rollers and valve coming from v8tuner along with some hd push rods, but I don't know what to do on springs......?
this?
Heavy duty double valve springs for use with Crane or CC Spring Retainers.

These are suitable for most applications but not for over 6500 rpm. For Race springs please contact.

For fitting of inner springs - the valve guide boss may require machining inorder to allow the inner spring to sit at the same level as the outer spring.

Spring installed height is 1.54"
Pressure 75 Lbs @ 1.54"
Pressure @ 1.04" 200 lbs

 

When upgrading cams, always get dual springs. It's a must if you don't want a valve kissing a head due to floating. Well worth the money.

 

Someone used SBC springs with no machining needed to spring seat. Close to 100lbs at installed height I think.
Can't remember who but it was here and not too long ago.
Not sure if that's what you are looking for or if they will work for you.

also wanted to mention, Turner engineering has King lead copper rod bearings if you are planning to get the crank turned or polished (which I'm sure you are). If not LC bearings probably wouldn't be a good choice. They only last on a new or perfectly machined/polished crank.

What I understand from the research I've done, most of the silicon aluminum bearings you see around are made in India and not consistent. Some are way off from what I hear. King bearings made in Israel are much better quality.

Aluminum are better for someone just slapping bearings in with no prep work. The silicon in the bearings polish the crank and do some of the work for someone just wanting to cut corners. I wouldn't use them in an engine like you are building.

If the crank is right then lead copper is the way to go. If Turner uses them in their engines, I figure they are worth ordering from over there and they are not very expensive, like $30 or $35 US I think plus shipping.
You may be able to find the King rod bearings stateside but will probably be higher than from Turner even after shipping. I remember seeing some awhile back for around $100.

The main thing I've always heard is stay away from any engine bearings made in India. Genuine King will have Israel stamped in the back.

BTW, Turner doesn't advertise them as King but I talked to them and they said that their rod bearings are King and what they use.

Don't mess about Dusty just lock onto one of these ............... more power than most anyone can handle.

Also good to eliminate valve bounce at top end revs and better gas seal if springs are good and progressive. Problem though, wipes out the seats and valve seat rims quicker ........... hmmm ............... nothing for nothing in this world though

 

dont know about this on rover engines but never hear of it affecting an LSx

 

why would you build a topend to rev to 6500, when you rev limiter is going to shut it down a 5400.

 

Yep, looks right to me.

 

Valve bounce is common with high lift, long dwell, sharp ramp cams but I've never tuned a Rover engine so don't know any specifics. With the Rover in a truck I'd be tuning for max torque and not so much BHP although every tuner says BHP is god.

 

You can readjust any rev limiter to what you want if it's programmable and the bottom end with take the strain. If not, change the rev limiter to a programmable chip.

Have to admit rods through blocks make a terrible expensive mess and don't even go there if the crank crumbles ................... lunchtime in hell
