I can tell by the packaging that they are a Morel lifter. Let me know how much you have to machine off the top of the lifter bores LOL

Those will work fine in your block!!

The problem with a Vortec roller block and a high lift camshaft is the lifters dropping out of the lifter guides when on the heel of the cam lobe and the bottom of the lifter flat hitting the lifter guides at full valve lift. That concern will apply to any camshaft with more than 0.350" lifter rise and a cam lobe base circle smaller than 1.150" O.D.

Since you chose retrofit link bar lifters to use in a roller cam block you will not have a issue with lifter guides. I see no problem if the link bars do not hit the tops of the roller lifter bores when the lifters are on the base circle of the cam lobes.

The Comp Cams camshaft in my engine has 0.334" lifter rise and 1.190" O.D. cam lobe base circles. No problems.

Crane Cams 10535-16 is a longer roller lifter for use in 1987-1999 4.7L roller cam blocks. Those lifters can solve the problems when using as camshaft with lobe lift greater than 0.350" and cam lobe base circles less than 1.150" O.D. Those roller lifters cost about $700 at Summit.

The Morel lifters are .300 taller and will work just fine. Guys use thse in the SHP blocks all the time with out any issues.

These can be used with more than .530" valve lifts and engine speeds above 6000 RPM. They are designed to be used with early SBC blocks that have short lifter bores for link bar clearance. The tops of the lifter bores must be machined to fit these lifters if usimg a roller cam block. .

I'm just glad I didn't have to pay 630$ for them!!

Despite the fact that I bought them over a year ago and they have been collecting dust since then JEGS was very cool about letting me return the "ls7" lifter kit with tray. +200$ All in all, I am happy spending 300 more bucks on the lifters I have now. No sheet tin tray to worry about and I can run a large cam later if I so desire. Hopefully they will not be as "ticky" as the ls7 lifters also.

I have been reading posts on this forum for over 7 years and I strongly believe EVERYONE has some knowledge to offer. Sometimes guys get mixed up on things. It happens to all of us!

Many thanks to CNC and mousefink both, because, without debate these posts can be boring!

Sorry, I misunderstood what my engine builder told me three years ago. I called him to clarify what he told me and this is what he said:

"You must use the correct roller lifters for the block you have. When GM went to roller cams in 1987, the Vortec blocks were cast with taller lifter bores for the tall O.E. roller lifters, anti-rotation link bars and the link bar retainer. You can also use after-market tie bar lifters. But for 1986 and earlier blocks, you must use special retrofit roller lifters that are designed for the shorter lifter bores."

...is this how you talk to people in real life?

If so, its not allowed here...PERIOD!

Last warning I'm going to give you, I've given you enough rope in this thread.

Stick to the OP's question and not what other people post in a thread, everyone tries to help the best they can.

Thats what internet forums are for, it's not a school yard. You should know better by now.
