New MOTOR!!
I went to replace the rear main seal that was leaking oil very badly. Bearings were worn so i pulled out the motor to replace them. Crank needed turned and the bores needed honed so long story short im getting a new short block and rebuilding and porting my heads.
it is a 1982 f150, 302. the new short block is from Ford Motorsport. it is a 302 short block with a roller cam.
now i bought a new flywheel since my trucks flywheel has the 28oz balance and this new short block has a 50oz balance. I also bought short pushrods to use with the roller cam and a new distributer gear for the same reason.
My question is with the firing order. is the firing order of this new short block drifferent from the motor that was originally in my truck? Will i have to change the plug wires around? Is there anything else I need to do differently to get this new short block in my truck?

Yes... The firing order is different. The order is the same as a 351W rather than earlier 302's. All you need to do is change the plug wires around. The other thing that will be different is the distributer gear. You will need to dump the one you have. I cant recall if you need a bronze or steel gear but I know it is different...
Your new block may not have smog ports in the back of the heads. you will need to drill and tap these ports if you wish to keep your smog intact... Otherwise ditch the smog...
