T/A Perf Alum Buick/heads update
The first production run of blocks is underway. They have been cast and are in process for machining. Other items like liners, plugs, caps, etc. have been ordered so they can be assembled. Many deposits have been received so this production run is almost sold. Anyone wanting one, should get in line now. The next run may be late this year or into next. Delivery will start in about a month.
The design and patterns for the heads have been released for pouring the castings for the first sets. The one casting will be used for Street Intimidator [SI] stock-type heads and Street Eliminator [SE] 14 bolt heads.
The SI heads will use a 13/16" rocker shaft like stock or roller rockers. Ports will be matched to stock intake and exhaust gaskets. The valves will be SBC 1.94" intake and 1.60" exhaust with spring installed height of 1.90".
The SE heads use the same valves but ports are matched to Felpro 1200 intake and 1400 exhaust. A steel "stand" will be used for 5/8" rocker shaft and specific rockers will be needed for correct valve train geometry and operation since the valves/stand have been moved from the stock location for better much flow.
Both heads are made extremely strong with about 5/8" thick combustion chamber dimension. They have been designed to RELIABILY develop 1200+ horsepower.
I should have a set of pre-production within a week for final assembly and flow testing. They will then be installed on a street GN for testing and fit. Plans are to have a production set available for the Norwak and Bowling Green events in May. The data of flow will be posted as soon as available.

I said nothing negative what so ever..... you need to learn how to read what is there!
Christ, you don't even build your own motors or do any of your own wrenching so back under your rock. Didn't need your comments at all. Funny how someone that hasn't even ran out of the 12's talks ****
