Dale, just wondering what kind of a pain it was on the those valve covers. I have the Katech covers also and I will be running Comp Cams shaft rockers which I think are made by T&D. All my engine components just arrived to Wegner Motorsports this week. Casey Wegner warned me they were having trouble finding valve covers to clear shaft rockers on another build they were doing. I just got the valve covers so I have not shipped them to Wegner yet. Wondering what the work was to make them work so I can let Casey know.

Greg... I'll post up some pics tomorrow to show how I modified the covers...

Dale,

I've really enjoyed your thread except I've come down with serious engine envy now.

Is the HalGuard fire extinguisher mount part # BB250P? I wanted to make sure before I ordered one.

Thanks

Bryan

Thanks Guys Wow... what a fun day!


The car ran great... the new engine is awesome on the track . Accelerates hard... rev's way up and runs super smooth. This was a whole new experience for me with the new engine and T56 trans. I will be running on adrenaline all weekend after this!

I have been doing this for several years now and this is the first time I have gone out on a track day and had zero leaks... no engine oil leaks ... no trans oil leaks... coolant leaks... or power steering fluid leaks. The engine ran at 180 degrees with no heating issues... I think having the dry sump system and extra volume of oil may play a part in this.

I took some video out on the track today and will post up tomorrow.

Greg... I tried several different options to try and find valve covers that would clear the T&D shaft rockers. The Katech valve covers are the only ones that even came close to fitting. I started out with their cast aluminum covers... ran them for a while... then bought a set of carbon fiber valve covers. Both sets had to be modified to clear the rockers.

I tried stock LS covers with 1/2 inch spacers, Holley aluminum valve covers, and neither would clear the rockers without major modifications. The Katech covers required the least amount of grinding to fit. I am using GM LS7 heads and the T&D shaft rockers with 1.8 ratio. Not sure exactly what your running.


Here is a shot of the T&D rockers... they come right up next to the rails... Nutter had to modify the rockers and heads slightly just to get some clearance.




Here are some shots of how I modified the Carbon fiber covers for clearance










When I mounted the modified valve covers I pushed them up towards the fuel rails a much as possible... the rubber o-ring seal will end up right on the edge of the lip on the head. It is a very tight fit for sure.. but I was able to modify the covers and make it work.




Hope that answered your question... it's always a pain for the engine builder when they have to do extra work to make things fit. You just don't have a lot of options to clear the T&D 1.8 rockers.

Awesome post Dale, that really helps me out. Thanks for posting so much detail. It's people like you that make this such a great site.
