COMP Cams CL70-127-6 2.3 Ford Hydraulic Cam & Lifter Kit 1500-5500 RPM

Comp cam & lifter kit for 2.3l

I used this cam with the recommended dual valve springs, brake in grease, and 20W-50 oil and every thing worked great until the lifters collapsed and then it started to chatter loudly. I then put my stock lifters back in the engine and everything was good again and I still have not had any problems with chatter and lashing. However, after changing the oil from the brake in period and replacing it with 10W-40 the lobes started to burn and turn black. I would recommend using a heavier or even a synthetic oil while running this cam with dual valve springs and get a high quality timing belt. A cheap stock belt from the auto parts store is not strong enough to operate this set up at higher RPM's. The dual vale springs do help your engine run better and smoother then the stock setup but also has a much higher resistance making the belt work much harder to turn the cam. The only Performance timing belts I am able to find that will handle the pressure are all round tooth so I would recommend upgrading to a round tooth crank and timing gear set sold here at Speed Way Motors. I also added a long tube header, MSD 6AL ignition, a Pro Comp distributor, a EFI to 2bbl adapter with a 350 CFM Holey carburetor. Engine: 93 block, 86 D ported cylinder head with all the above parts. I hope this review helps those new to building Ford 2.3l engines.
