It's not a pull method for everybody, but it worked well for me. I've got a thread on it if you hadn't seen it. Initially I had some kickback from the board for thinking outside the box, but once I brought pics, people started to get it. Quote Selected
88 sport rebuild , need advice Reply #91 – July 14, 2013, 09:46:40 AM jcassity,Sounds like you have a good plan!I ran a set of Total Seal gapless rings when my dad and I rebuilt the original 302 in the Bird back in the late 80's. That motor was pulled from the car and sold to a buddy and by the time they finally retired his mom's 85 Cougar it had over 200K on the rebuild & never used oil. The thing you definitely do not want to do is run gapless rings with a power adder. You can do a Google search on that and it is well dospoogeented.Darren Quote Selected

88 sport rebuild , need advice Reply #95 – July 14, 2013, 12:20:52 PM Tom,Thanks for the catch! I should have been a bit more clear on what I was saying.Tom made comment on questioning how the top ring on the piston controlled oil usage. I should have clarified that what I was saying about the design of the gapless ring not using any oil was just a thumbs up to the Total Seal ring package as far as longevity was concerned. We also had the heads serviced with new guides and a valve job so I am sure that contributed to the longevity as well.jcassity,I also forgot to mention that your concern with the aluminum roller rockers is something you need not have. I have the Crane Energizer roller rockers on my Coupe and they have had zero issues and I bought them used. I am pretty sure that Ford would not have used the Crane aluminum roller rockers in the 93-95 Cobras is there was going to be a longevity issue. Again, the biggest thing is to upgrade the valve springs like so many here have said.Darren Quote Selected

I have FRPP 1.6 roller rockers on my Thunderbird (made by Crane, they are not the Cobra ones but the blue 1.6 ratio) and they are beefy pieces. If you are going to buy roller rockers stick with name brands (FRPP, Crane, Comp) as they make quality aluminum roller rockers. DO NOT use the cheap, less than $200, aluminum roller rockers from eBay/China. There is a reason they are half the price of the quality ones. Quote Selected

88 sport rebuild , need advice Reply #102 – July 15, 2013, 10:15:37 AM that sounds about right. you have to remember that you have 1.6:1 rocker arms. The actual lobe lift will be less, .444 lift is at the valve. Measured lobe lift x 1.6 should be in the neighborhood of .444. Quote Selected
