Thread: 70 challenger engine angle?

Tweet

Me and my buddy are working on his 70 challenger. It has a 440 in it. We pulled it out along with the automatic transmission and are putting in a Keisler 5 speed. All is going well, however I cannot find anything about what angle the engine sits at. Like idiots, we didn't check the engine angle before pulling it and that tranny out.

Any info would be helpful. Thanks.

Mike

Ideally, with the body at the attitude you want to use on the street, the carburetor mounting plate on the manifold would be level front to rear and side to side. This would normally put the motor on a 2*-3* down bubble to the rear because the manifold pad is machined with an angle to the front to facilitate this.

That's the same advice given to me for my ford 460, and it worked well!

Hey Tech; I'm curious what if you got a front sump pan and because the motor is tilted back the oil is going to the back instead of the front. Thanks Kurt

I don't know Kurt, I've wondered about that myself. I guess the sump is deep enough to keep oil around the pickup. The rear tilt is only about 3 degrees anyway and so whatever oil might slosh back there would run back to the front and down into the sump again. I'm just speculating here. It must work ok, because Ford has done it forever. I think I remember a baffle also at the top of the sump to prevent oil going to the back.

At this point, one of the Chevy guys is gonna say something like, hey, they're not fast enough to slosh oil to the back anyway.

eyeball the diminsion of where the trans bolts to the crossmember---what if any is the difference between the mount/center line of output shaft---do your best to duplicate this distance and the angle will be the same-

A rule of thumb in aviation is one degree course deviation equals one mile in 60 also works on engine angles---a one inch differance in rear mount height will be equal to one degree IF the distance from trans mount to engine mount is 60 inches---

Thanks for the replies guys.

Thanks Techinspector;
I've got a 8 qt. road rally pan with trap doors screen and the rest of the works,
so it is not a problem on mine. I was just thinking about it since I to am at the point
where my trany cross member is getting ready to get welded in. Thanks to 737pilots
question made me re-think my angle, along with your reply. Better to 2nd guess myself now, than after everything is welded in to place, thanks again guys Kurt.

Oh for the not fast enough remark I'll just disregard it.
See Bob Glidden won the world championship in 1973 with a de-stroked 351 cleveland.
The only reason he de-stroked it was he like to see the competition in the rearveiw mirror,
and he wanted to tease them. And thats what I am gonna do with my 351 Cleveland.
HE! HE! HE!

Man - O - Man I must have really scared them chevy guys with that Bob Glidden story.
HE! HE! HE! Kurt

It might have been destroked but I think it had been repaired by welding 8 sleeves into it( in a pizza oven, no less)

When people used to ask me why Bob was so fast----I'd look at them to make sure they were comfortable in their race track lounge chairs and then tell them it was because he spent more time under his car instead of a trackside picnic
