Thread: question about retainers

VSS-105 Specifications:

• Installed load is 105 pounds at 1.800", 127 pounds at 1.720", and 293 pounds at 1.200".
• Coil bind height is 1.125".
• Outside diameter is 1.290"/1.060" and inside diameter is .885"/.656".
• Maximum lift supported @ 1.72 (stock retainer install height) - .595"
• Maximum lift supported @ 1.80 (Manley retainer install height) - .675”

I'm assuming you have the blower cam?

This is on Intense web site:

The Stage 1X Cam is the IDEAL aftermarket cam for use with stock heads, lifters, rocker arms, retainers, and pushrods. Aftermarket lifters, pushrods, and retainers are not necessary at this level, but there are certain reliability and performance gains to be had by replacing these items during your cam change. We always recommend and/or install 105# valvesprings with this camshaft. The powerband is strong from 2,600 to 6,600 RPM. With the supportive induction and exhaust mods in place, you should be able to run a 3.0" supercharger pulley with no intercooler when using this cam . Or, you could run a 3.25" supercharger pulley and increase your timing advance. The Stage 1X cam is designed to max out the stock cylinder heads, both in terms of air flow and also with regard to valvespring retainer to valve seal/guide clearance. Customers should check all necessary clearances especially if upgrading to aftermarket valve seals. The Stage 1X cam also works very well with a small shot of nitrous oxide (25-100 horsepower shots)

Hope this helps.
