Its about time for a valve spring swap on the ol' TA and am debating which route to go...I currently have a TSP 224R cam with a set of 918's. Should I go back in with a set of 918's or upgrade to a set of dual springs? I found a nice deal locally on a set of REV 1116 dual springs/tit. retainers but I had heard before that dual springs on a small cam like mine would actually rob power...is this true? Also what are your opinions on the REV dual springs mentioned? Thanks in advance for your help!

 

If I was going to upgrade from the 918s I would go with the PRC kit. I have had them in my hands and the fitment of the components are nicer than anything else compairable.

 

The single vs dual spring deal is really up to you though I am not a fan of beehive springs in general so I'd go with the duals.

As far as the REVs are concerned, I've had a set on my car for almost two years now and, yeah, they're getting tired and I'm replacing them this week in fact, but they've done a great job in my car.

FWIW, I'm putting a set of PRCs in this time.

This thread is like deja vu.

 

LOL...thanks for the quick and accurate replies...

 

A 918 spring would be perfect for that cam. You will probably drop a little RPM by going with a dual over the light weight of the 918. Plus the harmonics are far superior to a dual.

 

A recent Hot Rod magazine article stated, 918's made more power than conventional springs in big block chevy engine.

 

Go with the orginal Patriot "Gold" .650" dual spring. Only $279.50 for the entire spring kit !!

 

I'm running the Patriot Golds with the 224R cam. Works fine.

 

you could easily get a set of 918's for under $200...plus a stock/steel retainer weighs less than dual ti retainer

 

My Manley single spring titanium retainers weigh less than the smaller OEM steel retainers. I compaired them both on my RCBS electronic powder scales.

Comp 918's with matching Comp titanium retainers is the best way to go.IMO

 

thanks guys...I think my brother is just going to sell the REV's I was gonna buy from him...I dont feel like messing with the install at the current time!
