Warning: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in ..../includes/class_bbcode.php on line 2962 Not happy with XE256 in 401.
I've been running a comp XE256 in my 401 for a few months now. I've not been really happy with the performance. It's got great low end grunt, but it falls off a little too quickly.
I've been searching for an ideal camshaft for my engine. It's a 40 over 401 with Keith Black pistons. Around 9.6:1 compression. It's in my auto tranny 77cj7 with 31" tires and soon to be 3.73 gears.
I'm looking at the comp 268H. It has a little more duration that the 256. 218,218 vs 212,218 @.050.
Anyone running this cam?
Also I'm not sure on the valve springs. Currently I'm running the comp 926 springs with a rate of 415. The 268 cam specs the 940 springs with a rate of 241. Should I change out my springs, I happen to have a very low mileage set of the 940 springs from a previous project.
