I have a search for "Sizzler" http://www.ebay.com/itm/MONOGRAM-FACTORY-SEALED-SLINGSTER-SIZZLER-CUSTOMIZING-DRAGSTER-/111304131391?pt=Model_Kit_US&hash=item19ea3e433f
and along with that, if one has an abundant library, one may find most magazines redundant. I agree the magazines mentioned are good but the same money spent on a book on a subject you are truly interested in would be a more wiser expenditure. Just a short list from my library. http://www.amazon.com/TOP-ELEVEN-COBRA-BOOKS/lm/R3HOPU136F8IRG/ref=cm_lm_byauthor_title_full
So how'd you do that? I had a '60 El Camino 283, four speed, three twos, and those headers. plugged em into the stock exhaust first, then a set of side pipes. worked really well.
