I think the stock LT4 cam would be a good all around cam, but like 357 says the HOT cam will give you more on top. If you are going to do a stall anyway, that may be what you want. The 383/ramjet cam has less duration and lift than the stock LT4 but should boost the low end from what I read about it. It would probably not give you the top end you want.

 

do you know what they consider the rpm range on this cam? i cant really rev past 5500 with the intake setup on the 1st gen vortecs.

 

I think GM lists it to 4500 but you know it will pull past 5000...

 

ok, well i think im gonna go with the hot cam. its the one i have been eying for a while. if i don't like it i guess i get to pull the whole front of the engine apart to change it again, which means i will probably do more work elsewhere in the engine

 

I think you will like the hot cam. Just get a stall and a custom tune, a hand held programmers not going to cut it, and you should be ok. I did a search on the hot cam and found a dyno graph comparing it to the zz4 cam and the hot cam out performed it by quite a bit, especially in the upper rpms. There is a guy who posts on fullsizechevy who built a 383 using stock ported heads and the factory fuel injection with the hot cam and made around 330 hp at the wheels. Thats not much compared to some of the trucks on this site, but considering the crappy fuel injection the first generation vortec trucks came with it's pretty impressive to me. I got my cam from Scoggin Dickey for $175, I believe they are a little over $200 from Summit. Good luck with your project.

 

i know which guy your talkin about on there. he said he lost .3 seconds on his 1/4 with the hot cam when it was a 350, i don't know why but i hope that doesn't happen to me. he says its to aggressive for a stock 350, but i don't know. thats the one and only reason i question this cam is because of that statement by him

 

Well it's definitely not too much cam for a 350, but it is a lot for the injection system on our trucks. The LT1 guys use that cam all the time in their stock motors, but they have a much better injection system. I could easily believe he lost that time with a stock automatic transmission, but if you had a 2800-3k stall I dont think that would be possible. The only modification you have to make to the cam is the dowel pin has to be shortened to run in your motor.

A stock LT1 or 4 cam may be better all around, but it definitely will not pull as hard above 2500 rpm and will produce no sound over your stock cam what so ever. In case you didn't know, the stock cam specs on your vortec are .414/.428 lift and I believe the duration @.050 is 192/197. Send that guy on the other site a pm and see if you can get some more specifics from him. I believe he goes by vortec stroker.

 

ya that is his name, andmy town is fairly close to his town. i personally belive a lot of his problems was in tuning and setup, but he said it was because of the intake manifold. I will have to get more specifics from him and find out. thanks for all the help, and i didn't relize that is what the stock vortec cam was. Do you know if the stock vortec cam has a 114 lsa?

 

No experience with these motors, but I also found these cams...
