actually neither, sure im gonna catch shit for this, but it is a 305,comp 274h cam,vintage edelbrock single plane(strip master) and lt1 cast iron manifolds... 454 tbi was necessary because of cam choice, engine does not start making power until almost 3200 rpm,but pulls stronger the faster its pushed...... with the 350 tbi it was choking at higher rpms.
That sounds like fun. Good reason to do things out of the stock box. It should pull enough air to handle 7000 and with upped fuel pressure it should supply enough fuel for 400+ hp. Keep us up to date on how it goes.

i havent had much time to work on the car lately, i did double check the wiring again, matches $0E for a 95 c/k3500 according to alldata...... tried a new iac just for kicks... no change...i can run the pintle all the way out (diagnostic reset) and leave it unplugged, car idles nicely. plug it back in, second start up it idles right back up... no datalog as of yet, cant get tunerpro to connect. im blaming win 10, will try to put together a win7 machine this weekend. my old mt2500 brick talks to it just fine.....
Slight update, idle problem is solved! ended up being a loose connection at the pcm connector, replaced the end in the connector, idles great now. also have datalogging now, bad obd1 cable on my autoprom, for now i just wired in an obd2 connector next to the obd1 and am using the obd1.5 cable for my caprice, works well, though i am having some trouble emulating and datalogging at the same time, keep having to flip the outside switch back and forth to get connection to log...have always had that problem though on any car i have hooked it to.... and i have to take the dash back apart because i still am not getting a speed signal, thanks guys!
