LT4 Hot Cam specs
I need the equivalent of a cam card for the LT4 hot cam. Chevy doesn't release some of these specs and the other sources I tried are missing half the data as well. Does anyone know where I can locate this stuff?
I'm programming my Accel Gen 7 DFI and I'm taking an educated guess on some of the cam variables. The Accel software generates several critical tables of data for the ECM from these numbers, including air/fuel ratios. The cam card will help a lot. It starts OK but starts to run rough and stall after a few minutes and won't restart. It seems to be dependent on temperature because everything is OK when it cools down again. The engine is a 383 stroker with a number of other mods. Thanks Ron |
All I can find is 218/228 at .050 .525/.525 and 112 LSA. But you probably already know this and need the other stuff on the card. Here is a bump for you.

A while back I called Scoggin Dickeys and asked them for some info on it. I was playing with my desktop dyno program and it asked for several things that I didn't know.
I don't remember the questions or answers, but I do remember that they answered all of my questions. Try giving them a call. |
I have that cam profile in Desktop dyno, which has the info you need. I don't know how accurate it is, but it has to be close. Unfortunately that's at home and I'm at work right now. I'll try to remember to get it for you tonight.

Try these values and see if it runs worth half a crap
Seat to Seat Duration: Intake 279 Exhaust 287 Intake Valve Opens 30.5* BTDC Intake Valve Closes 68.5* ABDC Exhaust Valve Opens 78.5* BBDC Exhaust Valve Closes 28.5* ATDC I have no idea if these values are correct or not. I know that it gives pretty accurate results vs. real world using Desktop Dyno. Good luck! |
