I am looking at the pro-gram engineering splayed main caps for my 1996 z28 LT1 and was going to get item# SB350C22 with the 22 degree outer bolts and the website is http://www.pro-gram.com/catalog.jsp
The reason I am specifically trying to get this item number is I may be able to get them for a good deal. Will these specific splayed main caps work for my car. Thanks for any help.

 

That is the correct part number bud. I am also using those caps (PT number SB350C22) in my new 383 stroker setup. I hear from lots of people that they are VERY good caps, machine shop doing my 383 also liked them. Get'em, have fun

 

Pro-gram is my choice for main caps, just make sure you use the flat caps so you can move the register point out to the pan rails.

 

Not sure what you mean by flat caps, but is the item number I gave in my first post the flat caps that you are recommending.

 

There are stepped and flat caps... unless you are going crazy on the power I would just stick with the stepped caps since they are easier to install.

I'm using a set of these on a motor right now, they make very good caps.
