Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
I installed the Holley Black hearts mounts with a stock C10 trans crossmember and Speed Engineering headers. All fit well, driver side 1/8” grind on the bracket but didn’t need to. Stock truck pans fits fine just a little rub on the steering shaft and below crossmember, if you’re not lowering the truck you’ll be ok. I can shim the brackets up 1/8” to 3/16 and it’ll be fine. But I’ll probably switch to CTSV oil pan because I have it. The bolts that came with the brackets don’t even cover the brackets well. Heard someone here they now provide some diffrent mount bolts.
