Hey guys I'm new to the forum and looking for some help. I'm looking to build a stout 406 sbc for weekend street use with some drag racing as well. I want to make around 550whp. I would like to hit that number n/a but also possibly interested in a turbo build. Originally planned on a twin turbo ls1 in this car but plans have changed.

I need info on a good block to go with (ive been looking at the Dart 406 shortblock) I also have no idea what heads to look at and I want a nice choppy cam. I plan on running a th400 trans with a 3200-3600 stall. Probably going to do a 12 bolt rear with 3:73 gears.

Any help and tips would be greatly appreciated. thanks guys

If the question was 550 hp at the crank then I thing a lot of answers would be out their. But 550 at the rear wheels is a different story. 550x20%=660 at the crank NA. With a power adder then its a lot easer to do. Now start with a after market block and add a stroker kit ( something like 434 inches)and good heads and some compression and the right cam and it becomes a lot easer.
