from what i have read the lt4 springs are good for only lt4 heads with the lighter valves.if you put them on standard lt1 heads with the solid valves can get a chance of valve float.and the cam is barely better than a stock lt1 cam. just has a tad more duration and lift.the rockers bump the lift up a little also.i always hear of complaints about the performance of the kit. it really is only a mild upgrade and cant really expect a huge increase in power.if you really want to put down some nice power you might want to get a bigger cam and springs...but just my opinion

lol another dissapointed consumer, thats a very common response. Those numbers are with supporting mods such as headers and CAI

My car only made 230 to the wheels totally stock, so 330 would be a 100 hp gain for me, lol. I agree that bolt-ons and a hotcam will be right around there with the hotcam kit. With tires the car will run easy 12's (probably 12.6-12.7) full weight.

2. your thinking of the lt4 cam and he is asking about the lt4 hotcam. The stock cam being 201/207, .447/.459, 117 Lsa, upgrade to the hotcam which is 218/228, .525/.525 with 1.6 rr and 112lsa is more than just "tad more duration and lift."
3. "i always hear of complaints about the performance of the kit" Well the average hotcam user with see 330-340hp with this upgrade. Thats only 55-60hp over stock.
4. "if you really want to put down some nice power you might want to get a bigger cam and springs" With bigger springs and a bigger cam don't forget that you'll have cam surges, no low rpm power and revving your engine to 6600+

Yes you can put the LT4 springs on the LT1 heads, and most people who make such a poor decision are not going to be aware enough of what is going on to realize they lose performance to valve float with relatively few miles.
Point being, sometimes good reviews are the product of ignorance rather than a really good setup.

hotcam=disappointment IMO...i would go with at least a cc503. but since you already have the cam, i'd say just do allll the boltons on the car, stall(if auto),gear,ewp,LT's,tb,rockers,intake mani, etc etc etc...ive seen a few hotcams put down decent numbers, but most of the time they run high 12s or low 13s and put down around 330 at the wheels. this is all IMO, and based upon what ive seen btw.

1. you can use the lt4 springs on lt1 head with no problem, I did for over 2 years like many other people have.
2. your thinking of the lt4 cam and he is asking about the lt4 hotcam. The stock cam being 201/207, .447/.459, 117 Lsa, upgrade to the hotcam which is 218/228, .525/.525 with 1.6 rr and 112lsa is more than just "tad more duration and lift."
