1970MonteMotion Posted January 19, 2012 Share Posted January 19, 2012 Hello. I have factory 300HP 350/ and factory 350 tranny. I am going to add headers, and it currently has 650 holley double pumper carb. For now, I only plan to add headers, stall, shift kit, cam and lifters, and intake. The car idles now just above 1,000 rpm. No more than 1,200 rpm. My aluminum intake will be functional somewhere around 1200-5500 rpm. The cam will most likely be a .489/.504 lift. Duration 268/276 with a rpm range of 1800-6500. Lunati Voodoo. My question is, would a 3,000 stall be too much? Would a 26 or 2800-3000 stall work better with this set up? I plan to change my rear end gears to 3.73. Does this set-up sound logical, or ? Quote Link to comment Share on other sites More sharing options...
BowtieThunder Posted January 20, 2012 Share Posted January 20, 2012 well no reason for it too be idling that high..... why do you have the idle set there??? Not sure you need a converter for your setup Quote Link to comment Share on other sites More sharing options...
amsterdam84 Posted January 20, 2012 Share Posted January 20, 2012 Idle on a sbc 350 in gear on an auto is around 650 rpm isn't it? You may have pull back your idle screw. Quote Link to comment Share on other sites More sharing options...
1970MonteMotion Posted January 21, 2012 Author Share Posted January 21, 2012 In neutral, my car looks to idle just under 1,000 rpm. Not sure of the reading, but the rpms drop when in drive. Sorry for explaining it wrong the 1st time around. Quote Link to comment Share on other sites More sharing options...
