Ok awesome thanks Jim

Hey I have a 63 riv 401 nailhead what kind of motor oil should I use Jim

Ok thanks I appreciate it

The only one I was able to find online is the one with the built in heat riser can I use it on my engine ? The one that came off was bolt on. I have a 63 riviera but it has a 65-66 401 in it Block code is MT

So my bolt in heat riser broke in half does any one know if a place I can get a new one or get a delete kit I have been looking everywhere and no luck -Jimmy

Hi john Do you have any manifolds left I need the passenger side for my Buick 401 nailhead can’t find one anywhere it has the bolt on type heat riser
