Long-off 340 build

I know that it said "Stroker" which means stroked out small block, but the fact of the matter is that it takes it out to big block proportions. You're still tacking on more engine. I don't plan on stroking out this small block.

If going the hydraulic roller route you will need to inspect the lifter bores on your LA and see if they are chamfered or not. Depending on what you find you will need to either bush the bores or, an easier way, use the Hughes rollers that have the lowered oil band.
Hughes Engines

With regards to the 408 comment, I believe chrispy was referring to a stroked out 360. Also I think Blueprint uses Magnum blocks (LA based and a small block).
I listed below that that I'd need all the other upper engine bits (rockershaft, rockers, pushrods, lifters, etc). Comp cams also lists lifters which I believe are retrofit to fit in place of the stock tappet lifters COMP Cams: Retro-Fit Hydraulic Roller Lifters; Chrysler Small Block 273-360 but it looks like your pick was cheaper

The rear tire arent gonna do you any good at 225 60 15.lol
Then what tire size WILL work? I was looking at this 1971 Dodge Dart Demon 340 2-Door Coupe 4-speed tire sizes (since September 1970 for North America U.S.)

Don't get those headers. I would opt for some TTI short-tube block huggers or something else. I have those hookers on my motor and the driver's side is a PAIN to work on. I have to unbolt the header just to get the the #5 and #7 spark plugs
Good to know. Do you know where I can find ones like that?

IMO, being been there and done that with a lot of those parts, I would not do the single plane MPFI with that combo.

The listed engine above, the 408 IS a small block.
Not a big block.
The problem is dual plane hasn't been shown to play nice with efi, I know that's always been throttle body efi, but where else is there a bunged-out LA dual-plane intake? The only other port-injection-ready intake even remotely mopar was for a 440, and even that was single plane. Even if I were to get a dual-plane intake and weld in injector bungs, there are few standalone MPI systems minus intake. This set having everything at the ready is the least work for the money

No matter what, my options for efi-compatibility leave me at single-plane intake
