Chas, steel splayed on the middle caps.
gsharapa,
You'd have to buy a lot more than an intake and a distributor to get that puppy running. I have posted complete turn-key engine deals on here with a lot more bang for the buck. (My complete engines are also fully dyno tested and you get the dyno video/dyno sheet with the engine.)
I also am known across quite a few high traffic websites on the internet. I would have to make right on a customer service issue (not that I wouldn't anyway), or my business would go down the pooper in a heartbeat.
So, have your engine built on an assembly line by guys that have high quotas to meet...or have your engine built by a picky mechanical engineer who supplies a CD with build pictures and a spec/clearance sheet?
And who wants just 535hp?
