This camshaft features a 235/249 duration split designed to produce a deep, lopey idle while maintaining strong mid-range torque and excellent throttle response.

Key Features:

  • Optimized for street performance with enhanced sound characteristics
  • Compatible with Ford 351 Cleveland, 351M, and 400M engines

Good

Took a long time to ship. But was a great deal for the price of the product will order again.

Was linked here by Amazon. I found the absolute best price on the item I was looking for, I had a confirmation as soon as I ordered it, and shipping as prompt. I would definitely recommend these guys and will be shopping here myself in the future.

great

"Excellent price and great customer service. Order was shipped promptly!! Would do business with them again. "

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

Item arrived promptly (4 days after order), price was good and item was as described.
