"Everything bolted up good with no modifications necessary," says Sean Baisden of Harv's Auto & Dyno Tune. "All the components went back on without modification, which is pretty unusual for aftermarket parts. It made good power--the power they said it would make--which again is rare for most companies. I would definitely recommend to somebody looking for another 30 or 40 rearwheel horsepower that they look into the Edelbrock upgrade. It's a near perfect combination. It's also a good basis for additional add-ons. For a stroker, I'd definitely want to port these more or wait 'til the bigger 200cc heads come out."
