1989 Indmar 351 Manifold and Riser Replacement (Need Torque Specs.)

(1/1)

Baybilly:
Hey all, I just ordered manifolds and risers for my new to me 89 Advance. Does anyone know what the torque specs. are for the bolts (manifold and riser)?

Thanks in advance.

backfoot100:
Manifold to head torque on my SBC was 25ft/lbs. I have no idea about the risers though. I would think 15-20ft/lbs would be more than sufficient based on bolt size. Having a clean, straight surface at the manifold/riser junction would be far more important to a good seal.

Baybilly:
Thanks for the recommendation!
