I was at a friends house tonight when we noticed something that we had over-looked for the longest time. I was under the assumption that GM started putting the 241 casting heads on the F-bods in 01, but tonight while looking at my engine closely, we saw the good old 241 stamp on the heads. I thought they were 853 castings for the longest time. Talk about a surprise.

I too just noticed my car has 241 heads. That made my day. How much difference in power is there between the 853 and 241 heads?

My T/A was a 2000 and had 241 heads on it. The vette I traded it for has 853's.

My 99 engine had 853's but my 2000 engine has 241's. It's nothing special most 2000's on have the 241's.

The 241's flow a tad more CFM than the 853's and usually make 5-10 more rwhp. Many tuners have confirmed this.
