Makes me kinda weepy eyed....

Good luck with the install and your relationship with your tire distributor....

This one may actually be easier on the tires since the torque down low is a little less than what I currently have but the top end hp is significantly higher. :confused59:

Which rig is this going into?

Beautiful intake!

Really nice Tim. That should be entertaining!

I hope it will be, I'm going to experiment with the lsa of the cam in an attempt to bring the peak power down in the rpm range to increase the life of the engine.

[wiedemab]

Yikes -- that sounds like it's going to be wicked....

- - I have a Nova that you could store the old engine in! ;)

I think you'll have to fight Deb for the old engine.... there's already some negotiating (threats) going on about that. :D

[wiedemab]

Hell, I'd take her old engine.... beggars can't be choosers, right! :D

All kidding aside, you with a new/better motor and her with your old motor...... Look out - -- the McGiltons are stepping it up yet again!

[71RS/SS396]

Here's where we are now, may do another cam test.

hydraulic roller to 7800? :eek:

pretty bad ass there Tim

We've had LS hyd rollers up to 8,500! :confused59: Fwiw those numbers are with all the accessories on it and the water at 180*

I was thinking more of the longevity of it going that high.

Tim the motor is bad ass. My iPhone showed the dyno sheet upside down and my kids were looking at me funny while reading it all contortioned :D

Can you comment on valve float issues on a hyd roller turning 8500? How do you and Kurt get around it?

So far we haven't seen them be any worse than a solid for durability. I plan to maintain them as I would a solid, the lifters and springs will get replaced every season for insurance.

We are using a stud girdle that we make on the rockers , short travel lifters, and I also think how Kurt goes about setting up the valve springs helps as well, Kurt is a guru with these engines and knows so many tricks that are unconventional. The block also has a raised cam which translates to shorter pushrods and thus less deflection.

It reminds me of my engine, but way nicer. :lol:

I'm using a 4.185" bore and 4.125" stroke with RHS LS7 heads, Fast intake, wet sump and smaller cam, 244 259 @ .050. makes about 600/570 on a chassis dyno while being run up to 6800rpm. With the gearing and torque available it doesn't seem to make a difference when you shift as long as its above 6000rpm.

the way your engine builds power should be great for autocrossing. Always impressed with what comes out of the shop!

Matt, you need the Ozmo intake for your engine :D, that Fast intake is choking it, I saw a 50 hp increase with the Ozmo. The 102 mm tb is too small for the cubes you have.

Tim, I have Jenvey Cross Ram individual throttle body setup for an LS7 sitting on the shelf. I tapped all of the runners to be able to connect them to a distribution block for an idle air control valve and map sensor, but have yet to get the correct length injectors, or re do my ecu (mefi 4b) and upgrade to something not from developed around the time of the wheel.

If you want to "test" it, and compare to other options, I'd be happy to send it over. It's just collecting dust right now.

I appreciate the offer Matt but I've tried those ITB intakes before, they make big peak power but the low speed drivability is tricky unless you build a plenum and use a single throttle blade on each plenum, they're pretty much like a 2-stroke.
