300WHP Supernatural 3.XX Coming Soon! (Page 23/54) pmbrunelle AUG 22, 11:59 AM I did not see that video yet. At 6:10 in the video, we see that your heads are very different than ordinary Fiero heads. On the stock car, the intake port is much smaller, and it is hard to see the valve. In this video, we see a lot more of the intake valve stem. I know that Glyptal 1201 is a common choice to help the oil flow and return to the oil pan, and the Glyptal 1201 does not degrade and end up in the oil pan, clogging the suction screen. I suppose the Dupli-Color with ceramic is a paint you have experience with, and it works just like the Glyptal? La fiera AUG 22, 02:46 PM quote Originally posted by Will: It's very red. Are you concerned about engine oil degrading the paint on the areas that will be inside the engine? Going for a Quaife for F23? Got your 4.40 FD from a Saturn Vue yet? I have the same paint type but in black in the 3.4 that's in the car and the paint is holding very good. I'm used this type of paint in all my builds and never have seen paint chips in the oil filter. As fat as the trans, yes, I broke my piggy bank and order me a real diff. (I took your advice) I kept the same 3.94 F23 because it fits this combo very good. The 4.40 is still in my wish list. lou_dias AUG 22, 04:39 PM quote Originally posted by La fiera: Yes Patrick, they are CNC machined so all the intake and exhaust are exactly the same respectively. As the paint it is just Dupli-Color engine paing with Ceramic. Key is to have the surfaces free of grease or oil and mask the places where you don't want painted. This is how I did it. https://youtu.be/Oxfhyvdj7ZI Man - after watching that video I almost wish I just bought heads off you. Mines should be done soon. Hand-ported. Only 1.25" diameter exhaust ports however I'm having the bottom of the ported enlarged to the D shape.

La fiera SEP 04, 04:38 PM I came home to a surprise on the mail! It's a long weekend so, yep I'll get up early tomorrow and start tearing the engine and trans out. pmbrunelle SEP 04, 08:45 PM Do you have the shim selector kit for this transmission?

I don't know what you mean by that!!!??? pmbrunelle SEP 04, 09:29 PM The differential is supported by tapered roller bearings, squeezed between both sides of the case, correct? You need just the right amount of preload; not too tight to burn up the bearings, but without any looseness. At the factory I believe that they used shims (of different thicknesses) to get just the right preload, even though the parts have variation. A shim would have been placed between the bearing cup and one side of the case. If you're changing the stock differential for this one, and possibly installing new bearings, then it's likely that the preload could change. It should be checked.

I leave this work to the best. I have a gentleman that all he does is NASCAR race rear ends and differentials. He asks me what is the application, HP and type of racing and he does the rest. I concentrate my efforts on engine building and driving the car, he does the rest. The same with my machinist, I design the parts and do the math and he does the rest. When you delegate your work load becomes more managable. Even thouth you think you have everything under control, something is slipping under the rug. pmbrunelle SEP 04, 10:22 PM Ok that's good. Actually setting up a differential in a transverse transmission is very simple compared to setting up a differential with right-angled gears, so it should be a walk in the park for your guy.
