Random thought,, Dont know what kind of under hood room you've got, But I would run ITG foam filter(s) on that injection and get rid of the screens, we played with a sprint motor with Kindler injection and the screens were a huge restriction at 6500 and up. Plus they don't really stop as much as I like.. But I'm one of those folks that seems to be cursed with if it can eff up it will.. LOL

The ITG got us like 15HP over the screens.. And it helps smooth the air flow over the stacks so they pull better.. (According to our engine guy.. ) We also tried a big box K&N but the cleaning was a pain in the rear.. Ran good but took me like 2 hours a night to clean even with an outer cover..

Default Timing Chail = 1/2" Pitch

Hi John, good to here from you.

One item, little known, is the Avon Gear timing set I sell.

This SBC "single" chain set has a 1/2" pitch for strength.
Billet steel gears with a thrust washer is also part of the set.

I like Crower Cams products as I get BELOW WD pricing, a discount that I can pass to you ?

I sell Smith Brothers push rods at a great price.
