273 Supercharged...ITS HAPPENING PEOPLE!!

So since the last I have posted things have been moving along slowly. Until I have all the numbers and measurements in front of me I will just say we are boring the block (after sonic test) and using Chevy 305 Rings. Still custom piston. Going to roller cam and lifters, possibly rockers. All progress had to halt until we worked out the bore size. Custom rings would have been another insane expense, Although at this point its all silly anyway.
We had a conversation about staying with the super charger. Its the easiest to do but I have been researching the down sides. The whole point of this build is to build an engine that is fun on the street. So power really high in the RPM range 3500-6000 and a small CI engine i'm afraid it would feel like an import. So the thought is that I can purchase the stuff to do a twin turbo set up for the same cost. just have to add the time to construct. In the end a pair of 58mm Comp turbos would spool quick and bring the power back down to the 1500-5000 range. So thats the way Im leaning. Probably going to use regular manifolds and just run two pipes up to the front to mount the turbos. long way to go still. Transmission and engine parts should be back in a few weeks. Then the fun can begin.
