Coast High Performance Emissions Legal 347 Short-Block

With 58cc chambers, the Windsor Jr. heads combined with the dishedpistons to pro-vide a street-friendly 9.5:1 compression. The large valvepackage allows all the breathing necessary at higher rpm.

When building a 347-E, you'll need to budget for the oil pump anddriveshaft. Coast has the parts, of course. The pump is a high-volumedesign at $41.99; the billet driveshaft is $19.99.

Coast carries its own line of budget oil pans and hardware under its ProMustang nameplate. The pan is a 7-quart deep sump (rear sump pans are$259.99; front sump "T" pans are $159.99), and it comes with the oilpump pickup and dipstick. Together these parts are available for FoxMustangs under one part number for $259.99.

We're excited about Coast's choice of intakes. The company is going withthe new Edelbrock Performer RPM II, which will give us some real-worlddyno numbers--when the intake arrives. By the time you read this, theseintakes should be out, but the first batch missed our deadline by just acouple of weeks.

Matching the Performer RPM II will be a standard 70mm Edelbrock throttlebody and EGR spacer. They will breathe through a Pro-M 80mm mass airmeter and feed 30-pound injectors controlled by an Aeromotive fuelregulator set at 40 psi.

The final tidbit is this set of polished valve covers. They are stockcovers that have been introduced to the polishing wheel, and they lookgreat. They run $229.99 a pair. 5.0
