Re: Need Help!!!! 427 questions
Bore=4.25" (same as 454)
Stroke=3.76 (same as 396)
Internally balanced (like 396)
A good engine in my opinion. Often overlooked. A 454 will generally make more low end torque, but this is a Camaro not a tow truck. The L-88 Corvette version was no slouch and let's not forget the ZL-1. 425HP @ 5600 and 460TQ @ 4000. I knew a guy that ran one in a '61 chevy back in the '70's with 4.88's and a powerglide that ran 11's with street tires. I think he shifted at 7500.
