3 inch exhaust too much?
The machine shop told me my engine sould be running about 10:1 compression with my 2.02 double hump heads .40 over 350 with a mild port job. They also told me a 3 inch exhaust with an H pipe will be the ideal exhaust set up for me.
I'm all for the H pipe but 3'' inch exhaust just seems like alittle much for the said engine you know not enough back pressure?
