Gear drive
 

So thinking I was doing myself a favor and getting an amazing deal, I purchased a new Jegs noisy cam gear drive, Trans Dapt Slam Guard oil pan, and a billet bow tie timing cover, all brand new, for $120 bucks.

When I got home, I realized the oil pan was for a passenger side dipstick and the gear drive said for factory roller cam :icon_doh:

What's different about the factory roller cam gear drive?

Do you still have a functioning knock sensor? The harmonics from the gear drive picked up by the knock sensor will screw up your timing.

No, no knock sensor. So will this work on my engine? It's a 1974 350 4 bolt with a flat tappet hydraulic cam.

No it won't work. A roller cam engine has a thrust plate that bolts to the front of the block over the cam. Front of the cam design, as well as the cam gear is different: Roller & Flat Tappet Cams

Ahh, I see now after looking at the differences. Thanks!
