Planning on a Wieand Tunnel Ram install on my T-Bucket, SBC. Currently I am running an MSD Ready to Run Distributor. My concern is whether their is room or will I have to use a different distributor. The folks at both MSD and Wieand (Holley) have not provided me with a solid answer. Any thoughts? Thanks, Jack
If the MSD unit is the same size as the regular distributor it should work OK. There are lots of tunnel ram SBCs out there running the single point GM distributors.
I have a weiand tunnel ram on my sbc the HEI wouldn't fit but I believe any if the smaller ones without the coil on top will fit you should be fine Posted using the Full Custom H.A.M.B. App!
Agreed, the small diameter GM distributor will fir fine, the HEI will not. A bit of experience for you, the tunnel ram is far from an ideal manifold for street use. I had one with a single 4 barrel on a 327 in my 36 Ford sedan. I never could get it to run just right and street drivability was lousy. A switch back to a regular aluminum manifold (same Holley carb) and all was well. It drove very nicely after that.
