Starter Recommendations?

I just got done with a Holley Sniper TBI installation and am having cranking issues that were not there before. The only real current draw change is a Holley electric fuel pump that appears to be a power sucking pig. So now if my radiator fans are running, I can't crank the engine over enough to start it. A booster pack placed at the battery fixes the issue immediately so I don't believe it to be the solenoid or ignition switch. I have an Optima Red Top 1000CCA battery that I was sure was the issue but it load tested fine. I have also checked the suspect SPF main chassis ground and it is also fine. I measure voltage as low as 9V while cranking throughout the car which seems low (solenoid, main 12V distribution points, etc).

I'm thinking whatever starter Roush out on the 427R c2006 is maybe not the best choice and may have aged badly but I' m not expert on SBF starters.

Any thoughts on a high torque starter that might have a lower current draw while cranking the engine?

Update:

I put in a Powermaster 9603...great starter. But the problem was the Optima battery that had load tested fine. What a POS. I popped in an Interstate MTP-34 and I could now drive it down the block using only the starter motor!

Summit sells one.
What size is your cable from the battery to the starter?
I recommend #2 awg welding lead (fine strand wire) that will carry a lot of amps.

here is another source
I have bought several and they are good starters. Don't let the price scare you.

First things first.
Make sure all your connections are extremely clean and no corrosion, then retighten very well. Also, make sure you have a good ground to the engine and the starter. If you can, run a good ground wire from the battery to the starter.
The biggest cause of starter problems is corrosion or other interference with a good connection at the starter and/or solenoid, and an insufficient ground. Once you have that absolutely determined to be good, then look at starter problems since it looks like your battery is good.

Thanks for the tips. Wire gauge should be fine, solenoid is in good condition.

Giving this more thought...As it’s happening when hot, it could also be heat soak effecting the starter.

Maybe the ticket is a gear reduction starter as what I’m after is solid cranking with the least amount of current draw. The 427R is only 10.5-1 with a moderate cam so it shouldn’t be too demanding.

I installed a mini starter on my 393 with 10.5 compression and haven't had any problems with it.

You might need to run a ground wire from the engine to the battery and make sure it is the same gauge as the positive lead. The newer electronic components especially fuel injection units need this to operate correctly, a ground to the frame is not sufficient. What will happen is they will look for ground through all the other wires, this could potentially burn out other components in the vehicle. If this is not the problem try an MSD Dyna Force starter.

This had crossed my mind but as I updated above, it was the battery. It was starting great all afternoon yesterday as we set the timing.
