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.
