396 LE3 heads/intake/cam
im going to start building my 396 stroker. im definately going to go with the LE3 setup, sounds about the best. Im thinking about putting a blower on down the road(not 100% sure yet). Im wondering if the LE3 setup would be blower friendly or not. What would u guys/gals reccomend for pistons/ rods/ crank? ans also if there is anybody running a similar setup i would like toknow how it worked out for ya? also what kind of power do u thinki can make with an N/A setup if i decided not to go blower? Any ifo on this stuff is greatly appreciated. i want to get started on this a s soon as possible.
Thanks
Thanks

my advice would be to go to victoryracingengines.com
They have a really nice 396 short block for (i think) 4800. U can check what parts they run, or but the block, or even see if they would sellu a rotating assembly

i know a really good machinistat at home here so i dont really want to buy a whole shortblock. im just going to piece it together piece by piece i think. i can get some really good prices. but i will definately check out their rotating assemblies. thanks for the info

There are various options for crankshaft, connecting rods and pistons. You could go with a Eagle 4340 Forged Crankshaft, Eagle H-Beam Connecting Rods and SRP Pistons. We also carry the Compstar Speed Packs which consist of Compstar Forged Crankshaft, Compstar Connecting Rods and Mahle Pistons. Or we carry a variety of parts that can be put together into a custom kit.

The issue that you will have from the blower to the NA setup is the compression and the camshaft.
A NA cam vs. a Blower cam are completely different, so expect this when you change. A comprimise cam wouldn't work well in either setup.
Same with the compression. You are looking at 12:1 in the NA setup and 9:1 in the blower setup. Both would need different pistons. The -14cc SRP dish pistons wouldn't be good for the NA because they would be way off on compression and the blower can overpower them since they are a NA design.

i understand all that but im on the fence if its going to be blown or not. lets just say its just going to be a nasty N/A motor then what kinda parts we talking. it still needs to be pump gas friendly though.

i think i would like to run a little less compression just to be on the safe side and to not have to worry about tunning the car every time the weather changes though.

Just have the chambers in the heads be a little bit bigger then. TFS heads can be about 64cc and with flat tops that will put the compression in a safe spot on a 396. I just did a 396 that was completely safe at 11.8:1 and it had 62cc TFS heads.

FYI.....The 13.3 compression was a pure accident. We there thinking the car was running 12.7 to 1 and found out we put a thinner .029 gasket on thinking it was a .039. Stuff happens!!
