This looks like a reasonable possibility.
Hopefully it would idle below 1K RPM?
I will message the seller.

That should idle smooth as silk at 600 rpm !
206/210 duration @ .050 lift
That is a stock replacement cam and the springs you have will be fine
 
So, roller retrofit kit from Comp runs a minimum of $1,100.00 :eek:
For a truck I really do not want to keep once I run a couple more errands with it.
Going piece-meal using suggested parts from this thread brings it down to "Only" $700.00 :unsure:
I have more than that into failed flat-tappets, so it seems roller is my only option. ack2.gif
As for the politicians who created this problem. icon_hang.gif
 
Have not pulled the engine apart yet.
Shop is FULL with other projects .
Have to finish something to make room.
Hope to get the MG running for 25 MPG and stop using the truck as my DD.
 
How do you figure $700 ?
The cam was about $100, lifters $230 and pushrods $60.
You don't need springs,
That's $500, about the same as a flat tappet.
I'm "assuming" the guy with the cam will come down from $150, but if not it's still a good deal.
Hope to hear that it's running good soon !
