I'm new to picking out camshafts so I wanted a second opinion on one that I've found. I'm working on a 1988 305 tpi. I have headers and full exaust. I will be adding a set of full roller rockers, 1.5 ratio. Otherwise stock. Here is the cam I like so far:

Xtreme Energy XR269HR-12 Hydraulic Roller Camshaft
Operating Range: 1600-5400 RPM
Duration Advertised: 270° Intake / 276° Exhaust
Duration @ .050'' Lift: 218° Intake / 224° Exhaust
Valve Lift w/1.5 Rockers: .495'' Intake / .502'' Exhaust
Lobe Separation Angle: 112°

What do you think??

its a healthy cam for a 305. with a properly tuned chip, open the plenum, snd s better set of runners, and you should be golden.

I have that cam in my 383. It's fairly close to the specs of the LT4 Hotcam.

In my 383 it's got a really decent lopey idle. Listen to some of the sound clips of people who have that cam.

I'm not quite sure how it'd act in a 305.

That is a big cam for a 305. I am having some trouble tuning my ZZ4 cam in my 88 tpi. I would guess you would be tuning this yourself? If so I hope you know what you are doing.
