its a 408 tsp shortblock with -4cc flat top pistons,lg G6X3 cam,victor jr carbed intake,850 quick fuel carb,1 7/8 headers...the motor will have around 10.5 compression and i'm wondering if this sounds like a good power maker to ya'll...only thing i dont like is compression is alittle low for me and i dont much about the prc cnc'd l92's,and i dont know anything about the cam or its specs...this will be in a 2700 fox with a powerglide and a 8inch 4500 converter...any advice will be appreciated..thanks billy

Is it already assembled? If not, I'd consider milling the heads to get more compression, along with running a thin gasket!

If it helps my 408 has ported ls3's and 10.8-1 comp. I have a cam pat g speced for me designed for a 300 shot. My car has a th350 with 3.73's and a pi 3800 converter. Race weight is 3530 and my car is a dog out of the hole on motor. It went 10.70 at 126 NA on 93 pump gas. with a 4500 converter my car would be quit a bit faster on motor. That 408 sounds pretty good. Worst case you my need to play with the cam to get what you want.
Your car would be nasty with a good running 408

I had ported l92 heads and my car went 10.85 127mph on a 1.44 60 foot. I switched to trickflow 235 and went 10.63 130mph on a 1.56 60 foot. My 60 foots got worse due to worn slicks but i still went faster. Also,i gained 20hp and 15 tq more under the curve. With new slicks the trick flow combo could of went low 10.50's. or a hi-10.4. n/a on 93 oct,m6 car at 3,700lbs with me in it.
