Mine will be 401ci 3.75 stroke and 4.125 bore. I like a smaller bore size to give the headgasket more clamp from surface area. 4.125 was about as small as I could go to work with these heads.
Thanks! After the car was tuned, the headers turned gold. Stop by our tent at Columbus to see the car. Right now I'm wrapping up a twin turbo Impala project that involved a LOT more work than the GN. Thanks to Dan's (DLS) help on the engine, the customer hopes to set some records this summer.
Cal, I am Expecting an e-mail with details on the tuning session, when you have time of course.:wink:
headers Cal after they turn gold can they be brought back to show finish? Just wondering as Rex is in the process of polishing his TT headers. By the way that is beautiful, but why not a Dart Block? I like old school chevy motors like the darts over the lsx stuff. JMO. Also I see alky on that. Nice
holy cow thats insane.... best of luck with the project, car looks mean with the big snail under the hood
