383 into 67 Barracuda stock - input stock exhaust manifolds (69) vs Schumacker headers
You can see why this is not as easy of decision as it appears. Everybody like more HP, But if the HP units are fairly good, they certainly seem like the easier approach and will look nice when blasted and painted. Car is for street use so I am not looking for Big HP. Sounds like you had very good luck/performance with your HP manifolds. Good to know as I already have these and not take much to paint - even have gaskets with the rebuild kit. Did you have heat riser hooked up (passenger side)? I am missing spring and weight.
I also see head shields for plugs on some pictures of these manifolds. Did you use those?
Thanks again for your input.
Best regards,
Bryan
Very good points.My 69 383 ran mid 7's on the 1/8 with factory manifolds and full 69 factory exhaust.
Street use, stick with the cast iron! No need to mess with headers and some of the headaches they can cause. Factory style plug wires and easier service!!!
