Long-off 340 build

As far as price concerns here, let's assume the price factor is negligible

I didn't know there was an OD 833, I'd only heard of the 3-spd and 4-spd then the Passon conversion that fixes the 4-spd's awkward gear ratios. LS-300 mentioned Passon's 855 so I'm gonna see if I can dig up more on that

A couple of the parts I listed were just in case if the stock ones were pretty well gacked and worn. Who knows with the state of how a lot of these cars are kept. i.e. if the radiator is fine then I'll keep it. However I do plan on a full brake system swap, I know it's a lot of work but I've seen some hairy situations with old brake systems bringing up some "surprises". I'd just prefer to do a total brake system swap. Speaking of brakes, Slopar72 was talking about hydroboost. Is this what he meant? > Hydro-Boost Power Assist Systems: Operation Diagnosis and Repair Safe and accurate assumption on power steering, so I'd look forward to a thread on that

So the TBI prefers a single plane, according to you and other sources including Engine Masters https://www.youtube.com/watch?v=2sQJPZYSoUI the dual-plane seems to complicate proper delivery to all cylinders with the EFI for some reason. To be fair, their assessment of the EFI system was based on their own trial and error. If the EFI can match those numbers then I guess a single plane it is. Is it me or there more dual-plane intakes on jegs? Mostly dual-plane and crosswind, only found a dedicated single on summit > https://www.summitracing.com/parts/dcc-4529408/overview/

Assuming there's a viable solution in place for brakes, I can be more liberal (gotta be careful with that word these days) with the cam. For starters, what size were the polyglas tires on the Demon? I figure I'd stay close to that size. That tire size and 3.55:1 gear ratio on the 8.75" rear. The gear ratios on that Passon A-855 are: 1st - 2.64:1; 2nd - 1.92:1; 3rd - 1.40:1; 4th - 1.00:1; 5th - 0.70:1........they also say it withstands up to a constant 700ft-lb torque, but the 340 would be well within that range.
