Hello everyone,
I was thinking about swapping out the small block in my car with a built 540 big block gen VI motor (4.25 stroke, 4.50" bore), as my car is just a weekend hobby and not a daily driver. I am planning on using a gm bowtie block and all forged bottom end, hydraulic roller cam, mild aluminum heads. I am looking at 550-600 horse and tons of torque. Can the C3 handle the torque and what about the rest of the drivetrain. Is the big block too heavy for this car? It should be a bit lighter with aluminum heads. I did notice they sell an ZL1 aluminum block (it's only like 100 lbs), but it is over 4 grand just for the block. I am really intrigued with the big block lately, I don't know why. I really love my C3 btw, this car has great lines!
Thanks & Happy Holidays,
Ed
