400 sbc street combo

Anyone want to share a good street combo in a 400 to 406 sbc? Prefer to shift at 5800 to 6000. Torquey combo.

67 chevelle malibu / SS/ custom

Currently undergoing a metal work to remove all rust, if I ever get there.

Cant decide on prostreet or cruiser with a 4 speed.

Re: 400 sbc street combo

Well, I'll start. I'm going through the same thing right now. I have Mahle 16cc reverse dome pistons, 6" H-beam rods, factory crank. Going to put Brodix IK 200 heads on it, 10.4 c/r and a hyd. roller around 235*

Jeff, sounds like a solid combo and something Im expecting. I was thinking about the IK200's. I ran the IK180 on a 350.

What are you expectations as far as power?

Re: 400 sbc street combo

I was going to build mine with flattop pistons (6.0" rods) and AFR 75cc chamber heads - 10:1 compression. Had a Howards Hyd Roller ground on a small base for clearance (they picked the cam with my engine specs). Unfortunately my block came back with a crack, but I can run the parts in a 383

Hoping 450-475 hp / 475-500 tq, but those numbers are just a guess. I'm sure others with real life combos would know for sure.

Make sure your heads that you intend to use have steam holes drilled into them.

2v relief flat tops
6.0” I-beam rods (good cam clearance)
Factory crank (just don’t need anything more at this level)
292H Comp

Etec 200 or anything close. Can use small chamber 461 2.02/1.60 or similar (Performer or RPM) and trade some hp for torque.

RPM intake, 750 vac carb.

Sounds like the shortblock I have in the garage except I will use 062 Vortec heads. More HP with less porting work.

Re: 400 sbc street combo

flat tappet hyd 280 adv on 106 is a great super torque cam for a 10 to 1 406. lunatic used to make some great tight hyd cams that would just scream in a 406. we had one that ran 11 0s at 125 driving to the strip with 10 to 1 406 with 220 brodix heads. this was 20 years ago

I always wanted to try a Track 1 M2-215, or an AFR 210, and a solid cam but it was too rich for my blood.

The E-Tecs 200s really made me smile, and I kept the same cam. Good torque and the engine would still idle in gear at 450 rpm with the Comp 292H. Low end torque was/is fantastic. It’s still running 21 years later in my best friend’s ‘65 Chevy II. Probably makes about 445 hp, enough to run 11.93 @113 with 3.08 gears.

Re: 400 sbc street combo

I originally ran the L-79 cam in my 406 with -186 2.02/1.6 valves. It was incredibly torquey.

Re: 400 sbc street combo

hi

The afr 227 version I mentioned has 4500 rpm stall,over 12:1 CR big Hollley manifold , 4.3 gears , and 275 50 15 rear tires . Weekender a lot of drag and some street use .

The 220 heads if u use a 240+ cam vacuum might be an issue.

The friend who built the 227 headed 400
also built
383 street head 195afr mid range SR 540hp
400 street 210 afr head only slightly more hp than 383 by 10-15 hp . Bigger SR cam and Big holley manifold 580 ish HP gain of 20-30 hp.

Which ever combo u need the right convertor and gearing to match is essential
