Wondering if anyone has used this spring and if it is a true drop in with stock retainers.
This is the MP cam I have and it recommends stock 340 replacement spring that I am using but I plan on replacing. I know the comp 901 spring is a drop in and will work, just looking for a little more spring for a little more rpm. I am running 273 adjustable rockers also.
Advertised Duration 288/288
@0.050" 245/245-
centerline 108
Lift 497/.497
recommended springs P4120249
In my search I came across them as replacement with these specs for the 926 comp spring
130lbs at 1.70 installed height
317lbs at 1.15 valve open
The stock replacement MP springs I have are
90lbs at 1.68 installed height
230lbs at 1.27 valve open
The comp 901 specs
101lbs at 1.65 installed height
242lbs at 1.25 valve open
