I'm in the US, and building a Duratec for a Pro-Challenge Mustang road racer.
It's a tube-frame RWD car, running a T5 trans and a Winters quick change rearend, with a race weight around 1900-2000 pounds with driver.
I called Crane Cams yesterday to ask for cam recommendations, and it seems they have discontinued supporting the Duratec.
I wonder if anyone could recommend cams and valvetrain for my build.
The block is a Ranger 2.3, with a modified Forged Ecoboost crank, Molnar Technologies forged rods, and Wiseco 12.5:1 forged pistons.
Oiling is via a Raceline internal dry sump, with a Concept Racing 1.5 gallon tank, remote filter and cooler.
The head is from a Duratec 2.5, casting # RF8E5E from a 2010 Ford Fusion, and I have modified the oiling system to eliminate the VCT and feed the front intake cam journal from the main oil feed instead of through the VVT system.
The head will be fully ported, with 1mm oversize intake and exhaust valves.
Intakes will be 50mm ITB's, and due to space limitations in the chassis, we're designing a billet intake that will place the throttles as close to the port as possible, and angled up approximately 45 degrees or so.
I plan to fabricate an airbox over the airhorns, and duct cool air from a remote filter behind the grille.
I'm aiming for peak power to be around 8,000 - 8,500 rpm, with a redline of 9,000, and would like to see over 300HP if possible.
I see cams from Kent Cams, and Cat Cams, but don't know much about either company.
I do like the Kent Cams design, which comes with an adjustable sprocket as standard, and gets rid of the single bolt/friction washer setup, but I need to make sure they offer them in 38 tooth to match my oil pump and crank gears, and chains.
Anyone with experience, I'd really appreciate your input.
Thanks,
David
