What E.T with this set up?

['82 steppin]

I got '82 stepside shortbed GMC truck and I got this 383ci laying around for some time and a friend of mine which is a drag racer told me bring me your engine and I will rebuild it for you and give you a set up that will blow your mind so I did and lucky me I found a set of brand new AFR 210(1054) heads that I bought for cheap with 1.6 gold rocker arms for less than 1000$ so I went to my friend and told him give me the part numbers or what parts should I order and here is the list of everything I got

383 roller block 6" rods internal balance
Aftermarket balancer and flexplate 0 weight
Milodon diamond windage tray
Moroso oil pan aluminum
Moroso oil pump (175$)
Edelbrock victor jr intake manifold
750cfm holley street HP
Full msd ignition and might swap the blaster coil to HVC blue
Battery relocation in the cabin
TH350 with 3600 holeshot B&M
1995 Impala SS rear end
Trick flow 246/254 .555"/.555" lift (on 1.5 and im using 1.6 so the lift is .592") on 112lsa
Hooker long tube headers super competition 1 3/4"
AFR heads 210cc intake port,2.08/1.60 valves,65cc chamber 80cc exhaust port
Aeromotive fuel pump,fuel regulator and fuel filter
22gal. Fuel cell
All braided hoses

Im sure im missing some other parts so what e.t in 1/4 you think I can hit with this set up? The truck already got Centerline pro convo wheels all around 15x8 front and 15x10 rear and was thinking of going 15x12 on rear

What compression ratio are you shooting for? Any tricks with pistons (small ring package, light weight, etc...) will also find you some HP.

Not familiar with the Trick Flow cam you posted as to which lobe profile they use (aggressive?). A custom cam taylored to the AFR heads and intake used might find you a few more ponies. I hope you are at least using a roller cam? I'd prefer solid for an all out HP attempt.

Need to run this thing on the dyno, and weight of the truck, along with suspension/driveline setup to really give you a good estimate on ET.

Sounds like a good start though.

This engine if done right should net you about 500hp and up with those heads. You may want to check the cam and double check everything else. I know there are cams out there that will produce as much power while being drivable on the street

What's your gearing? I imagine with 373 gears and stick rubber mid 11 sec 1/4 mile times will easy to get. Make sure you have Caltracs or a four link for planting the tires and keep the tailgate up

The gears right now 3.08 the stock one but I will change that to 3.73 after engine swap,the cam was tested on 383ci on fox body with lousy trick flow heads and it did 10.7s if my truck will hit high 11s I will be happy with that maybe spray it and get it deeper,now anout the traction I saw the Caltracs but I think I will go with 4 links or ladder bar

Ok I might get Caltracs instead of four links or ladder bar but do they offer for leaf above axle?
