I'm tearing down an old 350 and turning into a high hp 383 (425-450hp) and I'd like some opinions on the parts I'm leaning towards getting. It will be going into what I plan to be a street legal (barely) racer


-Eagle or Scat 4340 forged crankshaft (3.75" stroke)
-Eagle or Scat 6" 4340 forged connecting rods (btw, which r better, I or H beams rods)
-JE or SRP pistons
-Holley Street Avenger 770CFM carb
-Holley SysteMAX Kit (claims 425 hp/425 ft-lbs on a 350 on the dyno)which includes, intake manifold (idle-6500rpm), Lunati camshaft (Intake .473"/290° @ .006", 105° centerline; Exhaust .488"/297° @ .006", 115° centerline), and aluminium heads (intake runner 215cc, exhaust runner 68cc, 66cc combustion chamber)
-if I don't get the SysteMAX kit, I'll probably run a slighlty more aggressive cam from Comp Cams, Edelbrock Performer RPM Airgap intake manifold and either Dart Pro1 or Holley heads

Any and all opinions are appreciated

 

i'd run more cam and i'd run a lunati. i like i beam rods, look at the weight and consider the lighter, also look for rods that use a bolt instead of the bolt and nut and i'd go 6" rods. big part of the equation is what do you want this engine ot do for you.

 

I would run a roller cam with more lift, say .535 & about the same duration & Holley 750cfm, Edelbrock single plane. H beams are little stronger than I beam & will give good clearance on stroker engines. I beams with bolts threaded from the bottom up will work too, for clearance.
