Post Hi-Rev SmallBlock

I have a Porsche 944, which I am installing a small block chevy. I'm looking to make the engine suit the nature of the car. My first thought was a flat/180-degree crankshaft(see prior post). Unfortunately, I haven't been able to find out much about building them.

The second option was a quick revving, high-revving sb. My thought was to get a 400 small block and de-stroke it to 348 cubic inches (327 crank?). My main concern was the heads. I figured if the stock heads could handle 6000 rpm for 400 cid, they should be able flow enough to accomodate a 350 at 7,000-7,500 rpm (without any head work). Of course, it will have appropriate cam, roller rockers, lightweight pistons, etc. Does this make sense or is there a better way? Thanks.

sounds good. that 327 crank will rev like no tomorrow, concider this... use 6 in rods and get your compression around 10:1. I've been getting the same engine together, down to needing pistons gaskets and berings(somebody makes spacer berings but can't remember who,got it written down somewhere) going to use a solid lift cam

I don't know exactly what you want to do w/ the car.But in order to make power through 7000-7500rpms you'll need head work and a massive cam,the kind that sound like a buffalo stampede.Big carb,Big converter etc....Not very streetable

Hey monte.
A much easier to build and very quick reving engine is a 377 stroker. I had a mild one in my Chevelle and it hit 6 grand real fast. A friend had a 377 in his truck and he ran it to 7200 rpm shift points with a set of X rods, stock crank. Never had a problem with it. Good luck. HG
