Where do you get the Ferrea? How much? Do they have them for the lt4? Can you use 918's in lt4's? The guy I bought my car from said he has heard a lot of problems with the 918's breaking. Anything to that? 918's are from Comp Cams right?

 

I've seen quite a few failures and "fatigue" on the 918's. Even Comp don't really spec then till .600 anymore.

 

What about COMP 977's All the way

 

I only got about 10k miles out of my Crane duals before I had a failure(s)

I am now trying out the Patriots

 

We prefer the Patriot doubles over just about everything else out there. They are rated to .650 lift, but we've run them past that with no issues We stock them, so shoot me a im if you need a set If you order online they should ship same day

can you use these patriot double with comp hydrolic roller lifters. I really don't want to go solid if I don't have to.

Yes you can use them with the comp hydraulic rollers.

 

which sponsor has the dual patriot gold vlave springs? I've been in patriot performance, pace, and a couple other one and have not found them. Approx how much with ti retainers for lt4 396 for up to .600 lift?
Thanks,
Andy

 

Call Terry Wilkes( look above your post ) Or Texas Speed and Performance.

Patriot Dual GOld Springs. I got them pressure tested. They are just as good as the rest. but cheaper

 

Comp 921s here. I got them for a great price from LG Motorsports. Nice fat dual springs.

 

The whole 918 breakage thing is a bunch of crap..it's all he said she said crap. There were very few failures when they first came out..since then..no failures. Also the whole "gotta change them every 15K" is crap too
