i am looking at building my first bbc.the block is a 69 396 and the heads are 72 casting #3999241 just whant to know with the right port work are these heads a option.also any guess what the max hp and tq i can expect to get out of a 396 and drive on the street every day.faster is better.thanx jeremy
thanx for the reply every one keeps telling me i cant get any power out of a 396 and its not worth changing out my 383 6" rods 195 afr heads mowtown block.
Why are you porting them? There's already plenty of air in them for a 396. Use the search feature in this forum to see other 396 combos. Besides, if you don't have a flowbench to check your port work you could be making them worse.
I had the 2292's on a 402 and I now have the 241's on my 454.Both heads are identical IMO.Both had mild port work done to them and I had 219-1.88 valves put inthe 241 heads.These heads perform exellent for me.If you alreadt have them I'd use them.JMHO.Tony
