Some one I know has a set of Erson roller rockers (1.6 ration) that have never beenon a car (New)and wants $450 for them. Is that reasonable? I know they do not make them anymore. I seem to remember them costing a good bit.

Certainly cheaper than the original price. Seems like I remember that the holddowns needed to be modified on those. If you do get them be sure to ck that out.

I think the shaft dia is smaller so you will need matching shafts also

I just recently got a set of erson W2 econo rockers, NIB for 5 bills, shafts and all ready to bolt on.

Are you refering to just a set of rockers or there very different then the norm shafts.

If its the complete kit...run with it.

These are the rockers on the shafts. Looks like you just neeed the hold downs.

Contact Robb Mc about them if I remember correctly he was involved in the development of those rockers. He will know what problem arose.

are those the standard shaft @ rocker's or the offset shaft @ rocker's for the w2/w5 race set that are for sale

I could use a few spare rockers for the w2/w5, anbody have 1.6's for sale?

If those are the rockers for a standard (stock) SB head, they sold for about $550 (the W2/W5 were about $750). I designed them and ran the very first set on my 340 Challenger with stock heads. With a flat tappet cam or hydraulic roller, they will run forever. They should be complete with shafts and spacers. If not, pass on them since you can't buy the special shafts anymore.

PS. Don't pull the rockers off the shafts if you don't have to. The early versions used roller bearings which were not caged and the needles will fall out. Reinstalling requires holding them in place with a little grease (assuming you didn't lose any when they fell out), and holding your tongue just right. I wanted to run caged bearings from the beginning but Erson had a ton of the other bearings they wanted to use up first.

These are for standard heads, no offset. I am not sure whether they are old or new versons, but it is good to know about the bearings. They are on the shaft with the spacers. I am only looking to run a Hydraulic cam and Edelbrock heads on a mainly street driven motor. Just was wandering if it was good price. Seems to not be to bad at a $100 less then they sold for.
