Recommendations for Build *specs inside*
Recommendations for Build *specs inside* This is what I am currently running, the only thing I am missing is the cam specs but I can tell you it is not very big at all. My plan is to run a high comp NA motor with spray. I feel like I have a solid platform and here is what I have
413 cid LS2 from Scoggin Dickey (EL TORO GRANDE)
• Cylinder Block: LS2 Aluminum, 6 Bolt main, 4.005” Bore
• Crankshaft: Eagle 4340 Forged Steel, 4.100” Stroke
• Connecting Rods: Scat 6.125”, 4340 Forged, H-Beam
• Pistons: Manley Dished Pistons, 8cc
• Piston Rings: Akerly & Childs Ductile Moly
• Camshaft: MTI “S1” custom cam for 400 cubic inch and up motors ( unknown specs)
• Timing set: HD Single Row
• Reluctor Wheel: 25x
• Fast 92 Intake Manifold
• Nick Williams 92 Throttle body
• Patriot Performance Heads
64cc stage 2 heads
650” Lift springs
Titanium Retainers
Super 7 Locks
21-4N Stainless steel High-Flo valves
2.02” Intake Valves
1.57” Exhaust Valves
5 Axis CNC Ported-Polished Heads
Harland Sharp Rocker Arms
NGK TR6 .35 Gap
AC Delco O2 sensors
• SLP Air lid and K&N air filter
• 180 Degree Thermostat
• Walbro 255L inline fuel pump
Exhaust:
• Corsa cat back exhaust
• QTP Electric cutout
• SLP equal length long tube headers
• Random Technology high flow catalytic converters
• SLP smooth high flow bellows
What I am looking for is 520-540whp NA and add a 200 shot. Currently make 502/486. I need suggestions like a better intake, bigger primaries on exhaust etc etc. I would like to keep what I have as far as heads and block and just rebuild/refresh but if you think my components are better on a different head I could be game for that. Just if you have some time please holler, thanks.

Definitely a fast 102 but the msd is probably a better choice. For headers at least 1 7/8" primaries if not 2 inch. I'd also go to dumps or an X pipe with dumps. If that's too loud (which it is really loud!) go with 3" duals out back.
I think you can keep your heads, cam, etc. and change those things and get the power level you want. It's definitely possible.

[QUOTE=Jtm2085;19769397]I agree with the intake and exhaust upgrades, but I think your heads are holding you back more than you think.[/QUOTE
I figured that but was not sure, would all those components move over to AFR or TF bare heads (springs, guides valves etc)

Heads are definitely the hold back. My buddie 402ci makes 545 rwhp with a 247/255 cam from Pat G. His 402ci features TEA TFS 235s out the box, 11.5 compression, a Mamo ported fast 102mm. His car run 10.4s with a 6 speed at 3750 lbs race weight.

Another quick question, will my assembled head accessories move to the TF heads?

he's using yella terra rockers. The lift on the cam is .632 on both the intake and the exhaust. Lsa is 111. Kooks 1 7/8 headers. At the time the car was built 2 inch headers wasn't on the market..
TF 245 or equivelant
2 inch primaries
102 intake MSD or Fast
Cam around or close
247/255 cam, 111 lsa, .632 on both the intake and the exhaust
I should mention Ill be going E85 because im hoping to be 12.5 comp for nitrous.

well that's good news, I was hoping to save a little bit by getting the bare heads. This may actually happen lol. so just recap
TF 245 or equivelant
2 inch primaries
102 intake MSD or Fast
Cam around or close
247/255 cam, 111 lsa, .632 on both the intake and the exhaust

I'm not yet educated on E85 so I can' help you with that part but it sure does sound good!!
Im thinking I’m going to go with the 245 mongoose AFR head, Pat G custom ground cam, 102 fast intake/tb and 2 inch primaries to 3.5 full exhaust out the back. That should put me at 540-550 hopefully then spray the crap outta of it lol

I would go Tfs heads myself due to the valve angle and more track proven results...
Mainly bc TFS245 require a 4.125 bore size while the AFR245 is 4.000 Min, they seem to flow almost the same air and are about the same price.
Before messing with head brands Whats up with that cam Is it a solid lifter. Where are you pistons @ tdc. In or out?

No cam specs, it’s a mild cam with not a lot of lope. This was all done prior to me owning it and that’s the one thing the previous owner did not have.
