      So got the spacers and going to try them tomorrow. .hopefully they fit and i can tq the heads and check the measurement of the push rods..

      Also got the intercooler plates milled and they are at the machine shop to have the spacer waterjetted out..the new cooler is double thick at 1.50" and uses 1/2"npt fittings with 3/4" lines..it has many other features that make it far superior to the old one..the zzp cooler was .75" and used 3/8" lines..

      I need to wrap the headers and get the alternator and power steering brackets mounted and measure for the 8 rib belt..then i plan to drop the motor and trans in,all goes as planned should be in but not running by Sunday .

      The intercooler spacer will be done wed so hopefully get the supercharger on and everything buttoned up next weekend..

      I have a dyno tune adjust appointment on September 22 at 2:30 ,should give me time to break the motor in and work out any bugs..

      I just got my elite back so get ready for picture overload

      You made my night, I am going to dream about racing tonight. lol
      That intercooler looks like it will work way better by the size increase.
      Good luck on the rest of the build!!!!!

      Lol thanks.

      Yes its going to flow twice as good,the old 3/8" lines were really restricting my pump..everyone keeps saying im wasting my time considering im running ethanol and my temps wernt to crazy..But adding 8 more pounds of boost and spinning that m90 to max is going to create alot of heat and i dont care if the motor can handle it..the cooler the air the better!!

      Your not far away from me,some day we may meet on the track..lol

      Out of curiosity, what intercooler pump are you running?
      Those head gaskets look cool!
      Are you feeling better about the rocker assembly now? It looks good.

      Still runnimg the bosch pump.
      I just hope they hold in the compression and dont leak..lol

      Honestly not much..the pushrod guide on the end of each assembly is slightly off causing the roller tip not to stay centered on the valve tip.i may pull the plates off and weld one side of the guide and mill it so the pushrod holds the roller centered..its not far off so haven't decided if i want to be that ****..

      .also manley sent me lash caps for the top of the valve tips as when the cut the valves down outa the cores they hade, they cut below the hardening of the tip,so technically mine dont have hardened tips which is why they suggested valve tip lash caps..this adds height to the valve tip which may effect pushrod length. .at the time i wasnt going to run roller rockers,ive called them back and they said i dont honestly need the caps with roller rockers but i feel much better running them,they also give a little more surface area for the roller to ride on..

      I do feel better about the spacers i had made and the bolt changes made.he also stoppeded water jetting his name and "4.0" into the plates..ill post pictures of the caps,spacers and the rollers that arn't centered tomorrow before i check pushrod length. .

      so the cooler sandwiches between the two plates? or is there something else that goes in there. i always thought you had to have it sealed inside the intake or it would leak boost

      Yes it sandwiches between the two or it did,im cutting a "spacer" to take up the gap it has now..basically cutting another hollow plate,all 3 will sandwich together and be sealed

      Here are the two rollers that are not centered,they are not far off but im just being picky 20170826_132106.jpg 20170826_132000.jpg

      And here is the lash caps and the difference if i was not to use them..

      The rocker roller tip pulls inward as it pushes the valve down. The arc.
      are the rollers centered looking 90 degrees from the above pics? ( sideways)

      Well got a slight problem ..the locks are different from intake to exhaust, one uses a single groove and one uses a tripple groove..its like this on all 4.0,the valve is same length and install is all the same..just one lock is thicker..

      Well the caps depth is .090 which it fits fine on the exhaust valve tip but the intake it doesnt fit flush ontop the valve tip,it hits the lock..so when the valve goes to open it pushes down on the locks,not the valve tip..so lash caps are out...

      No this ""should"" be it
      https://m.summitracing.com/parts/ctf-df490309

      The disc itself fits the splines on the trans and also fits in the flywheel..the pressure plate doesnt fit the flywheel..its "slightly "" to big and the bolt patterns are totally different. .

      Im using the fidanza flywheel 186401
      https://m.summitracing.com/parts/fiz-186401

      And the trans is a modified T5 from a 06 Mustang 4.0 sohc

      Well I definitely have the wrong clutch. Just went to Advance Auto and a 06 Mustang definitely fits my flywheel... I have no clue what Clutch is this. I guess I will have to call the tech line tomorrow and see if they can identify it. Would be nice if I could just get a new pressure plate considering the whole clutch cost $600
