Vette vs. Fbody longblock??
Is there a significant difference between a 99 vette LS1 longblock and a 98 Fbody longblock? I know the vette was rated at 350 hp, but I didn't know if that was due to cam/head difference, manifolds, or just GM bs'ing the numbers. I thought I read somewhere that the 98 LS1 heads are pretty much the worst of the batch.

Same motor... numbers were bs'd...
Read the WHOLE thing not just the chart...
HP/TQ
And to tell if the heads are different between the two years, in the lower left of the top of the driver side head should be a number, if they match, they are the same casting.
