Re: Opinions or experience with ISKY E-Z roll lifters
 

Been running Isky EZ Roll X solid bushing .904 roller lifters for the past 3 seasons in my Dart Big M block without issue, seeing 8000 in the lights every pass.

There are alot of threads on Yellow bullet interference to sizing issues.

Had a customer last year I machined a Dart block for his sprint he sent me new bushed ISKY.904 lifters and customer had to get with ISKY to get the sizing issues straightened out.

Its on MY F/B paged if you need to see it !!!

Don't get me wrong ISKY Lifters are great lifters but having to buy 2 or 3 sets to make up one set is a PIA.

There are a lot of engine builders who really don't care about lifter size and just dump the lifter in the lifter bores with out checking clearances.

Now ISKY does sell the Durathon lifter which I have never had to send back or get 2 or 3 sets to make up one set but those lifters are made by Morel and size seems to be very good.

This is the problem when lifters are not fitted.
