Time to start spending money

[Pirate]

You never told me that...

I used (at Scott's recommendation) BBK 15110 (the coated 1511's), on my car, and was very pleased with the quality and fit. I went with the coated because I wanted them to look okay down the road. Also, make sure you buy some better gaskets (the ones included are garbage), and possibly some better hardware.

Are you running a Performer RPM intake manifold? I was making a recommendation for the RPM, not the basic Performer, however, the open spacer can't hurt any on the basic performer, if you have the hood clearance.

Nah, not the performer. I have the EGR spacer in place anyway, so I'm not sure whether I have the clearance or not. The intake is pretty low rise, so there may be room.

Funny reason to drop the coin on coated headers ... I the main advantage is their greater resistance to bleeding heat off into the engine compartment, instead keeping it in the exhaust gas itself to keep up the velocity and promote scavenging.

+50 on upgrading to Mr. Gasket Copperseal exhaust gaskets. Those things rock!

I agree on the gaskets....I just installed a set, and now my sex life is 800% better!

Alright I took your advice on the headers and carb spacer. Now I'm having problems getting the right flywheel/clutch for this thing. The fella at the parts store got me a 28oz balance flywheel out of a 85 f-150 and a clutch from a 90 stang. The problem is the fact that the pressure plate bolt holes are about a half inch off all around(too small). If I get a clutch made for the f-150 will it work with the '90 t-5 (spline count/fit in the bell housing)?

You are going to need to get the Mustang 28-ounce flywheel, as if memory serves me correctly, the installed height of the truck pressure plate is different....the Mustang clutch (1987-up, I think) is a 10.5" clutch, with the truck being an 11"...I would just measure the diapragm finger depth of both the Mustang and Truck pressure plates to verify.

All the Mustang ones the parts store looked up were 50 oz. Any other ideas out there or maybe part numbers that would be awesome.

[Grand Marquis GT]

Try a 1979 Mustang. The earlier 302 ones that weren't HO would work.

[1987cp]

Wasn't it '81 or so that they switched to the new-style crank that uses the 50 ounce imbalance?

I notice Summit lists a variety of diamaters in the flywheel section .... wonder if that could help if scaring up a replacement part doesn't work out ....

[Pesty351]

Nobody in town seems to show any part numbers for a 79-81 mustang flywheel. Why is this so hard to get a stupid flywheel.

Dorman #04392

Pioneer #FW163

Or, the INEXPENSIVE option!

Standard Flywheels #172

These are all off the partsamerica.com site. Might have to get it ordered, but there it is

Tom, this flywheel uses a 10" clutch, instead of a 10.5" unit like the 1987-up 5.0 Mustangs....and there aren't too many aftermarket replacements that are going to hold up behind a 351W...

Here's the only aftermarket unit I could locate...

One other note? You might be able to run a stock Mustang 50-ounce down to a local engine machine shop, and have the flywheel weight cut down to a 28-ounce bob...

[Grand Marquis GT]

I'd go with the unit Pirate just suggested.

Now thats an idea.
