I second that. On my '77 I replaced the stock manifold with a Shankle header and when I stepped on the gas for the first time it jerked my head back. The stock manifold is so restrictive that I couldn't put my thumb in without it touching the top and bottom at the same time.first thing is to get a two piece exhaust manifold and get rid of the air pump
Unfortunately everyone I've seen has been installed with holes. I hate them as well.Does anyone know if the trim strips that run down the side are stuck on or if there are holes? I hate those strips
Well, '73's weren't exactly hp monsters either. As others have written, you should aspire to > 1973 performance levels. Think about cams, head work, higher compression pistons, h.p. ignition....Does anyone know what is required to do this? is the suspension also higher?I am in CT and think that its not a problem for emission. thanks Richard
I think Wes stated during the Seattle convention that if you wanted performance, then you should start with a 74 core and not a later one. In fact, I understood him to say it is better than earlier ones too, if I can trust my poor memory. Apparently they are similar but somewhat different. Since he also said cores are not worth much of anything as far as his buying them, I gave away my 78 pump and related parts yesterday, rather than continue to store a brick.Does that mean that they can be retuned , or that the units are different?
