what are some part numbers to lok out for for GT40 heads taht will fit my 79 block... also what intakes should i use to get more power i have edelbrock performer 289 intake.. thanks
Are there GT40 headers that fit Mavs and Comets? GT40 has oddball spark plugs angles or something, been too long since I fooled with it.
Part nos. The part number is just GT40-p stamped right in the head, under the valve cover like normal. Made them '97(?) to end(?) of 302. Used on explorers. They'll bolt onto your 302. What I've read, looks like the Weiand Stealth may be the best intake, but various good ones, Performer is on the bottom end of the list. If you haven't been to the Windsor Family of engines site, you should. I'll post the link. Whoops, you said gt40's, which are different than p's, and not quite as good, the early version, early still being the 90's. They are the ones with y303 in the part number. Site below still applies, search gt40 and/or gt40p and you'll get good info.
