I have a stock 1991 350 TPI and I was wondering if I put a stock LT-4 cam in it would anything need to be upgraded. (Computer, fuel pressure, injectors) I also wanted to put 1.6 Roller rockers with it, would this be too much lift. Would 1.5's be better? Thanks for the help

 

the stock LT4 cam is barely larger than the stock LT1 cam, I dont remember the specs but its not much more lift. With 1.6 rockers it may be getting close to the max lift of your stock valve springs. I'm not sure what they can handle. I've been very impressed with my Hotcam and 1.6 rockers, its quite a bit larger than the LT4 cam. might want to check into it.

 

It seems as though everyone is using the LT4 hotcam....it makes me think that either everyone has gotten the same advice, or it really is as good as everyone says....what is the deal...is there anyone out there who has used somethin else?
