Camshaft

[Aron Gleason]

I have the purple shaft 284 484 cam in my 440. Would i have any clearance issues running the isky 292 505 cam?

The determining factors are:
-Which pistons you have, and their deck clearance
-whether you have adequate retainer to seal clearance
-how much the heads have been milled

If you have pretty much any piston with valve pockets, that part of the equation should be fine.
Same if you have a late model engine with the pistons down .100+…….unless the heads have been milled a bunch…….then it becomes “maybe”.

Retainer to seal clearance……..max lift +.050”.

I have the L2266 pistons, 906 heads. Nothing has been milled or decked.

My block is a '68 440 hp block. And is there an alternative lifter to use other than isky lifters that don't cost $450 for the hydraulic lifters?

You can use any lifter you desire.. but the real question is, which ones are good?? I'd hate to see cost force you into a sub standard lifter.

$450?
That’s a “nfw” for me.

If the current lifters are fine, I’d look into having them refaced…….and reuse them.

L2266 are about .080-.090 in the hole. You should have plenty of room. I have run .528 lift with no problems. Im not sure if you have enough retainer clearance though.

I passed on a set of Mopar ,Comp cam hydraulic flat lifters at the swap meet today. New in the box with a 2014 date.
Guy wanted $80, I was not sure when the steel went to crap on them.

I would have picked them up at that price and had them checked for proper taper.

Have your current lifters refaced. The 284 & 292 cams have similar specs. The 292 will have a rougher idle & less low end tq.

A couple lifters are concaved. Not worth getting them refaced.
