anyone know how much a 400 (511)
big block with aluminum heads and a 727 weigh? just got a new roller and was wondering what it will weigh with everything in it, 2100 with no motor and trans

Around 600 was our 400 based 452 with Edelbrock heads, performer rpm intake, 950 HP carb, 143 tooth flywheel (29 pounds), softlock clutch and disk, Lskewood scattershield. The 600 is from memory but close. I used my Spinlock load cell to weigh it which is very accurate but that accuracy does you little good if you do not write it down .

When it comes back from Performance Only I am going to weigh it again. It will have a different intake though with a Weiand Tunnel ram and 2x600's and the flywheel is now alumnium. Ask again in a couple of weeks to remind me.

I imagine the flywheel and clutch will weigh about the same as a torque converter full of fluid. An auto has a significant amount of weight in liquid. If you know the weight of a 727 you should be close. That weight I gave is without headers.

thanks for the info!! I just traded for a new car and was tryin to see if its worth putting my good engine in my challenger, it weighs 3850 race ready and from the looks of things this car should be about 3100 race ready with much bigger tires!! not a 100% on what 750lbs will do to the et but should be real good it runs 6.40 on motor now
