NEED HELP W/ NEW BUILD

88BlueGT · 01-11-2006, 04:48 PM

This is my first 351W build so I need some experienced people to help me. This is basically the setup. If there is anything that you would/wouldnt run please let me know. Any suggestions or comments are welcome! Thanks so much in advance for all the help.

418 Forged CNC Motor
10.5:1 Compression
Forged Steel Crank
4340 Full Floating Forged H-Beam Rods w/ ARP Bolts
4032 JE Forged Pistons (have an option between JE, Probe, or Manley... WHICH ONE?)
Promoly Ring Set w/ Special Low Tension Rings
CL-77 Rod and Main Bearings
CNC Ported Aluminum Avenger Cylinger heads (225's) or AFR225's?. WHICH ONE?
Pacific Performance Products Aluminum Roller Rocker Arms (keep?)
Manley Chromoly Pushrods
Pacific Performance Parts Custom Hydraulic Roller Camshaft (Im thinking around .580...)
Speed Pro Roller Lifters
Fel Pro Gaskets
Canton 7 QT Pan
Melling Oil Pump
Moly Oil Pump Drive
Main Studs
Pacific Performance Parts Main Stud Girdle with ARP Studs
Moly Head Bolds
Edelbrock Victor Jr Manifold
SFI Balancer
Polished Aluminum Valve Covers
Balanced and Completely Assembled

What cam size? I was thinking something in the .580 range...
What converter size? The car will be driven on the street 80% of the time. Its basically a "Sunday Driver". (I'm also running a Super Comp PA C4)

Is there anything in the setup that you see that you could replace with something that will work better? Thanks for all the help. I know its long.. sorry.

AFR225s are the sh*t. cam i would run mid to high 220s intake duration @ .050, mid to high 230s exhaust, lift in the middle 500s.

For those heads you are going to need a bigger cam then that. First though, is it a roller motor or no?
With those heads your going to lose low end but have huge mid to top end.
The good thing though is you have enough cubes to make up for the torque.
I would look for a cam in the 110 LSA area with about 232/238 dur @ .050" and roughly .570" to .600" lift. with 1.6 rockers.
I'm just estimating, but with flow of though heads you want to take advantage of it.
The duration i mention should keep it pretty streetable. It should keep you under 7000 rpm as well (barely)

Well, Ive been discussing it with people in the 5.0 sections and I think Im going to go with something right around .600. Also, I forgot to mention they are Avenger Pro "R"'s. They flow 320/235 and yes its a full roller. And yes I def want to keep it under 7,000. Maybe 6,500 if possible because like I said its going to be driven on the street atleast 80% of the time and I wont see that power too often so theres no point of having it if Im not going to use it. Any other suggestions....?
