I have a generation V cam for a 420 HP engine and I wanted to know if it could be used in a generation VI engine?

GenV block is a set up for a flat tappet cam, Gen VI is set up for a roller. The snout on the cam is different and also the timing chain is different. Why would you want to use a flat tappet cam when you could go roller?

The cam could still be a hyd. roller. It would be the same cam as a Mk IV.

Ohio,
Just be sure that you set the end play of the cam. With a Gen VI, you don't have to because the cam has a step nose that uses a retainer plate to keep the cam from walking. You will need to use a cam button to control how much the cam can walk forward. Ideally, you want .006-.010". Good luck.

The gen 5 blocks have the step and retainer plate also. I had a after market hyd. roller in a gen 5 block and switched it to a gen 6 block no problems.

The Gen V block has the provision for the retainer plate, but it did not use it from the factory since it didn't have a step nose cam. However, you can install a Gen Vi cam in it and use the retainer plate. You can also do that in a MK IV, Dart, and Merlin blocks. They all have the bolt holes at the front of the block. You just need the step nose cam.

Our 96 gen V hp 500's had step nose cams in them.

Young Performance

I'm sorry. They put them in the 500's because they used different cams and retrofit lifters. I think the 500's were the only Gen V to get that. All of the Gen VI's had a step nose cam since they were factory hyd. roller engines.
Sorry for the mistake.

Years ago, when the 502 V first came out, I ordered a short block from the GM dealer... It came with a cam in it, and was not suppose to per GM. Found out later it was one of 12 released that day and they were not available for a short period after that for a few weeks or months. I was trying to find a flywheel for it and found out the info the short blocks from that day..
Anyway, it had the straight cam without the step.. Back in the day, I believe there was a lot of mix and match and confusion as to what was what.
The next year the VI came out..
