Parts selection for sbc 400

Doing some window shopping, while the block is being checked out.

What you think of parts selection for a 475 to 500 horse 400 SBC with around 500 torque?

The usage of the car is just a cruiser. Not on the track at all.

Unsure if I need to go internal balance or not.....please chime in.

If I go external balance here is a kit that Im looking at.

Here are the heads I would be using.

Brodix 200 IK

https://brodix.com/heads-2/small-blo...eads/ik-series

A roller cam is going to probably be out of the budget. Im looking at this camshaft from Mike Jones.

284/288 and 228/230 @ .050 for .528/.528 on 1.6 rockers on a 110lsa or something similar.

Topped of with a Edelbrock RPM and Holley 750.

Set of 1 3/4" headers.


Can I get there with this parts?

Do I need a roller in there to get to the desired power level?

Opinions on externa or internal?

Remember its just a street car.

Re: Parts selection for sbc 400

The Eagle link did not go to a kit.
To me the components would fit a 383. I would step each up one notch for a 400. The intake choice is ok. 10.5 compression. No need for the internal ballance expense. Spend that money on 6" rods, Mahle pistons and having the heads rechecked. All the while upgrading the cooling system.

If I were to take the 406 in the race car and toss it in my cruiser, the only thing I would change is the cam. I would use my CC 282S and that would be it. You will not need a roller to get an east 450 to 475hp out of a 406 with the heads you plan to use but you may find that the RPM intake might not cover the tops of the ports on the heads. The Air Gap I think is taller in that area.

The Eagle link for some reason cant be fixed.

Its their part number 13011.

You advise to set up the cam one notch? What is hard, is trying to match a cam to the compression of eith a 64 or 70 cc head.

You have other ideas on a intake?

Heads would be bare and assembled by a head expert.

Cooling is already addressed. Using a big aluminum rad.

Good to know about the RPM.

What kind of combo would produce 500/500?

I based my unfinished 400 build up of of a article I saw years ago in one of the mags, they claimed to make about 485HP with a 400 using AFR 210 heads, victor jr intake, and a Crane hyd roller pn 119841 grind HR-296-2s-12 IG adv dur 296/304 0.050 dur 234/242 Lift 0.574/0.595 with 1.6 rockers 112 deg lobe spread.

I ran into money problems so it is still unfinished. When I do finish it I will be using my old afr 195 heads.

WOW! I would think with those parts you would of gotten well over 500 hp. Lots of duration on the seat for a hyd roller.

Yes, I know what you mean about money.

Im trying to get the most bang for the buck.

I think the the article was done just before the afr eliminators came out not sure how much a difference there would be with the afr eliminators

Do you have flow numbers on your heads right now?

Looks like in your signature, your 77 camaro build will be similar to mine.

I see.

Those flow about the same as my Trick Flow 195 heads on my 530 horse 383 in my s10.

I also have a set of Dart Conquest 200 heads on my Dads 383. They have a 2.08 valve in them as well. Probably overkill for a driver though. They flow similar.

I think your going to be around 500 with that combo.

I would be happy if it puts out at least a nice 475hp with accessories and exhaust

No air conditioning.... just power steering, power brakes, alt, water pump. Hooker 1 3/4 headders and I am going to get a 3 inch dual exhaust with a straight thru muffler like the hooker max flows that I had on my 81 camaro
