I`m sending the cams and lifters back to Comp today for inspection.They offered to replace cams and lifters for free or at a greatly reduced price after they inspect them.

Any recommendations on cam profiles? The motors are 454`s with blower pistons and 671`s with superchillers

Was running grind # 3376/3377 gross lift .613 intake and exhaust. Duration at .050 intake 240 exhaust 250 with 114 lobe separation

With this combo it would push my 1989 Top Gun to 5800-6000 spinning 25p Mirage Plus props.

At this point I am looking for a more reliable set up and I`m seriously thinking of going back to hyd flat tappet cams.

Thanks for the input guys!

Kurt don't do that ,,stay with the roller just install the right stuff
not that you did not try before .. but in a 741 crane and isky lifters and let me know what pressures the springs are on ,,I'll try and help its easy and done everyday don't throw in the towel

I agree with Bobby, you will only be going backwards. Listen to the master, he knows.

Wow what a shame
Biggus has one of the sweetest guns made
Since the block is junk why stick with the Gen 4?
These cam lifter discussions are good for me right now my motor guy was saying he liked Isky and this just suppoorts that

Klaw, thanks for the compliments!

I`m sticking with the Gen 4 because the stbd motor is fine and I have another block and heads ready to go.

What are your thoughts on running another Comp Cam (since I`ll be getting it for free) and using Isky or Crower lifters?

bobby daniels

Biggus the 5800 to 6000 is bad for the hyd they blow up at that
really they weigh to much for the springs to control ,,the springs for you need to be heavy duty isky tool room springs and they and the isky lifters will last the comp cam is ok but put it in 4* advanced or even 5 and prop it at 5700 max 5600 is better ,trust me it will live and work

I was waiting to hear comment on anything above 5600 rpm
starting to break hyd. rollers down.

Would you recommend Solid rollers to him with his set-up
so he can still run the R's ?

Or is he better off staying with that?

By the way Bobby have you had a chance to get a picture
if ISKY's design yet on rollers?


Thanks for your continued help
