I have heard that there was two different size fuel injectors between the 305 and 350 TPI's. Is this true? If so, what size came on the 350's?

Thanks, Ben

 

LB9's (305) - 19lb/hr

L98's (350) - 22lb/hr

 

If you change your 305 for a 350, you can add 3-5 psi of fuel pressure and use your 305 injectors. But, the 305 injectors are only good for about 350 hp, the 350 injectors are good for about 440 hp. So, if it is an "extreme" 350, you may need to consider an upgrade.

Have fun.

 

Or you can get the Ford ones that are 24 pph ones, and run stock pressure if you have a MAF. That or get the EPROM redone.
