Bored one night surfing E-bay for good deals when....
I saw a RV grind camshaft (

[email protected]/.442(ex) ) from General Dynamics for $25.00... new. Hmmmm.... bought it and stabbed it in my '85 LA 318 4BBl. Nice improvement and sounds really nice. Even has a lope with the unported, small valved '302 heads; I can almost lay rubber with my 2.45 open rear.

I came across a set of Magnum heads from a 2002 Durango. Hmmm... $200 for a complete set....okay... I bought em and slightly ported them and put 'em on my fore mentioned LA 318. Also a nice improvement. Still can't light up the tires at will but with a power brake, I get a good launch.

I came across a set of 1 5/8" Headman headers, new for $50 if you use the "Buy it now" button. Hmmm... so I "bought it then", installed them with a set of (2" in/out)header glass packs(Cherry Bombs) that bolt directly to the collectors...bought the glass packs... ready for it... on E-bay, $20.00 each.
The car is definitely louder and pulls a bit harder, but still...can't light the tires at will. Getting a little annoyed...

An E-bayer is selling his new Professional Products Air Gap Aluminium intake for the LA/Magnum engine. Hmmmm... $140, sounds like a deal. Week later I installed it along with a 600 cfm Holley Vacuum 4BBL. The car is not as efficient when it comes to gas mileage as it was with the previous Rochester QJet(new intake only accepts square bore carbs), but it does look much nicer... but still can't light the tires at will, almost, but not quite...

I came across a forged stroker crank for a 318/340(P4529710) with a 3.51" swing. This makes a .030 318 a 342....Even though the crank is a 8 bolt flange, for $300...hmmm...bought it!
Now that I have most of the components for a nice street machine, I can, with the proper cam and compression get my 3800 lb w/ driver Magnum headed(slightly ported) 342" Mopar with headers down the track in the low 13's.
Yes, there is a question here. Since this really isn't a 340 due to the unique stroke(3.51" vs 3.31") and the rod ratio has changed(for the better I understand) and I will be using Magnum heads with the fore mentioned intake manifold and carb, how would you build the rest of the engine to achieve the goal of low 13's in the 1/4 with a 3.55 geared porker(3800 lbs).
