How about this 360 LA combo?

PowerWagon896 said
Okay, I have decided to forgo the de-stroked 360 idea & just go W/a streetable 10.5:1 360 for my sons "65" Valiant.

This is to be a moderate budget streetable daily driver to run on 93 octane pump gas. It will see ocasional strip use & I want it to terrorize The new Mustang GTs. I want to keep the engine work within $5000.

The car will be a sleeper & will maintain a stock appearance similar to this.




Here is the combo I have in mind. Let's say it would be coupled W/ about a 2500 RPM stall, Torqueflite W/3.91 axle ratio 8 3/4" diff.

I would start out W/a 360 LA block/rods/crank. Line bore the mains, square up the deck & take it to 0.00" W/the KB pistons. Recondition the rods W/ARP rod bolts & free floating wrist pins. The bore & crank would be cleaned up to OEM clearances.

  • Edelbrock Performer RPM heads, 63cc chambers/171cc int runners/77cc ex runners 2.02/1.60 valves
  • Summit Street/Strip Phase III Dual plane Intake manifold. (similar to Edelbrock Performer RPM Air Gap)
  • KB 107040 Hypereutectic flat top pistons @ 0.00" deck, .0015" clearance.
  • .050 " copper head gasket
  • Edelbrock "Thunder" 800 CFM AVS carb.
  • Dougs Full length ceramic coated headers.

What would be a good flat tappet cam for this set up? I am thinking Comp 480H. Can I run 1.6 rockers on the LA? I want to twist 6200 RPM out of it W/mid range torque & drivability being foremost.

Would this combo make a drivable 450 HP @ the crank?

Opinions please?
What quench clearance are you going to have? .035 or .065?
Youdo not need copper head gaskets - the Felpro will work or a better choice with dissimilar metals is the Cometics.
Why settle for a cam off the shelf - contact Racer Brown or Straightline performance. Bullet Cams have a lot more selection too.
Fro the price difference on a new build - go Diamond or Probe or any number of other forged pistons for the build.
For that light car up the TC to a 3-3200stall and a 650 mighty demon carb will make a very happy combo. 3.91sg w/7 1/2"B-B x 15" steelies and 255 x 60s will fit for the street.
Have fun :thumbup:
