desktop dyno 2k says this engine with an 850 carb and a single plane will make 525hp@6500 rpms and 469 ftlbs@5000 rpms. hot rod mag did a build up of this engine with a stock lt1 sized comp cam and made 412hp so i think it can make close to these numbers NA with a hot cam. heres the DD screen shot (copy and paste)

Expensive! And a waste of money.


I would not use and reworked parts, when you can get aftermarket component in just about any size you want.

 

thats a thought i had because i was worried about hacked parts as well. i just didnt know how much custom rods and a forged 327 crank would be. ill look into that.

 

Why make the engine smaller, bigger engines have more potential for making power.

You can get 6.0", 6.125" and 6.25" SBC rods for pretty cheap from lots of aftermarket companies. Then you could get a used nascar crank and run some custom pistons.

But why? There is no reason to build a small engine unless you are liminted by rules.

 

becuase like ive said in the past, im interested in something that likes to rev. i dont want killer low end and then a sharp drop off of both hp and tq like the TPI has. i was something along the lines of an ls1 style powerband.

 

If you want something along the LS1 powerband then it will almost just as cheap to go buy a used LS1 and all the goodies to hook it up. There are plenty of articles to the swap.

 

So, what does all this custom crank and foreign rods and reduce the motor's size, have to do with that? "Revs", by which I assume you mean the torque vs RPM curve, aren't determined by the short block; they're determined by the induction system and the cam.

But even apart from that, what do you really want here? Do you want some arbitrary imaginary spank-off about "power band", or do you want to go fast?

If you've got a 400 block, then build a 400, put the Stealth Ram on it if that's what you want, and be done with it. If you pick the right cam and heads, the power band will follow. All the rest of that custom crank crap is just 3 steps backwards for every step forward; and consists of using your own money as the weapon to shoot yourself in the shorts with.

 

Here we go again.
