SPACK 71 Posted December 14, 2019 Is there a company that sells a stronger better PUSHROD for the XF EFI ENGINES.., I rarely ever go pass the 5000 rpm,s, YES the SVO does do it, but I keep bending the RODS, when I do, so its a rarity..also WOULD it help to change the LIFTERS?..CHEERS.

gerg 10,872 Posted December 14, 2019 Precision sells 3/8” diameter Trend pushrods in whatever length you want, but they're not cheap at 18 bucks each.You often have to go with fatter pushrods when they're as long as those on a crossy.Are you running stock valvesprings? If so, you might be getting valve bounce, which will bend pushrods in no time.Sent from my CPH1903 using Tapatalk 1 SPACK reacted to this Share this post Link to post Share on other sites
SPACK 71 Posted December 15, 2019 Double valve springs on it,..and you said PRECISION, is that there full name..? Share this post Link to post Share on other sites
gerg 10,872 Posted December 15, 2019 Double valve springs on it,..and you said PRECISION, is that there full name..?Precision International, and their website is quite comprehensive. They deliver promptly too.Maybe it's just that long pushrods don't like rpm, whether you're using stock springs or stiffer.Sent from my CPH1903 using Tapatalk 1 SPACK reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted December 15, 2019 Crow sell 5/16, .110" wall thickness pushrods and most sell 5/16.080" wall. 3/8 pushrods are also available as gerg has highlighted. The stock pushrods are marginal at best. 5/16, .080" wall would be the minimum I'd use. 1 gerg reacted to this Share this post Link to post Share on other sites
SPArKy_Dave 9,066 Posted December 15, 2019 I thought stock push rods were the safety net, against over-revving a crossflow? 1 ando76 reacted to this Share this post Link to post Share on other sites
