427 Chevy Stroker with RPM Intake & AFR Heads 580+ Horsepower

[arteche1]

Could a open plain intake and different cam yield more power and still be steerable on this type of set up?

@arteche1

Yes, a single plane and a larger camshaft will make more power. We designed this package for the corvette's and camaro's where hood clearance was an issue.

CHEVY BEAST!! how do determine the correct timing for an engine like that?

[cncmotorsports]

@crazylazy03

That's what the dyno is for, its a tuning device. We adjust timing and fuel curve for best reliable results. Typically most all Small blocks will be 32-38 degrees for total advance timing. Compression ratio, cubic inch and cylinder head type will affect the timing needed for the engine.

Very cool! Ball park, what would this exact engine cost?

[cncmotorsports]

@zachschevelle

The cost is $8299.95

Its an all forged assembly, with a brand new Dart SHP block.

What size stall converter would you need to use ? Thanks

[cncmotorsports]

@55chevyrp

I would use a 3000 stall.

[peaty427]

Do you have any information on the camshaft?

Specs: Dur @ .050"? Lift ?

I'm guessing just by the sound and output/rpm ... 245'ish and .615" ?

Also, is the intake ported?... or just port matched?

Thanks... it sounds real good!

Thanks

@peaty427

Sorry, I can't give out the camshaft specs, but the intake is port matched.

@tom69z28

The difference can be 50 horsepower. We spend a lot of time on the dyno developing our engines. As everyone knows the camshaft is a huge part of making that power. This is information we just won't share.

@tom69z28 You don't see the Nascar engine builders handing out flyers with their engine specs, do you? Those cams specs represent hundreds of hours of testing. Go buy some generic crate motor if that bothers you that they wont give you the specs.

nice ,, i have a set of Childs and Albert steel rods ,, not cap screw , do you think going over 3.8 stroke would cause alot of clearence issues , unless i went with a small base cam ??

[cncmotorsports]

@levisnteeshirt

You may have problems if they are not a cap screw.. This also depends on the camshaft size. Small base circle will help.
