I am getting ready to install the new rods and springs in my AVS2. I have the complete eddy spring set and my research shows to pick the spring that is rated at 1/2 of your vacuum at hot idle in drive for an automatic. Does this sound correct? Thanks for the help in advance!

I think I know the answer to this but I have been wrong so much lately I need confirmation. My combo is LD4B intake with a new 500 cfm Edelbrock. I ordered the insulator gasket not knowing they offered two, open and middle separator. I installed mine with the open gasket but being 1/2" thick I...

Anyone here have any experience with the new Edelbrock AVS2 carburetor. I need a new one and want the make the best choice for my 273 Commando build.

273 commando build with ld4b and holly 4150. Timing 12 initial and 36 all in. 904 with 3:73 8 1/4. 5.5 PV with 52 primary jets. My wideband is dropping to low 12's leaving stop. Comes on hard about 1500/2000 and adjusts to high 13's to mid 14's at cruise. Wondering how to lean it up off idle...

Today I changed jets in my Holley vac secondary 4V carburetor. I removed the front float bowl and the front metering plate, set it power valve down on my bench and changed the jets down 2 sizes. When I picked up the metering plate I saw a small steel ball about 3/32 in diameter laying there. I...

I just test drove my Barracuda again with a working wideband. Up to temperature I consistently saw 11's and 12's. Not much above or below that regardless of RPM or load. I don't think the secondary's ever kicked in. The motor is a newly rebuilt 273 4V-904. I am wondering what numbers I should...

Today I was checking out my new 4295S AFB core and decided to check one of my two newly purchased air cleaners. Neither fit as they are 5+" hole ID and my Carter is 4.5+_ OD. I guess my little Holley would work but I really want to try this Carter. Does anyone make an adaptor or will it be a...

The original carburator for my commando engine would be a Carter AFB-4295S. I was thinking about looking for an original and rebuilding it but thinking it through it looks like the better choice would be and equivelant Eddy 500-600 CFM carburator. I would be interested in any Eddy part numbers...

My 67 notch is a bucket seat, automatic with console car. In my quest to properly tune the sensitive little V-8 I ordered a digital A/F kit with a 2 1/8" LED guage. I am thinking of customizing the console to install the guage at the dash end of the console on a 45 degree angle so I can see it...

I beadblasted my new to me Eddy D4B intake for my 67 273 and discovered some pitting on the intake manifold gasket surface, looks like from water leaking from the cooling passages. I am thinking of taking it to the machine shop and having the intake surfaces machined to clean up. Is there a safe...

What is the thought for an Eddy streetmaster 318 intake for my 273 build. I have concerns that is a single plane but I have found one. I am searching for the stock commando or an Eddy LD4 but they both are very hard to find. Will I hurt myself with the streetmaster 318 intake? TIA, Rat:prayer:

The carburator on my 273 is a Ball & Ball. It has been rebuilt by my mechanic but has not performed. Now it is flowing fuel out the top like the float wont hold and loading up & flooding out at idle. Can this be tuned or do I need to replace it with another 2v carb of another brand, and...
