Just making sure these fit Lt1's-- don't always trust website assurances ;-)

Getting a new cam and heads from LE, and he recommended 30lb injectors.

Likewise, Comp Cam #1418-16 (Magnum Roller Tip Rockers Arm Sbc 1.6 3/8 Rocker Self Aligning)-- good for LT1?

Congrats, working with Lloyd. Friendly, knowledgeable.
I talked with Lloyd. purchased his largest custom grind billet cam. Fantastic results.

You talked with Lloyd. Knows his products for sure.
Factory ported LT1 heads stage 1 vs 2 ?
Trick Flow LE1 vs LE2 ?
Cam 212 vs 218 ?
30 - 32lbs injectors will support 400hp
Summit link. to trick flow 89030 Inj correct EV1/ 14.4 impedance.
Way over priced. Better deals out there.
Delphi Injectors. Or. modern Bosch III
CC 1418 not worth it. same ball as original.
slots can hit the rocker studs bigger grinds.
LT4 uses. proven Crane gold full RR.

LE2 heads with a custom grind cam similar to a CC503. He advised the Trick Flow, but they do seem pricey-- I'll look at Bocsh and Delphi (would those be OEM but larger?).
Talked with Lloyd yesterday and he said full RR's as well.

Thanks for the advice!

Delphi, makes most parts. GM Labels as. AC Delco.
Can purchase any lbs increment. Close to your new HP

Bosch III modern efficient standard. Can purchase any increment.

Lukas, another quality brand.

Great deals can be found. Especially, non popular lbs.

Make sure you buy injectors with good data/specs available for V offset and flow/ pressure, and provide to the ECM tuner… note that it’s common to find knockoff injectors on Amazon or eBay so if it’s too good to be true, it probably is. Check coil resistance to specs.
