Here are Pics of Jack Hardy's Lexan Insert Valve/Rocker Covers
Thanks for the favorable comments. The cat is out of the bag now. Jack P. and I had been waiting to post them till he got his on. Yes, I have the valve covers. I have the Short and Tall. V8 Choppers uses the perimeter bolt tall ones.The set on my BH trike and the ones Tom (PassNGas) has are perimeter bolt Chrome ones. Tom saw mine when it was at Bill Banks for my motor change over the winter and wanted a pair. He has basically the same motor as I do, 465 or 510 hp, both built by the same builder in NC and the only difference being the camshaft. Both have Dart Pro 1 heads. Jack Phillips has a pair that he is going to put on but wanted to get a set of Crane roller rocker arms before he put them on. He has the ZZ4 motor but has a pair of the conversion mounts. Jack has photos of both my trike and a BB of Ray Latham of Ray & Bev on the website. I have plenty of the SB and one pair of BB. I can do more BBs if requested. Everything is saved on two CNC machines. I enjoy talking about them so you can give me a call, Jack Hardy, (931)703-6312.
P.S. The tops are Lexan which will withstand the heat up to 350 deg. Yes, oil will shoot up (more like a splatter) on the underside but will shed off in less than 5 minutes. Do they leak? No. Mine were seeping at one corner on one valve cover and I tightened the screws after about 20 miles. No further problem. I also have extra tops and gaskets. If you drop a wrench on the Lexan, it is scratched. Jack P. said there was something you can get at the local airport normally used to polish airplane windshields which are Lexan."
If interested you can check your FBO at our Local Airport about Lexan/Plex Polishes. I haven't flown many Fixed Wing's with Lexan inserts, but from late 70, as an Army Helo Pilot/Test Pilot/Maintenance a be-zillion Helos run-up or Test Flown with Maintenance Issues (Leaks) and Lexan sheets/sheds Oil much better than Plex.
Very few Helo Gearboxes DON'T have Lexan Sight Glass', and I know it gets Real Damn Hot Vicinity the Apache Main Tranny, it has a pair of rather large GE Turbine's on each side of it, and a Turbine APU & Shaft Driven Bleed Air Compressor bolted to it.
I will Polish my Lexan throughly inside & out before I install them in the Covers. Then the Lexan will shed Ga-Fingerprints, drips, smudges better than the well polished shiny metal bits
The 1st 12 Pics are of Jack's Awesome Hot Rod Trike, the last 3 of the Red/White Big Block, well done Jack!
Jack, I got way involved with our Home Build in SC & have only patted my Trike's behind a couple times in passing. I found out IMMEDIATELY Someone has to keep track of the "Subs", they don't always seem to hire the best help (why is That footer Ditch 2' more shallow than this?). Thanks for you patience Jack!
The Brick Masons have the controls for a few days on the Foundation, then I'll be back there for them to Set the House.
