J's69Mach1 17 Report post Posted September 30, 2009 I am trying to gather parts for my conversion from a 4 speed top loader to a T5 using the T5 bellhousing. I have a 69 mach 351w. My question is which flywheel do I need? 28 oz ?157 teeth? My harmonic balancer is a pioneer 28.2 oz imbalance. And I am assuming I will be using the 10 1/2" clutch set up for a 5.0.:helpsmilie:Thanks Jaime Quote Share this post Link to post Share on other sites
Horizon 10 Report post Posted September 30, 2009 I used a 52 oz....machinist said he could get a better balance with it. Since I hadn't purchased a flywheel or damper, it didn't really matter much to me. I figure balancing for 28 or 52 will take about the same amount of labor/shop time, it was a mute issue, especially since I was not buying from him anyway (he knew this going in), I don't think he had any reason to lie to me. More rotating mass of the 52oz MIGHT equal slightly less HP/Trq, but considering my combo, I'm going to have enough trouble planting it as it is. IMHO, whatever you might loose is negligible anyway, but I digress... Quote Share this post Link to post Share on other sites
Jayru 17 Report post Posted September 30, 2009 You need a 28 oz. flywheel (157 tooth) because your motor is balanced at 28 oz. The older 28 oz flywheels run a 10" clutch. You can find'em in 84 and earlier mustangs/F150s. The t5's out of the 85 and up 5.0's used a 50 oz. 157 tooth flywheels and run a 10.5" clutch. If you try to use a 50 oz. flywheel with a 28 oz balanced motor you will DESTROY the engine. The older 28 oz. flywheel is what you need with a 10" clutch. You can buy a fancy new 28 oz flywheel that will allow you to run the 10.5" clutch, but they run upwards of $300+ dollars. Quote Share this post Link to post Share on other sites
SlimeGold 69 15 Report post Posted September 30, 2009 (edited) Here is the flywheel I purchased when I did the T5 coversion in my car. Works great with a T5 bellhousing and a 69 model (28oz) 302 or will work fine with your 351W.http://cgi.ebay.com/ebaymotors/302-351-28-28OZ-STROKER-FORD-SFI-Billet-Flywheel-TMD_W0QQitemZ170387368327QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item27abe0e987&_trksid=p4506.c0.m245. It is a very nice flywheel for the price, it works perfect, and you can bolt on the diaphram style pressure plate and 10.5 inch 87-93 Mustang 5.0 clutch. Makes it real simple and can save you a few bucks if you don't need a real heavy duty clutch. Just go to a local parts store and buy a clutch kit for a 87 Mustang 5.0. If you do want a better clutch than a stock replacement, just pick one of the many available street/strip clutch kits for the same 87 up Stang. That's exactly what I plan to do when I get my 347 built. I'm getting a Centerforce kit and keeping the same flywheel.

J's69Mach1 17 Report post Posted October 1, 2009 Did you use a cable setup for your t5 set up? If so which brand? Quote Share this post Link to post Share on other sites
SlimeGold 69 15 Report post Posted October 1, 2009 (edited) Yes I used a cable and it was my own brand. I made all the coversion parts myself using a cable for a 79 Mustang. If you want to avoid messing with a new flywheel/clutch and making a cable work, just get one of the adapter plates that bolts a T5 to your toploader bell. Mine was a automatic before so I had to start from scratch. Edited October 1, 2009 by SlimeGold 69 Quote Share this post Link to post Share on other sites
Rodman 11 Report post Posted October 1, 2009 I have a 157 tooth 28 oz flywheel that came with my engine that I didn't use. It's part # FPH 30228 from RPM International. Here's their website: http://www.racingpartsmaximum.com/flywheels.html I also have a T5 bell housing if you're interested for $125 for both plus shipping, (or best offer). Thanks, Joe Quote Share this post Link to post Share on other sites
