Really looking for comments on the dyno numbers. A little surprised perhaps that the power drops off so quick at higher RPM.

Guess i will need to look for the weiand inlet to replace the GM one if that proves to flow any better.

I really wanted a good mannered road which i can use for very occasional track use,

Currently working on getting some free flowing exhausts made up, with headers to route through the chassis rails (pics are a friends car with a ford, but you can see how much fun the headers are gonna be)

I just finished fitting the traction control, so that might help a little,
widest tyre possible in the arch is 285 on a 18 inch rim, they're on now

Have to wait for a couple of weeks till i get the engine, then i can finish up making the headers and we will see what it goes like

The ls6 was quick, i hope this will move a little more briskly

I don`t know alot about the L92 set-ups. Several people are having issues making power. Do a search and you will find alot of info. It does fall flat early in the rpm`s. From what I have read the cam you pick for these motors has to be right or it struggles! Good Luck and someone will chime in to help!

It makes some sense to me, a 224/227 cam in a 427 will sign off early. Good FWHP OP, that should make your 1,900lb toy move rather quickly

I think the numbers are right on . Should be a lot of fun

The Cam is wayyyy too small for that motor.You can run alot bigger and be fine for smog.A high 230's Cam would have perfect street manners and probly get atleast 80 more hp and stop the flat spot above 5k rpm.

your intake could be holding you back.and like was said,that's small cam for a 427.what's the ICL?

get ahold of Rick at Synergy. he has been doing some pretty good setups with the L92 heads.

1900lbs with the power it's making now...wow!

I read quite a bit on L92 package, and some had problems with large cams. I think youre putting very good numbers and that TQ in 1900lbs

Congratulations on this nice setup and good luck for traction

I am happy with the "area under the curve", what i really wanted was something that was not too cammy, and didnt need to be revved, as in these light cars you really can get in a mess when the cam comes on too quick and you constantly have to be careful with the throttle.

Love that solid low rpm torque, especially for the tight twisty roads we have here, you are through the gears so much, that using the torque makes these cars really fly.

I had a "cammy" ls6, and found it a real PITA to drive quick on the roads, it had little bottom end, and needed to be on the cam all the time to be quick

The builders (as you may have guessed from post 16 are Schwanke) and have done exactly what i asked them to do, provide a really mild mannered block, with a good amount of torque, and worked with me assembling parts I sent them (some from members off this board)

I guess as always, you look at a curve, and no matter what it shows, you always question if it could be improved, or if your parts choices are correct.

I would think a little peakier cam in the 427 would make controlling the power easier. With that much torque off idle it would come on harder than a little ramp-up to 3500 before it screams. I don't think any cam within reason in that big a motor will make it REAL peaky like a big cammed 346.
