I'm fine tuning my Edelbrock AVS 650 Thunder series carb and I'm showing 10.5 A/F at WOT on my wideband and I was wondering how much a 1 step leaner jet for the secondaries would affect the A/F. I read somewhere that 1 jet size is 0.5 A/F point but I'm not sure if that is correct for this carb.

I'm running lean under load (going up a hill at low RPM), what do I need to change to richen it up a bit? I have installed a A/F gauge and here are the readings i'm getting: - Idle is around 13 - 13.5 - Part Throttle (Highway driving) 13 - 13.5 - Full Throttle 10.5 - 11.5 (so too rich, should...

I just installed a AEM Wideband gauge and I'm looking for some ballpark numbers to tune to. I looked online and was wondering if the below numbers are a good starting point for my combo. A/F Ratio @ Idle: 13.5 - 14.5 A/F Ratio @ Cruise: 13.5 - 14 A/F Ratio @ WideOpen: 12.5 - 12.8 Engine...

just swapped intakes (torker 340 to a Edelbrock Air Gap) and I am trying to calibrate the carb (edelbrock 1806 Thunder series AVS). I richened up the carb a bit because I thought it might have been running a little on the lean side, now it won't idle below 1000 rpm (at highest vacuum reading...

I am having some problems installing my new edelbrock air gap intake (bolts don't line up with thick gaskets) to my stock J headed 360 engine. I have another thread going on this forum called "Intake won't bolt on!". The consensus seems to be to either mill the intake or try to use a thinner...

I'm just in the process of replacing a torker 340 with the RPM Air Gap. I removed the old intake, cleaned all the flanges and installed the correct type edelbrock intake gaskets. I put RTV around the end seal flanges and placed the intake on the engine. The bolt holes seemed to not line up...

Hi, I'm just in the process of replacing my old torker 340 intake with the Edelbrock RPM Air Gap. I have the old intake removed and i'm now cleaning up the head flanges. I noticed these small tabs (see picture). It looks like they are from the head gasket. They are present on all four corners...

I just received my Edelbrock RPM air gap intake from summit racing (new in original packaging) and after opening it I noticed it doesn't have the Edelbrock logo anywhere on the intake... It does have the casting number 7576, the RPM Air Gap logo and the Made in USA sticker but I find it kinda...

I'm planning on finally buying the #7576 Edelbrock Air Gap for my LA360 Currently I have the Edelbrock torker 340. Does anyone think the Airgap is the wrong intake to run in a slightly colder climate. I live in Newfoundland, Canada (Spring/summers usually between 10-20 degrees Celsius maybe a...

I took out my old fuel pump yesterday and tried taking off the short piece of hard line (on the output side of the fuel pump) that connects the rubber line to the carb. When trying to take the hard line off, it stripped the fitting. Would i be able to use a AN fitting directly on the fuel pump...

Hi Guys. on a hot day when the engine temp gets around the 190 mark on my 67 barracuda the car sometimes seems to be starving for fuel. I recently put a fuel pressure gauge in and last night i noticed the pressure dropped down to 2 psi right after i gave it some throttle while the car was...
