Best Top 10 Bolt Ons For a 318

Cam (I like what "used to be" called an "RV" cam) AKA somewhere between a stock 360-2bbl cam-COMP 260-stock 340 regrind or so
Double roller timing set (Ive taken a liking to the Edelbrock "true roller")
4 bbl intake and carb (stay away from Holley) and resultant needed air cleaner to fit the 4 bbl
Lean Burn Ectomy if it applies
either a set of "302" or "714" heads mildly ported, mostly clean up the leftover bad casting remnants.... the current 302s I have are worst in the oil drainback area (yeah I know that area doesnt help performance.... but if it prevents me from laying my fingers open while setting them on/ in place, it helps MY performance)
or even a set of uncracked Magnum or EQ heads with needed altered length pushrods and Magnum-derived rocker gear
DRIVE THE HELL out of IT!!!!! !

The last 318 I did was a HUGE noticeable improvement over stock, was in a D250 that I used as the truck it was!!!!
My son just "bought back" that D250 from my cousin, and that same 318 is going into his C body wagon at least temporarily...... and he WILL beat on it.....
