Frame Side Engine Mounts
I have seen few different questions about this topic. Here are some pictures of the FACTORY style mounts.
The dirty black ones are factory small block mounts in a 1965 C-10. These came out of a 66 C-10, and are shown mounted in the correct holes for the factory 283/327 from those years. The blue ones shown sitting next to them are the factory 6 cyl frame mounts for the 230/250 from 64-66. Those mount in the rear holes on the upper frame rail. Notice on the cross member the hole that is painted black around it. That is the lower hole for the 6 cyl mount. These are lower on the crossmember than the forward hole for the V8 mounts. ![]() ![]() ![]() I hope this helps someone when looking at the Factory style mounts. Note that the Factory BIG BLOCK frame mounts were only on the 68-72 model trucks. They will work on the 63-66 trucks. I am not sure which set of holes is correct for the BBC mounts. I just know from these that I have are the factory locations. My truck was an original 6 cyl that I got from my grandfather. The small block mounts came out of an original V8 truck from a wrecking yard in Stonewall, TX.

Re: Frame Side Engine Mounts
I wonder if it made a difference which trans the truck had. If I recall, the V8 truck I pulled mine from was an automatic (Powerglide I believe)??

Re: Frame Side Engine Mounts
The 292 6 had the right mount forward and the left mount in the rear. My 66 had a 6 with the mounts in the rear holes.

Re: Frame Side Engine Mounts
No wonder I see so many questions about this. Seems like it was not given as to were the factory mounted the engine.
Anyway, I will be using the black mounts in my photo's and mount my SB in the front holes. I will post pics when I get the engine in the truck.

Re: Frame Side Engine Mounts
6 cyl (230-250) to the frt holes sbc to the rear holes original. in almost 50 years a lot of things get mickey moused by people not knowing what they are doing. if you are using the std bellhousing(or the cast iron p/g-60-62) you are to have a problem lining up the bolts for the frt mounts.
If you are using a rear trans mount(unless orig equipped) you can put those frt mount wherever that you want then just adj that rear trans mount crossmember where it is going to line up. the next person who may own that vehicle may have trouble understanding it if they go to modify something. or they may wonder whu it is always running hot as the fan sits to far forward in the shroud, but you wouldn't tell them that ron Last edited by padresag; 02-22-2010 at 02:46 PM. |

Re: Frame Side Engine Mounts
Not so...My truck was an orginal 230 6 cylinder/3 on the tree. The frame mounts were in the rear holes. My grandfather had this truck until he gave it to me when I turned 16. It was all original except for the seat cover at that time. I ran the 6 until I sold the engine about 8 years ago. Never moved the frame mounts. That is why the frame has a rusted spot where the original mount was (the blue one in the pictures above). When I did that frame paint, I never removed the mounts, just blasted and painted them along with the rest of the frame.

there is a 2 1/2 " difference between being mounted forwards or backwards look at it this way. Standard bellhousing no matter what eng after 62 is the same and all mount to that crossmember that runs underneath of it the same way. factory installation for a 230-250 were in the frt position. 283 was located in the rear position. if you put either eng in the others location with the bellhousing in it's std location how are those engs going to bolt up to the perches. doesn't make sense does it. ron |

Re: Frame Side Engine Mounts
Uh fellas, do you realize that those frame stands that mount into the front holes are easy to find? Look in any 67-72 small block truck. There they are. Exact same part.
And the frame stands for rear holes, look in any 250 inline 6 67-72 truck. Again, same part. I'd bet I have powdercoated over 50 sets of them in the last year. I buy them at swap meets, refurbish them, and send them to a new owner.

Re: Frame Side Engine Mounts
"You don't have to move a small block forward from the factory location to be able to run tall valve covers or an HEI."
I couldn't run tall valve covers on my SB in rear holes, pulled the dist( HEI) couple times though, no probs. Karl your welcome to my check my mounts against yours, because I'm not sure of original motor, it definitely had the front crossmember. ![]()

Re: Frame Side Engine Mounts
I've not had any problems in the past with running tall valve covers on a small block in the original rear position. But I suppose it depends on just how tall of covers you are trying to use.

Re: Frame Side Engine Mounts
Get a set of 68-71 big block frame stands. They are easy to find over on the 67-72 section of the parts board. Expect to pay about 75 to 100 dollars for them.
They will mount in the front set of holes in your frame and crossmember.

Re: Frame Side Engine Mounts
glad i searched & found this...another member who lives in my area had pointed out that my engine mounts were in the 6 cyl. location (rear holes)....i have a 327 that was installed by the PO...the original was a 283...so, i was about to ask what all geometry it would throw off by moving to the front holes, thinking mine were in the wrong spot...now i really don't see any reason to move...but i like for things to be how they're supposed to be...so, i guess i can just leave them alone

Re: Frame Side Engine Mounts
Very good info here, I'm currently in the process of installing a 327 in my '64. Due to the shifter location of the trans going in (MY6) I'd like to use the forward set of motor mount holes. Less cutting into the floor.
Is it possible to use the inline 6 perches/towers and mount the V8 in the forward holes? We tried it and it turned into a wrestling match that we didn't win. I see there might be different perches depending if it's a l6 or V8. Maybe I need to track some down for the V8? Thanks |

Re: Frame Side Engine Mounts
Okay wrestling match is poor description. We initially dropped it in the rear holes and it bolted up great. Slid the perches forward and couldn't get the motor mounts bolted to the perches.
I'm assuming this is because the frame narrows towards the front. Not sure. Just wondering if this has been done? Aggie91, do you know if the black perches from the original post are from a power glide? I'm thinking that is what dictated the factory using the front or rear bolt holes. And maybe if the front bolt holes were used, the perches were different.? |

Re: Frame Side Engine Mounts
After some digging around the site, it looks like some 67-72 perches will allow use of the forward holes.

Re: Frame Side Engine Mounts
You must use the '67-'72 engine mount brackets for a small block. Those are designed to bolt in, in the forward location.
In the '63-'66 trucks, ALL 230/250, 292, 283 and 327's were installed in the rear location from the factory. The only engine mount that was different is the passenger side of the 292.

Re: Frame Side Engine Mounts
Thanks John, it now looks like I'm gonna need to move the shifter ahead a few inches regardless, so may just leave the engine in the rear holes.

Re: Frame Side Engine Mounts
Dracko,
Just saw your question. I do not know for sure what trans the truck had that I got those mounts from. I ended up not finishing that conversion back in 2010. I hope to get it back in the shop this year to get it in driving condition, maybe with a LS swap...
