Thread: Help me build my 355 street motor

Tweet

For SBC street iron heads with a non-roller cam, I don't think you can beat the GM Vortec heads that have been modified by Scoggin-Dickey with 0.525" lift springs and machined for screw-in studs and guide plates. Part number SD8060AGP, $388.25 each.

For SBC street aluminum heads, I don't think you can beat Air Flow Research 180 cc CNC Street Ported heads.

Get yourself a good, rebuilt, properly tuned Quadrajet. The tiny little primaries will give good throttle response and mileage and the huge secondaries will supply all the fuel/air mix that your 355 could ever want. If you don't know anything about them, order this book....

Don't choose a cam until you know your exact static compression ratio. Both of the cams you've chosen will be too short to work with 10.0:1 c.r. The motor will rattle like a can of rocks unless you run race fuel and/or pull all the ignition timing out of it, especially with iron heads.

Zero deck the block, use Fel-Pro 0.039" head gaskets and reconfigure your combination at 8.9:1 to 9.0:1. Then you can use either cam without a higher stall converter, although a looser converter (1,800 to 2,200) will get you "up on the cam" quicker and make the car more fun to drive.

That's my story and I'm stickin' to it.
