1973 340, want more power.

Here's my 2 cents worth. This engine was built over 30 years ago when my father was still the original owner before I bought the car. Std bore 340 with factory 10.5 pistols. Stock x heads with port matching and milled to bump compression. Cam is a Ramcharger solid lifter 500" lift, 300 duration, although these days there are much better choices but it does sound VERY wicked and is streetable with the 4 speed. H.v oil pump and Carter street fuel pump. Milodon 8 at oil pan and Heddman husler hedders. 40 yr old Holley 780 carb that STILL works great. Stock valve covers hide the 273 adjustable rockers and still has the stock air cleaner. Molar electonic ignition. Nothing exotic or highbuck. With 4.56 gear and dragradials, bone stock suspension with pinion snubber, this 3200 lb dart drives to the strip, runs 12.20s with mufflers all day, then drives home, after a stop for ice cream.lol. Forgot to add it has an oldWeiand Xterminator intake. This motor is shited at 7000rpm, although it's missed a few gears and seen the north side of 7500. Point is, in a a body with a 4 speed or a GOOD converter, DONT skimp on the converter! A decent set of gears and tires, itdoesnt take a stroker kit, alluminu heaads, or exotic pieces to build a 340 to go deep in the 12s and still live a long trouble free life!
