Gents,
Thought I'd share these with you...
Most of my engine components are with 'a man' being balanced, seats cut, vapour blasted, ultra-sonic cleaned, etc. Hopefully engine re-assembly will commence soon. Here are some pics of the various bits n' bobs going into it. I know a lot of you guys already know this stuff, but hopefully it will be interesting to some:
Here's the JS wrist pin compared to the stock pin, its approx. 29% lighter and DLC coated...
JS Carrillo conrods vs stock, the carrillos are simply things of beauty! Overall they are slightly heavier than stock (only slightly), but the little end is lighter. But then, they are approx. 1/2 longer (to suit the short pistons) and are (hopefully) unbreakable (I have broke a stock rod, I'd like to avoid it on this build)...
Cam followers, photo doesn't do the difference justice, but the JS supplied BSA followers are approx. 1/3 lighter. Plus, I am convinced, the radius improves cam oiling...
JS stage 1 cam versus stock. The machining of the cam is truly excellent. It doesn't have a huge amount more lift than stock (0.030" ish I think), but does have quite a bit more overlap. I was very tempted to go for 'more' with the stage 2, but repeatedly advised that this is best for road use. I can only hope so...!
Pistons. Ah yes, the pistons. The piston on the right, is a stock bore Omega racing piston with a crown raised 0.100" over stock. The piston on the left is a +0.020 JS piston with a crown raised 0.110". Despite this, the JS pistons looks tiny! It is approx. 1/3 lighter than the Omega. Frankly, I think it makes the Omega look like something out of a tractor. These JS pistons are just beautiful...
I have to say... and it isn't easy to do so being a Brit... the stuff I've had from you Yanks (that's Jim Comstock, Jim Schmidt, and Matt at CNW) has been pretty bloody impressive. Hopefully, it will all continue to impress once it is all installed and the throttle is pinned to the stop...!
