Mystical Heat Shield... elusive flex plate

[Scruffy]

Ok, I let the questions build up and now have some doozies.


1) What is the difference between a flywheel and a flexplate?


2) What is a heat shield, where is it located on the intake manifold and do I really need it to install an Edelbrock 4bbl w/EGR intake manifold? If it's that sheetmetal contraption on the bottom of the old intake manifold, how can I reuse it since it is riveted to the old manifold? If it's to help prevent vapor lock, will the 2" Holley carb spacer I am planning to put on my Edelbrock 4bbl performer carb fill in for that role?


3) With the timing cover replacement project complete, I really want to finally get this thing running. I noticed the new aluminum intake manifold sits much lower in the lifter valley than the cast iron manifold did. Will I have enough room to close the hood after installing the 2" spacer between the new intake and carb if I utilize the Edelbrock "low profile" reusable air filter (featured on page 115 of the latest SummitRacing catalog) ?

The Jeep is an '82 with 360AMC V8.
Thanks in advance for the help

flywheel is for manual tranny...flexplate is for auto tranny

It is the shield that is on the bottom of the intake. You can remove it by drilling out the rivets. Why would you want to use the 2" spacer in the first place?? I have used the performer intake and carb on a 360 in the past and think you will see a noticable difference from stock 4bbl and definately diff than stock 2bbl.

The air cleaner you are talking about is the lil triangle foam type?? In my opinion they are not very good cleaners. Had one on my 83 CJ7 with the 360 and performer package and removed it after about a week. Get a good aftermarket cleaner with a paper filter. Seems to work alot better.

Plus if you ever backfire thru the intake you will catch the foam on fire. Been there and done that! Then you have a huge mess to clean up.

Ah, that helps a bunch. I had psuedo-mechanics at work trying to tell me the flex plate was attached to the flywheel (sounds awful twisted to me). Thanks for the info.

The reasoning behind the spacer is feedback from a friend that installed a 1" spacer on his 305 Ch*vy small block. He cannot stop raving about the performance increase. Then shortly after I read an article in an off-road type magazine that had mostly positive comments to make about spacers in general. They indicate the (open-bore) spacer allots more time for the fuel and air to mix, allowing for a more ideal "mixture".

I've already bought the thing, so I figure why not use it. It certainly can't hurt (unless I can't close the hood http://www.ifsja.org/ubb/frown.gif ). If this turns out to be the case, I will rush the 3" body lift project I had sitting on the side.

The Edelbrock air filter is indeed that bug-eye looking triangular contraption. I haven't ordered it yet, but if you all say it does hardly anything well but melt upon backfire, I think maybe I'll pass after all.
Thanks for the info!

plus the spacer will do nothing for your low end torque flex plate attached to the flywheel thats a good one right up there with muffler bearings ...lol
