Winter Project
I've finally decided on my engine buildup. I've got some questions and was hoping to get some feed back. I'm gonna fuel inject my 327. Here's what I have so far.
1968 327 c.i.d
large journal
bored .030 over
crank grind .010
TRW Hypereutectic Pistons
hi-performance connecting rods
chrome-moly pushrods
news rings, seals, bearings, freeze plugs
Cam shaft 220/231*@ 0.050, 468/480 lift, 110* separation
Double Roller Timing Set
Hi-perf oil pump & drive shaft
Now I want to fuel inject this engine;
Is the cam I have good or should I use something different?
Which heads are good to use S/R Torquers, Sportsman II or something from Trickflow ?
For the intake should I use a TBI intake or go with a single or double plane with an adapter?
The TBI unit, should I stay stock and put 350 injectors, use a 454 TBI or should I just put on a Mini ram/super ram/stealth ram setup?
How about the fuel pump and the AFPR?
An aftermarket waterpump or use the stock short water pump, will the stock pump work, I'll need new pulleys.
I'm going to get a new chip done.
I'm new to fuel injection and computer cars, so I just want some feedback, anything that I forgot or suggestions from you guys will help.
Thanks

You may have fun getting that cam tuned into a fuel injected engine. It can be done just not easily. The 110 lobe separation is designed more for a carb application. You really need one with at least 112 degrees of lobe separation.
Heads: Choose the aftermarket head that has the runner size and flow numbers to support the powerband and hp output that you are wanting to make. Larger cc runners build power in the higher rpm area. Small cc runners build low end torque. So choose one that is going to match the power band of the cam. A great head with a mismatched cam is worse than a good decent head with a matched cam.
You will also want the intake to match the heads as well. Lots of good carb intakes out there that can be used with an adapter for TBI.
I would say that you may need the 454 injectors to go with that 454 TBI or 350's with a lot of pressure.
