Lol...

 

That is good numbers for non spray top end mph's

 

Yea it sucks, what do stock LS1's run down there?

 

Turned 101 stock brand new after I learned to drive it.LOL first couple passes were like high 99s and 16 seconds. Got it down to a 13.9 at 101. I forget the 60ft times this almost 10 yrs ago.

 

Stock? Depending on track conditions, driving, etc.. you see them from high 14's all the way to low 13s.

 

Junk cam

 

How is that a junk cam?

 

you should explain more about why....

 

Gotta love wisdom like that..

 

It makes my life so much easier to learn with info like that GM did use this cam kit in the LT4'S so it can't be to junky...lol

 

It's a perfect cam for someone looking for a bit more performance in their daily that don't want to go over-kill. Gas economy with it is great, and sounds pretty damn nice with the right timing settings. It's also good enough to get folks into the 11's with full suspension and slightly ported heads (my friend's M6 with ported heads, hotcam, 1.6rr's, 3.42 gears, and bolt ons went 11.8 with STOCK suspension) come on now, unless youre looking into building a crazy track car, the hotcam is enough to meet most people's needs.

 

Can anyone tell me if you need to change the rocker studs to 7/16 like the true LT-4 when you install the kit.
Thanks,
Steve

 

I think the cam used in the LT4 was actually smaller than the LT4 Hotcam that they sell in the kit. Either way it's not a junk cam by any means for what it is.

 

the hott cam was NOT installed from the factory or slp....the cam for the lt4 was almost the same as the lt1 cam except for the lobe sep. lt4 330hp cam was 115 lobe sep...and cthe lt4s came with 1.6 rockers..

the upgrade to 7/16 studs is to help stop stud flex in return can get a lil more HP andTQ from this mod especially on the upper RPM level.

 

Another angle to look at this fron is how many of the parts can you reuse as you mod further? The rockers are 3/8" stud and limited to like .550 lift. meaning soon as you decide you want to do heads and cam you will be buying another set of rockers.

You may say at the moment you don't want to go that far but one day you will and it is cheaper to buy things once. Most of us eventually learn that doing things cheaply is rarely least expensive in the longrun.

I am of the opinion the LT4 springs are insufficient, if not today, they will be a year down the road once they are broken in and begin to wear. The rockers are not up to the task of the average cam sold with a heads and cam package. So even if you decide to use that cam I would urge you to no do the whole kit. Right off the bat buy 7/16" studs and non-sa rockers with a set of guideplates and you will never have to buy those parts again.

 

You do not need non-sa rockers for a hotcam.. But i see what you're saying. for the longrun if he decides t ogo with a bigger cam

 

unless you want to man up with a set of jesel shaft mounts!

 

LOL, yeah, because those are a good way to spend your money on a mild street car.

 

think for the future!
since we seem to never be done with upgrading!
good rockers are 300.00
arp studs 30.00
the best are 875.00

 

Dang guys, complaining about ONLY getting 70hp from a stupid cam. On Modular Ford engines, improved heads, cams, and intake, with supporting mods, barely gets you 70hp.

Thats why I'm into camaros now! Cheaper alternative!
