Car Forum / Antique and Collectibles / Studebaker / August 2005R3 Header Clearance Issue
Has anyone put a V8 with R3 cast iron headers in a 59 Lark and if you did, how did you resolve the major and I emphasize major clearance problems with header to steering box (Ross box)? Background before questions come in: engine mounts are in the correct holes for left hand drive, thick front motor mounts are used, new rear mount in correct holes in cross member. Ron I'm not sure about the Lark, but I know the headers absolutely would not fit on my '53 with the stock box. Switching to the "SL" (Ross?) box from a later Hawk fixed the problem. Maybe that could point you to a similar solution with your Lark?

Ron The Super Larks had a offset pitman arm and had a Z'ed link from the pitman arm to the pillow block arm on the center of the front crossmember. The clearance problems are caused by the pitman arm shaft's boss on the box and if I could clear it the next issue would be the top of the pitman arm. I'm talking about raising the engine 3/4" to 1" inch for everything to clear. Ain't gonna do that. Don't want to deal with getting pinion angle back in spec and related issues. >> Has anyone put a V8 with R3 cast iron headers in a 59 Lark and if you >> did, how did you resolve the major and I emphasize major clearance [quoted text clipped - 5 lines] > The Super Larks had a offset pitman arm and had a Z'ed link from the > pitman arm to the pillow block arm on the center of the front crossmember. > The clearance problems are caused by the pitman arm shaft's boss on > the box and if I could clear it the next issue would be the top of the > pitman arm.

Raising the engine 3/4 " to a 1" is not going to change the angle on the back of the trans more than 1/4 to 1/2 a degree I would be more worried about clearance of the hood but on a Lark you have all kinds of room. The old mounts have probibly compressed more than a 1/4" in their life. And when I was looking at my car I could see a slight difference in the height of shaft to the 3 mounting holes on the frame but was just thinking that was because one was power and the other wasn't. New front and rear mounts. >> The clearance problems are caused by the pitman arm shaft's boss on >> the box and if I could clear it the next issue would be the top of the [quoted text clipped - 9 lines] > of shaft to the 3 mounting holes on the frame but was just thinking that > was because one was power and the other wasn't. |
