just wanting to know want to expect
91-tbi to 91 sd tpi
i will be having a Lt-1 cam installed at the same time
maybe 081 ported heads
and I'm also installing a 3.23 open rear converted to pbr disc
also adding the dual cat system
and flowmaster cat back

if my car runs high 16s now what should i expect to run after

i just want to know if its all gonna be worth it
or would my stock tbi heads work better with lt-1 cam and tpi

I'm getting the cam for 30 and heads would be 75 if he still has them

I'm really just looking for opinions and ideas
this is a budget build so please no high dollar ideas
getting the full tpi swap was hard on the wallet already
Ive already got 2500 in the car already mainly minor things and repairs

or what mod is going to give me the best bang tpi swap? better rear?

or just cam and heads
for the most part the rear and tpi swap is all being done the same day

and also am i going in the right direction for beating stock and mildly modded mustang 5.0s? really thats the goal

thanks
