Scotty2Hotty Posted August 2, 2008 Report Share Posted August 2, 2008 I've got a warmed over set of 390 heads from a 69 AMX, but wanted something a little more. The valves are 2.02/1.60 at the moment, but I wanted to step up to the edelbrock performer RPM head which is still a 2.02/1.60 head with a 54CC chamber. I have contemplated some Indy heads, but would need to build atleast a 401+ci to slap the 2.25/1.81 valve heads on, not to mention have another cam ground for me. I'd like to stick with this 390, since I've got a few, wanted to know if I can go bigger on these stock 390 heads, or try the Edelbrocks out.

72POS Posted August 3, 2008 Report Share Posted August 3, 2008 Scotty, why are thinking of the upgrade? are your current heads have dog leg x/huast ports, or retangler x/ports? the dog legs flow a bit better and they use 1/2 headbolts... you can get a set of Iron heads to flow very nice, with out the extra cost of eldys. or Indy's.. wanting more< street car or Race type car? need alittle more info on what you are looking to do..

XChris1632X Posted August 4, 2008 Report Share Posted August 4, 2008 ^^^^Listen to this guy. If you have questions about an AMC from what I have heard he is the man to talk to and from what I have seen, all of his cars are no bullshit.

Race car with a little street driving. It's been a few years since the headers have been off, so I'll double check that this week. I notice the stock iron 390 heads are quite nice, I didn't know if I could stuff a larger valve on the head or not. I've got a few ideas swirling, but most all boil down to getting it running and down the 1320 next spring. Will post pics shortly. Quote Link to comment Share on other sites More sharing options...

Werd. I liked Indy's intake manifold too, it looked like a Edelbrock Victor on steroids. Quote Link to comment Share on other sites More sharing options...
