4 Red Goldstein of SSRE slides in the hydraulic roller camshaft, which is part of the HHR upgrade package. It also includes hi-rev roller lifters, Comp 1.6:1 roller rocker arms, and AFR 210 aluminum heads (with springs to match the hydraulic roller cam profile). No amount of pleading could convince Shafiroff to reveal any of his cam specs.

One thing that separates the Inglese system from other individual runner setups is the common plenum, which dramatically improves the driveability and torque. For those who want an even cooler looking Inglese setup, we saw one manifold in the company’s SEMA booth that had a direct port nitrous system plumbed into it. We asked SSRE about adding some juice and they said a little hit wouldn’t hurt the engine and custom setups can be built in-house.

Every engine that leaves SSRE is run on dyno and all Real Street engines make within one or two horsepower of the advertised ratings. This setup spun the DTS dyno to a peak of 566.5 hp, right on the 565hp rating as advertised by SSRE with the HHR upgrade option. That’s within one horsepower of the carburetor version that uses an Edelbrock dual-plane intake manifold and Quick Fuel carburetor. Scott Shafiroff credits the near identical results of the packages to getting the most from the cylinder heads and camshaft design.

The Real Street EFI had a peak reading of 586 lb-ft while the carburetor version typically cranks out 585 to 588 lb-ft.

Reliable, simple, and unique are the perfect adjectives to describe the SSRE Real Street EFI crate engine and it all fits in nicely with that familiar term--powerful.

6 The crankshaft is also measured to ensure any problem is caught before assembly. The Eagle crankshaft is a forged-steel unit with a 4.00-inch stroke, bringing the cubic inches to 427 when combined with the 4.125-inch bore.
