89 305/350 TPI swap

Hi all,

I'm planning on buying a 305 TPI TA this weekend. I've gathered alot of info so far for the 350 swap. I'm going to use higher compression pistons, a medium cam, and port the heads. I've removed and overhauled stock engines before just never swapped anything with fuel injection. Please correct me if I'm wrong on anything.

Buy a 87-89 camaro/TA 350 so it uses MAF and the intake bolts line up.
Replace with 22lb injectors and 350 PROM.
Replace motor mounts.

Questions:
1) I cannot find an aftermarket PROM for 350 TPI manual (because they did not exist), which should I use?

2) Do I need to upgrade the fuel lines and fuel pump?

3) What years of 350 heads will be compatible with my intake?


Thanks.

1) Use an aftermarket chip.

2) No.

3) '87-up iron. Stay away from LO5 heads.
