tuning.. because lord knows it will need it..

 

I already have a converted LT1 intake sitting on the side. Almost ready to go on the car.

 

well guys I guess that ends this thread.. I cant thank you enough for all the help.. I will just go with the L98, LT4 cam kit, headers, and custom chip of course... then I will step up the heads a bit.. and then I will convert to either LT1 or if I can find a good deal on a HSR I may go that route.. Either way I am sure it will be a pretty good running car.. at least a WHOLE lot faster than what I have now... hey, who knows, I might even throw a 75 shot of happy gas in there just for those races that are really close and I wanna win..

 

I have a zz4 cam i can sell you for 50 bux plus shipping

306 is WAY too big for a stock l98

This cam has the follow

208/221 duration at .050
.474/.510 lift with 1.5s
.505/.544 lift with 1.6s

112 LSA

lot better for your set up lemme know.
