Old cast iron manifolds on new vortec heads....will they fit? I know the intake manifold is different but I'm not sure about the exhaust manifolds. I know it isn't the best option for performance but fitment and budget are more important to me right now than giving up alittle performance.
I'm looking at a crate engine from blueprint that has vortec heads thats in the price range.
Whats brought me to this point may be entertaining or a good lesson (or both) for others......I put a new intake with the Holly Sniper, Hyperspark distributor, ignition box and coil on an existing engine. Super simple install....ran through the initial programming steps and fired the engine. Sounded great right up until the point that the valve cover bolt that somehow snuck into one of the intake runners made it past the valve and into #3 cylinder.
While I was tearing it back apart I knew exactly what had happened......I left the valve covers on when swapping manifolds but the new manifold wouldn't drop into place with them on. I pulled the passenger side first and then the drivers side which got hung up on some wiring in the rear. The bolts all dropped when the it finally came lose and I found all but one. I asked my son if he saw anything in the lifter valley which he didn't so we assumed it landed on the floor. Apparently not and a pretty expensive mistake that could have been avoided.
