*k.t.* · 11-01-2009, 07:39 AM

I have a 69 chevy C/10 long box and the motor sites more forward than any other truck I have seen. The shifter boot is even diferant. it has an angeled bottem on it. It is the origenal 4 speed and rear end. Does anybodys truck have this? Or can anybody tell me more about this?

need pictures of the mounts and what kind of engine

*k.t.* · 11-01-2009, 10:25 AM

I don't have a camra right now. It is a 350 with standerd small block mounts. On the frames that i have looked at the front motor mount brackets has 2 positions it can sit in. Mine is in the front 2 holes.There is about 6" of clearance between fire wall and the distributer cap.

6 cylinder and v8 mounts are different.
theirs a couple of places on the frame to bolt the mounts up to.
if you put the left mount on the right side.
so theirs about a dozen different motor mount positions you can come up with pretty quick with these trucks.

The motor mount brackets have factory rivets in them. It was a factory 350 and facrory 4 speed.and even the shifter boot and hole in the tunnal is factory. truck has been in family sance new and has never been modified.

2 wheel drive trucks had the engine moved considerably forward verses the 4X4 you are comparing it to.

71swb4x4 · 11-01-2009, 10:58 AM

If you are comparing it to your Blazer then it should sit further ahead. In the 4x4's the small block will sit very close to the firewall. As a matter of fact if you have HEI on a small block on a 4x4 the distributor cap may sit within 1/2" of the firewall. The 2wd's have the engine sitting forward a couple inches more. I believe the 4x4 is set farther back to give the oil pan more clearance between it and the front differential.

It depends on what you`re comparing to.The 4wd V8s sat back into the firewall.Also,many who swap V8s into 6 cyl trucks use the cyl mount locations so they don`t have to lengthen the driveshaft or move the crossmember.

Factory engine mounts were never riveted to the frame. Are you sure they're not 3/8 bolts ?

*k.t.* · 11-02-2009, 04:09 AM

I gess i have never looked at any other 2wd with factory V8. as for as the rivets on the motor mounts i must be mistaken. I have allways thought thay were rivited on. Never looked that close. thank you everyone for the info.

**special-K** · 11-02-2009, 06:26 AM

Well,there ya go.Now ya know.

Sure are alot of little things to notice about these things,huh?It never ends...

*k.t.* · 11-03-2009, 03:28 AM

does anybody know why the factory did this?

scott123 · 11-03-2009, 07:41 AM

Currently doing a 69 SWB 4WD, came factory with the 292 six cylinder, with a 3 speed manual and a Rockwell T-221. I switched to a 350/350/205 combo. Seemed simple til I tried switching mounts on the frame. Only one set of holes in the chassis. Only one set of holes for the trans. crossmember. Never saw a frame without multiple sets of holes. I had to get a crossmember out of a 72 K-5 bolt it to the engine and slide into place, drill new holes and bolt them down. My buddy said I had the only Chevrolet in the world that Chevrolet parts would not fit...LOL....scott

2 wheel drive had the motor positioned in an easy too service location that helped ballance the truck out (when fully loaded)
On a 4X4, as mentioned earlier, they did this due to needing the driveshaft for the front axle to be longer, so the engine had to move back.
