.033 can be reamed, then honed out of the lifter bosses.

That's where I'm going to start to lose interest. As more things have to be modified the costs start to go up and the difference between this and a retrofit lifter starts to come closer together.

Plus you're modifying the block beyond no return which makes it useless for stock stuff, and it's not something most here would want to convert over if it requires now taking the block to a machinist just because a guy wants a roller cam.

I'd only be interested in this type of deal if a drop in lifter can be found to be used.

What is the difference between reaming lifter bores to install bronze bushings to correct lifter geometry or reaming then honing a lifter bore to install larger diameter lifters? In my opinion there is none. IF someone wanted to return to the OE diameter lifters it would be a simple case of installing bronze lifter bushings to return the bore back to standard size.,

The difference is that now you're talking about stripping a block, pulling the engine, and getting machine work done for anyone that wants to swap over to a roller cam that can normally be done in an afternoon. That's a huge turn off.

That's not even taking into account the added expenses.

And what about the Olds 307 lifter mentioned earlier? Same diameter as Pontiac? Oil band in the right place? It seems it was dismissed earlier in the thread...

Kinda hard to do with a assembled motor in the car also.

Yep

The ht2148 sealed power lifter works. With the ford style dog bone and a .335 lobe lift the barrel does not come up far enough to hit the dog bone. This would become an issue if you added another .040-.050 lobe lift or more. Just more info.

Hmm, all the rollers we run are over .600 at the valve or around .380+ lobe lift so that likely won't work.

Wouldn't it depend upon the base circle?

1994-03? 60° V6 lifter on base and full lift. Note this is with a Summit 2801 so the base circle is somewhat smaller.

Would a higher ratio rocker make up the difference? Of course, that doesn't help the affordability.
