Chevy Vega 5.3
Vega owners...........Im considering a 5.3 swap for a motorless 72 I just picked up.
Anyone know if the stock exhaust manifolds will fit without interference?
Thanks for any help

Truck manifolds? Don't know, I have only seen pic's of them, they almost look like they might fit (or not). Just try it out and see.
The early stamped F-body manifolds will work if you cut off that large triangle flange and use a smaller flange. I have the later cast F-body manifolds, but those damned large flanges are in the way. I suppose F-body shorty headers may fit, but I guess they do not flow any better then the manifolds. So I do not know what to do.
Probably the best forum for Vega info is at H-body.org

Thanks for the responces. That would be great if the shorty's would work.
Im just looking to do a cam and exhaust for a nice daily driver.
Any Vega owners out there know for sure?

I thought the truck manifolds would pretty much only fit trucks cuz they go back before they go down. The F body ones go down then point back a bit. Truck ones go for cheap usually I think. I was gonna try the truck ones in my 87 442 with a 4.8 but I had to use F body ones, there is NO way without completely hacking the car that the truck ones would have worked.

Anyone have a complete small block chevy and a 5.3 to compare the overall width of exhaust mani's bolted up?
I had a vega wagon years ago with a 231 buick v6 with stock exhaust manifolds and it fit fine, but thats a smaller motor

here is my start on a 72 ls build up, I kept the stock pan, I am also going with a rack of some kind? I think my fbody exhaust would have worked if you cut and turned the drivers side exit mounting flange? they are bigger for some reason?
