Updating Carbs

[spdbrake]

I switched to a couple Moroso 8.5" air cleaners.


My Aeroflows I got from AU have about 30 miles on them if you're interested.

This is awesome. Just a few questions.
1. Would like to know where Spdbrake got your alternator and serpentine setup. Also curious about the PCV system.
2. Wondering which jets and rods you ended up with.
I'm almost done with assembly on my 408w and 351w long blocks. Found a new engine shop after the guy that built my shortblocks went out of biz.(don't get me started) just need alternators, starters, and pulleys. Then it's off to the dyno hopefully by the end of this month. The 351 is 10.3:1, 235/239 cam, and a pair of Holley 450's on a Price manifold. But the 408 is 10.7:1, 244/250 cam, and the 1903/1904 setup on a air gap. I would really like to go in with the Edelbrock setup close, as this new(to me) dyno guy claims to be a holley expert, but clueless with Edelbrocks.

The Edelbrock's are super easy to tune and don't require removal of the carb to re-jet, change rods etc,,,
Carb tuning guide here: https://edelbrock-instructions-v1.s3...ning-guide.pdf
See pages 33&34 for the 1903/1904 carbs.
Read the tuning guide I posted a few responses up. It is detailed.
Since you'll be at at Dyno shop you will need to bring Two #1940 tuning kits (2 carbs) which has an assortment of rods,springs, jets.

Me telling you my jet/rod size on my 408 is not useful for your 351, cams/heads/intakes/displacement all different. I feel I'd be wasting your time.

Alternator: I use a Bosch 3G 95Amp AL75522N I like the angled support better as it keep the alternator lower on the head plus the clocking of the wiring connections are low and outboard right side of the alternator out of view.

Pulleys: I use the March Performance Hi-flow kit. #1675. Just more gpm for traffic and my engine does not live at high rpm.

These are clockwise pulley sets.
Ensure your timing cover and water pump are both clockwise.

You can run a CCW pump and timing cover, the water pump pulley will be smooth and not ribbed.

Alternator bracket: March Performance, #30055. There are several companies making clones of this setup.

I modified my turnbuckle rod length to tuck the alternator closer to the intake radiator hose.

PCV breathers: I got bored so ditched my screened breather for a catch can. There's never anything in it and my rings are tight so no blowby.
