I know the LT4 Hotcam kit is the best bang for the buck when it comes to cam packages, and I know the springs are "marginal". What is the maximum RPM that you guys would turn with the LT4 Hotcam and the LT4 springs?
Thanks
Matt

 

The LT4 motor redlined at 6300 with those springs, but with a smaller cam with less lift. Since the hotcam peaks at about 6000 anyway, I wouldn't turn much more than 6200.

 

I would agree with the post above, around 6200-6300 rpm.

 

K thanks guys.
