Hello. I own a 1991 RS, that will be undergoing an LT1/T-56 swap next month, so right now I am doing all of my research and part gathering. I have done a lot of searching here and other message boards to avoid asking stupid questions that have been addressed many times before. Well here it is:

I have noticed the CompCams 305 is popular here and decided I will be using it. At CompCams website they have two different valve spring recomendations depending on which particular page you are one. They are a single spring (983-16) and a double spring (986-16). Which would the best for use with this cam? I never plan on going with forced induction, not ever producing gobs of power.

And in case you care what my car looks like (Along side a friend's T/A)

i would personaly go with the 987s people have had good luck with these springs. and if you ever decide to go bigger you can without having to buy new springs.

 

The single spring would be enough for what you're doing. Unless you're going to race a lot. If not, the single is strong enough.

 

I second the vote for the 987 springs. Haven't heard a single complaint, and it may save you from paying a new set if you do a cam upgrade.

The price difference can't be THAT bad either...they're only $89; worth the few extra $$$ to get the better of the bunch.
