Crower Lifters

http://store.summitracing.com/partde...5&autoview=sku

Looking at buying a set of these to convert to roller lifters. Whats the skinny on them? Are they decent. I noticed that they are 1/2 the price of crane and comp brand. I dont want to waste money on them if they are junk though.

Also, I am getting a set of GT40 heads with roller rockers on them. If i get these lifters, and install the heads, can i use my old pushrods, or should i get some new ones? I dont think the heads have guideplates on them. Is it going to be the right lenght though?

I don't think Crower makes a bad part. He's highly respected in the drag world. He costom cuts some of the best cams made so I'm sure they are good.
The pushrods would be a crap shoot. I'd try them but not hold my hopes up.

Retrofit

Stock pushrods won't work with the retrofit lifters. The lifters are taller. I suggest investing in a checking pushrod, so your preload is correct. Guideplates are recommended for roller lifters, that also requires hardened pushrods. Depending on your lift and spring pressures, you may also need screw-in studs. A "spider" or "dog bones" are require to retrofit roller lifters, because the lifter bores are shorter in the older engines.
On edit: What I said about the guideplates is for the roller lifters AND roller rockers.-Pete

So can i use guideplates with pedestal mount rockers? or do i have to get them machined with studs? I"m going to be using a stock cobra cam, with stock cobra heads. They have the crane roller rockers on them. The only thing i need to figure out is the pushrods and the lifters. I didnt think you had to use the dogbone with the lifters w/link bars? So its a good idea to get me a pushrod length checker. How do those work exactly? I'm still learning here, so bear with me.

The crane pedestal mount roller rockers are kind of unique. You don't need guide plates with them. They work like regular pedstal rockers. I run them too.
The tie-bar lifters don't need the spider that the stock ones need.
The pushrod checker works like a regular one that is threaded and can be locked down. You put it in and lock down the rod where you think you need it. Check the top of the valve stem until the rocker is rolling over center of the stem. I use a Sharpie to mark the stem and roll to over a couple of times to see the pattern.

I see. Then once you obtain the correct pattern on the end of the valve stem you take the checker out, measure it, and then purchase 16 that size. Do you need hardened pushrods with the crane roller rockers then? Is there anything else i'll need then? I know i need a bronze dizzy gear for the roller cam. I allready have a dizzy gear i pulled off of a 92 f150, that one should work right? It looks like its a different material than my non roller cam one. Thanks alot for the help, its appreciated.

Yup that's it.When you call summit for the rods they can talk you through the measurement they want. You can even send the checker to them. Check them all just in case. If the price is close get the hardened rods.
Your putting in a steel cam right? Get a steel gear. The bronze ones don't last long. You can either get new distributor or swap in a new steel gear.They usually need to be pressed on. Your call.
