I wish they had this system for the SWB K10 4WD. I'd be all over it.

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Sure would be nice if the instructions:
https://documents.holley.com/199r11655.pdf Listed the part number for the spacers for the different transmissions. It was by dumb luck that I discovered the 11/16 spacer for the 4L60 is PN 71223012HKR. I figured they might be included with the crossmember. But, for $30+ I'll be machining my own spacer. |

Hey Todd I asked these questions in post 71
----------- I have a question about which Holley pan will be even with or above the engine crossmember? 302-2 or 302-3 ... what would be the main differences in the pans? I also notice the recommended bolt kit for the engine mounts 71223015HKR says they are 150mm long and the recommended bolts according to the instructions are 140mm long. which is correct? --------------- I think I have figured out the pans, but what gives with the 10mm difference in bolt length? |

I see that it was briefly touched on, but will the mounts and transmission crossmember work on a '64 shortbed? I understand maybe the header and exhaust layout might be different. If unsure - would it be possible that I purchase the mounts and crossmember and if it doesn't work return for a refund? |

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
The two other part numbers for the transmission crossmembers for this application were released today. As I mentioned in my answer to post #82 above, the main crossmember assembly is the same in all three crossmembers, the two new ones added today just come pre-packaged with specific spacer blocks that are used to accomodate the transmissions they are listed for use with.

Hey Todd,
Just a little product feedback. I got my BHS511 motor mounts and 71222024HKR Crossmember today. Everything fits great. The only thing strange is the bolts provided for the motor mounts have a very small head. I'm not using them anyway but they are definitely not appropriate for the job. I do appreciate the flange nut and bolt, but the flange on the 3/8-16 x 1 bolts is too small. http://67-72chevytrucks.com/gallery/...lley-bolts.jpg |

Thought I would update with some pictures of my test fitting. This is a stock 5.3 as pulled from a 2003 suburban with the truck oil pan and stock AC brackets. I thought it was interesting that the pan and ac compressor fit. I'm not using the factory AC brackets but the main part was still on the motor so I thought I would throw the compressor on to look. You would have to cut out part of the frame for the lines to be able to hook up as I have seen others using the low factory bracket have done.

I only had to cut it on the drivers side. http://67-72chevytrucks.com/gallery/...nchor-3064.jpg |
Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Jason - can you post a picture of the pan in relation to the crossmember?
I'm interested how low, if at all, it hangs below the crossmember. |

I'm kicking myself because I knew someone would ask this. I didn't take any pictures of it and took the engine out right after I took these pictures. It hung down 2 to 2 1/2 inches below the crossmember. It had plenty of clearance everywhere else on the crossmember. |

Re: Hooker Blackheart 1967-72 C10 Truck LS/LT Swap System Info Thread
Toddoky,
Can I ask why you kept your oil pan 1.5 inches off the front cross member? The reason I ask this question because when I was running a T56 magnum to keep the engine angle to a minimum I had to trim the upper trailing cross member pass thru hole to clear the drive shaft. Seems to me the engine could be lower maybe an inch? I am running 6" drop in the back. On my 68 C10 LS I'm running a F-body oil pan. With just using my calibrated eye ball (and a tape measure) the drag link is a bit higher than the top of the cross member. Not saying your engineers haven't done their home work just asking. |

Ahhh I hope my ctsv pan will clear the front crossmember and center link. Should have my parts next week.

Our son and I are working on a '72 C10 Fleetside that we've completely redone virtually all of the front end on, Wilwood disc brake conversion, RideTech StreetGrip install, and new steering set-up incl. a new Borgeson steering box. Next up will be a new exhaust system once we get a few wiring items straightened out.
Our present set up is a 1st gen 350 w/TH350. Has a carb w/headers. Exhaust comes out directly in front of the rear wheels. Gas tank has been relocated to the rear. Previous owners put Cherry Bomb Extreme's on. The drone is excessive and wears on us after 10 minutes or so. Our eventual goal is a daily driver. An exhaust system is next up for us. Just found the Blackheart system and we're very interested & looks like this could very well be a potential option for us. Since we have a 1st gen SBC w/headers, we are uncertain if this set up would be compatible with what we have. We are interested in the Borla S-Type exhaust as well, due to presumably having "no drone". We'd prefer to have the exhaust come out the back, but be nearly hidden, perhaps just seeing the tips below the rear bumper. Do these mufflers have any drone? How do they compare to the Borla S-Type? Are you able to purchase this system, if it could work with our 1st gen set-up, without the mufflers that come with it? Two pics included which are from when we originally purchased the truck in October. Appreciate any input you all might have! Ryan D. Orlando, FL |
