What is the "perfect" street/strip package......for the average Moparian

It's the the maintenance due to being a stroker. It's the maintaining the tune with the carb with the cam that will support 550-600hp in a 4" stroke SB combo. It's more than time, it's the knowledge too. The stall will help though.

What takes this out of the average person is the costs involved to actually utilize the 550-600 horsepower on the street.

What was mentioned:

Caltracs

custom 904 built to take 550-600hp

double adjustable drag shocks

good 8" stall converter

good valvetrain to support cam lifts that provide 550-600hp

Dana rear end?

Driveshaft that supports 550-600hp

... the incidental supporting cast of parts have some expensive bills

Yes, for 11 years. Driven regularly.

It has nothing to do with the stroke.

Maintaining a 1.4hp/cu-in is different than 1hp/cu-in or less motor that's regularly driven on the street for the average Mopar owner.

Back when MP sold those 380hp crate motors.... most people had eyes bigger than the stomach and bought those instead of the 300hp. And sure enough year or two later customers come back asking about dual planes, EFI, other ways to detune them. This is from ns1rm21 that was a top seller of those at Westoaks MP.

Okay, which one is it? My first car was a 65 dart with an 273. The valves had to be adjusted on the 273 more often than either my 408 or 434. Plus the dealing with the points that seemed to burn up at least twice a year.

As I posted before I run the valves once a year on my 434, they’ve never been off more than .001” and that could easily be me. The cam is a solid roller, 263/271 a .050”, .711/.719” at the retainers after lash. Hell, it hasn’t had a timing light on it in years and I’d be willing to bet it’s still right.

Good parts cost the same for a 340 as they do for a stroker. I have the 727 that was behind my 340 and I wouldn’t hesitate to use it behind the 434. My 408 did break the 8 3/4 on the second pass it hooked up, 1.38 60’ was just more than it could take.

Anyone that can tune a 273 or a 318 can tune a stroker, it’s not rocket science.
