I completely understand your situation, I moved from Colorado to Georgia just about a year ago for similar reasons and am much happier here. I wouldn't rule out GA, less hazards for hurricane stuff and cost of living is very low. Just stay away from Atlanta, obviously. The Carolinas are nice...

Ok good, just making sure... I learned the hard way that the 'parts cannon' approach (wasted money). The fuel system mods you are doing are worthwhile even if there aren't any issues currently. Definitely sounds ignition-related at this point, I wouldn't rule out the MSD box being bad either...

Have you checked ignition timing yet? Alternators only put out as much as the electrical system demands. You can run a 200-amp unit but if your electrical accessories only pull 40 amps that's all it'll ever put out. What's the voltage when running? There is more diagnosis you should be...

The myth that Engine Masters debunked is that aluminum heads need more compression to make the same power/torque as iron heads which is untrue. Aluminum has much less tendency to have hot spots in the chamber. Heat transfer away from the chamber is too slow to matter but localized heat buildup...

Bullet train in Japan.

Shift kit, deep pan and aux cooler will go a long way towards making a stock 904 last. The one in my Duster is a bit of a mystery, rebuilt with supposedly some upgraded hard parts but the guy I bought it from circa 2010 didn't know much about the details. FWIW I put about 35k miles on it...

I'm excited for 440 day! ...oh wait

Thanks guys, I think I'm going to swap the carb first and go from there. I'll refer back to this thread if I still end up needing to upgrade my fuel system.

I'm pretty sure the "issue" is the carb, it's sensitive to float level and the bowls aren't very big. I've had it since 2016 and since moving from Colorado last year and having to pretty drastically richen it up for the change to sea-level air the fuel system can just barely keep up. I never...

I'd agree but this is mostly a street car and electric pumps that aren't mounted inside the fuel tank are noisy as hell. Ideally I'd run an in-tank pump and bypass the mech pump (and ditch this carb for a Holley DP) but for the time being I just want something I can add into the existing system...

I have a 750 cfm Street Demon carb on the ~450 HP 360 in my '70 Duster with a stock replacement Carter mechanical pump and stock 5/16" fuel line all the way from the tank pickup to the carb. Fuel supply seems marginal for my power level as after a second or 2 at WOT I can see my AFR slightly...

Hughes prides themselves on using "REAL CHRYSLER" fast-ramp cams (high lift for a given duration) which do give more performance but at the cost of valvetrain longevity (mainly springs and lifters). A buddy of mine used one of their hydraulic flat-tappet cams in the SBM in his Ramcharger truck...

Lots of factors involved... You mention running a 340, those tend to have less grunt than 360s. I'm wondering if you're getting into the power enrichment opening the throttle that much when it's in 4th, might be better off downshifting to 3rd when you need any extra acceleration. I know the...

Pile up some JB-Weld on the pan rails and main webs too, "DIY Race Block for cheap!"
