Thanks guys........not that I don't mind the shaking, but just the engine shaking independent a lot from the chassis.

Running a fairly radical 408 with lots of cam in 71 Dart. Currently have regular engine mounts with torque strap. Problem is the engine shakes around a lot and the header clearance is very, very tight. Shiny new ceramic TTI's, and I don't want to chew them up. I have a set of Moroso solid mounts...

Ramcharger...what kind of issue, if any, am I going to have with sealing on the head gaskets with those high CR's. I plan on using the good bolts\studs??

I am considering building a 408 to run on E85. Could not find too much on this forum, unless I searched wrong. Would like to go with 12 to 1 on the compression??? The engine will have forged crank and H beams, aluminum heads flowing in the 300 cfm range. I have read lots on the fuel system...

ace26, Nice looking Duster! What does it weigh to do the 12.4? Thanks.....

Thanks Moper.....!

Moper, Where do I find directions\instructions on opening up the main oil passage? Thanks...

Thanks for the suggestion Moper....couple of questions?? What should I have checked on the eddy heads...they will be new? Chamber size? You said replace the springs......so the springs which come with the new heads will not be sufficient, correct? Thanks.

Good advise! Will go one better one the "Sparky Thing".

jimmyray, whose rockers and push rods are you using??

Thanks Jimmyray, you are correct the engine did have rollers in it. Maybe in the future I will go back to one. It was in a truck and I was suprised to see it came with a windage tray.

Here Here.....agree with you on all points

Thanks rumblefish360......any HP or ET estimates for the combo, I'm thinking high 11's and 475??

Not that I would not like to have the roller, but thee money.....and thee little Redhead I am married to. I am trying to do the best with the budget I haves. Thanks.......

AdamR, I was sortof pondering 235-240 @.050 with around .530-.550 solid. I understand the flat mechanical will give me a little faster opening. Vacuum not a problem no pb.

Could live with either, no roller however More Strip though.......

Thanks AdamR, Have not picked a cam yet, wanting to get some suggestions. I had planned on getting the Milodon, but not ordered yet. Headers not purchased, but would like to go with the TTI's. Thanks.......!!

Greetings to all...first Post! I have spent a couple hundred hours reading all the words of wisdom in this forum. Would like to get your comments and suggestions for picking a cam and estimated et and hp for my 408. 71 Dart, all steel cept for cowl hood, battery and cell in back, cast crank...
