Heads for a 406 street engine
Looking to get a set of heads to fit a 475 to 500 horse 406. Nothing fancy, its just a street engine for cruising. I have been looking at MCSA and checking how efficient they are based on Coefficient of Discharge math. I still very new to the game and still learning, so be kind in your replies. Im n...

Re: 400 SBC build
If I understand how to calculate CSA and Port Volume for a engine, this is what I came up with. For a 406: 6000 rpm CSA = 2.23 6500 rpm CSA = 2.42 This leaded to figure out my 406 port volume: 6000 rpm port volume = 200 6500 rpm port volume = 216 So, based on this information, if I plan to turn the ...

Re: 400 SBC build
This is all great information. I just got back from the machine shop and block is already .040 over....so the machinist says its junk. Back to square one. Looks like if I want to do this, a 400 SBC build...going to have to get a new aftermarket block. Why is he calling your block junk at .040"...

Re: 400 SBC build
All of those cams will be fine at 1/2 point less compression. The 1/2 point difference might show up at the drag strip, but for a street vehicle it would seem like cheap insurance. I understand the reason to take out 1/2 point of compression. However I fell like that is to much, maybe settle on 10....

Re: 400 SBC build
Well, Im down to three cams. Not sure how they are going to work out with my 10.5 compression, but here they are. All are flat tappets.

Re: 400 SBC build
Even though it’s tempting I wouldn’t aim for a specific hp number. For a street car it doesn’t matter if it’s 450 or 500 hp. I would aim for a mild mannered engine with broad Powerband. You should still be able to make burnouts for distance Yes, I agree. Just trying to make sure I can get as much a...
