Used LT4 Cam Question.....
Got a question for all you LT1/4 guru's....
I have a chance to purchase a used 30K miles LT4 cam for $75. I have a 93 LT1. I was thinking about just adding 1.6 or 1.65 rollers to my LT1. Would I see more of an increase to go thru all the work swapping out the cam and adding rockers or just add the rockers?
Or should I just hold off and get a LT4 Hot cam??
Opinions greatly appreciated.
Thanks

Absolutely do not get the stock LT4 cam. The difference between it and the 93 LT1 cam are mere thousandths of an inch. For all that work you would see honestly see no difference at all. An LT4 Hot cam is only about $200. You would get much more for your money and work with the Hot cam.

Thats my thinking, just wasn't sure... To get that extra 30hp from a LT1 to an LT4 was intake, heads, roller rockers and a cam... So I guess the LT4 cam just would not give that much. Is buying used ok??

The LT4 cam has slightly less lift (with a given rocker arm) and slightly more duration. Definitely not worth the bother.
