If you're going carbs, I'd do a custom tunnel ram fabricated manifold.

I havnt definitely decided to graft carby plate to the plennum and mentioned in an earlier post possibility of fabricating a manifold .
Fabricating a manifold would eliminate the necessity to plug and smooth the injector bosses but would creat some grief around what to do about the coolant tubes passing into the existing injecter manifolds.

An LT5 would look pretty good with 4 Weber DCOE 45s...
... make that DCOE 48s
It'd starve with the 45s, even if ya got it to run with carbs...

Looked into the MSD 6010 again today as a ls coil ignition swap option with crank nose reluctor and trigger .
Does anyone know the lt5 cam sensor trigger and reluctor setup ?
The msd requires a cam signal matching the stock ls1 triggering .
Anyone know if lt5 cam signals match ls1?
