Title: More tech.FK45 and Scat pushrods Post by: airstuff on June 12, 2008, 08:42:57 am Can anyone tell me If Scat 3/8 4340 Mantons with .035'' wall strong enough to withstand the fast closing ramps of the FK45?

I've never personally used the Scat's, but I wouldn't be at all concerned. I ran Scats once. The ball tips wore away in about 6 days. Valve adjust kept going away (Noisy) and I pulled rockers to inspect skuffer pads and lashcaps. I found the ball tips on pushords were worn sharp. I was very displeased. I have Berg black chromos in my car now, almost 10K miles on them this month.

I would use the thicker .058 myself but I think the ones you have will be fine cheers richie,uk Title: Re: More tech.FK45 and Scat pushrods Post by: Jim Ratto on June 17, 2008, 00:40:09 am I used Berg's 80,000 psi 3/8 chromoly pushrods on my daily driver with an FK45 for over 50,000 miles with no problems.

Scat admitted that the ends missed the heat treat... ::) Title: Re: More tech.FK45 and Scat pushrods Post by: stealth67vw on June 17, 2008, 00:40:37 am I just ordered the Berg 80,000s to use on my FK-45. I've had great success with them in the past.
