LT4 HOT cam (was "Weakest Link" thread)
I wanted to start a new topic since many will probably reply to this.
Summary: I'm putting a '95 LT1/4L60E into a '76 and asked what would be the first changes you would make to give the engine a little more "umph" and what parts would probably need replacing first (it has 43K on it now)
Many replied w/ changing the cam and chose the LT4 HOT cam as a good selection. Somewhere I *THOUGHT* I read that this was great for the 6-speeds, but only so-so for the Automatics...any validity to this? If so, would a higher stall speed help? If anyone can shed some light, I'd appreciate it :yesnod: Also, many suggested tossing the springs that come w/ the HOT cam kit...which ones would be best?
* and THANKS again for all those who responded to my "Weakest Link" thread...excellent advice!

Re: LT4 HOT cam (DR'76)
I have the hot cam in my 94 auto ... no problems here! :D If you can do your own programming, this cam will work great on either. With a stock program, however, good luck sitting at a stop light! :jester

I think with the hot cam you need a higher stall converter, and at least a 3:73 rear since the cam makes most of its power in the higher RPM. My GS pulls like a mother from 3000 up!!!

A higher stall speed will help you off the launch but not in that 1-2 shift.
As for the Springs, I'm using those springs with my zz-9 cam and they seems to be doing just fine, however, I'm also having problems with the stock ECM not being able to handle a .52 lift. I've got an Ed Wright special on the way to fix that.

Re: LT4 HOT cam (mn_vette)
The hotcam really pulls above 4000, which is great for a manual because a redline shift will leave them at 4000rpm in the next gear. The auto's however get stuck at 3000 which means they are SOL.
