SpadzSaleen 10 Report post Posted August 8, 2010 Alright guys i have another problem with this motor that i am building. I need to know what size flywheel to go with and clutch. Ill give a little history on the car and the motor. Its a 1970 Ford Mustang Mach 1, i purchased with no motor originally an automatic car. Im converting it to manual with a 4 speed toploader. The motor is a 351w out of a 1983 Truck i believe. Bascially im just using the block. Im going to have forged internals, proform carb. Aluminum heads. The car is going to be a weekend cruiser with a bit of power. Now the question i have is what size flywheel should i go with?? 164 tooth or 157 tooth? Obviously if i go with the 164 tooth i could probably go with an 11" clutch? I just need some advice on what route to go with. Thanks. Quote Share this post Link to post Share on other sites

SpadzSaleen 10 Report post Posted August 8, 2010 Stupid question, if i went with a bigger flywheel the bellhousing has to be bigger right? Im very new sorry for the dumb question. If so will it mate to the 1983 block? I already had a bellhousing that had a casting number of D1TA which is supposedly for a 351 out of a truck (i looked it up) and it was way too big! almost an inch wider.
