I am gonna get my motor freshend up soon and was wondering what peoples bearing of choice is for 7500rpm?
also what are you guys having luck with as far as timing chain and that kind of rpm?

thanks, mitch

 

FWIW, I use a double roller chain and I run clevite coated bearings throughout the engine

 

I am leaning towards calico coated clevite main and rods with coated durabond cam bearings
I am studding the bottom end and getting a oil cooler and oil temp gauge to keep an eye on Temps

 

I'm running a Katech C5R single roller chain and cloyes hex adjust - I think it's pretty good, thoughts?

Oh and get the correct bearings for your Crank - stock style "P" for stock crank and chamfered "H"narrow style for aftermarket crank. Coated is a personal preference and depends if you have clearance for the coating.

 

I have been thinking of trying the c5r chain out. I currently run a ls2 with a trick flow dampner.
I will be getting the correct style for my crank and the coated bearings should put me pretty much what I want to be at as far as clearance goes.
my truck can sit for a week or even more at times depending on weather and I will be running 5-30 oil so I like the coating for those start ups if it sits for abit.
it also gives me that extra second of safety incase I do lose pressure.
thanks for the comments so far guys, hopefully more people will chime in on what they use.

 

I use King HP Series bearings in all of my race engines. Some of them cross the finish line at 9,000 RPM or more.

 

I personally like the king hp bearings but the ones that tsp sent are for sbc, and they are a bit narrower them the stock ones. I haven't had issues, just odd. I swear my oil pressure is a bit less with the king bearings.


Don't stud the bottom end unless you're going to get it align bored. The studs distort things a bit from more clamping power.

 

Calico coated Clevite bearings is a good way to go. I've been involved with plenty of builds that see a good bit of RPM while using the standard offerings from both Clevite and King with good results. I think a lot of it comes down to builder preference.

 

I currently run king main and rod bearings and durabond coated cam bearings.
it will most defanitly be getting align bored for the studs.
thanks for the input Aaron, I think I have made up my mind and I am gonna go with the coated clevite bearings
