Thread: SBC 400 Parts & Suggestions

yeah just go the 030" over route your better off. stroker motors are a pain jmo though.

Ok i was looking at a wholesale book at work today and i scouted some prices.

1 Scat series 9000 crankshaft (3.75 stroke, use with 5.7 rod) = $203.99
1 (Eagle) 5140 steel rods (5.7") = $174.99
1 Set of Speedpro Flat top pistons (hypereutetic)= roughly $200.00

Then if you figure about 200 bucks for a set of main bearings/rod bearings/rings I'd have a complete kit with everything i'd need to assemble the short block for about $800 by the time i got a gasket set so i could put my oilpan/timing cover on it. I figure thats a pretty good deal? Those pistons and rods press fit.

Here's an answer I gave on another forum to a fellow who has a 400 to build....

Quoted from Car Craft, describing a motor combination.....
"That engine was a 406 ci small block with Vortec iron heads, an Edelbrock Performer RPM Air Gap intake, a 750 Holley double pumper carb and a mild Lunati hydraulic flat tappet cam. The single-pattern cam spec'd out with 230 degrees of duration at 0.050" tappet lift, 0.480" lift and a 109 degree lobe separation angle. The engine was also fitted with small 1 5/8" headers and on Duttweiler's dyno made an amazing 525 lbs/ft of torque at 3,500 and grunted out 471 lbs/ft at 2,300. Horsepower was acceptable with 428 at 5,000. The limiting factors to more horsepower were twofold. First, Vortec heads are exhaust port limited, so using a camshaft with about 10-12 degrees more exhaust duration and a little more lift would have helped. Second, to accomodate this additional lift, mods to the heads would be required with better valvesprings as well. You can purchase a set of Vortecs already modified with more retainer-to-seal clearance and better springs (PN SD8060A) from Scoggin-Dickey for $680 ready to bolt on. As for the cam, we'd go with a flat tappet hydraulic cam with specs of around 230/240 @ 0.050" with lift around 0.480"/0.510" and a 110-112 degree lobe separation angle."

If using 5.7" rods, you'd want to use a small base circle cam and longer pushrods. Using a KB168 Keith Black piston (22 cc dish), zero deck, 0.040" compressed gasket and the 64 cc Vortecs, your static c.r. would be 9.78:1

Remember to drill the Vortecs to match the 400 block steam holes and use a 400 head gasket.

Bolt a 2,500-3,000 stall converter to the back of this motor with a 3.73 gear in the rear.
