FWIW- I had a 355 CI car with a 233/239 cam w/stock heads and intake. The car weighed 3700 lbs with driver. The crank was 10 LBS less than factory, the rods were light weight rods, I had the fidanza flywheel, aluminum driveshaft, 3:73's, and a spec 4 to boot. I ran 7.93 on engine and 7.0 on gas. I drove the car everywhere!!! If you roll race any it really shined, but also preformed on the track.

I see. Was the rotating assembly balanced with the new pistons and rods? If so then I would check the flywheel to see if the weight it there. I've never looked at a McLeod but my Spec flywheel has a removable weight that is held on by 3 bolts. I would expect similar on the McLeod
If anyone is interested in a McLeod let me know I have one for sale (w/o the weight). Cheap!

Check your torque multiplication ratio first. Trans first gear x your rearend gear. If it is above 11 you will still have a drivable car anything below and you don't have the gear to make up a decent launch. I am putting a Mcleod twin in my chevelle and spent a lot of time researching it. I ended up with an aluminum Mcleod Flywheel/twin disc setup good to 1200hp (took 5weeks to get). I am running a blown 406/ T56 6sp/ 4.88's w/locker. This puts my torque multiplication up in the high 12 range my old combo was in the 8s and would have sucked . Haven't got to drive it with the new setup, but Mcleod had said the 1-2 shift will come up quick, accelerate like mad from corners, and it will be Hairy. Pick your poison, but remember the motor won't only accelerate quicker it will deaccelerate just as quick.

Just remember it will be real easy to stall of the line and you will have to be more aggressive with your shifts, like shift at a higher rpm because the r's will try to drop (deaccelerate) more between gears or shift faster. I say go for it and let me know what you think. If you don't like it just change your rear gears and you will!
