318 1/8 time improvement
Update!
I ended up getting a 2800 stall converter, and ditched the 650 AVS, installed a Holley 600cfm VS
And some tube headers!
The converter really woke up the combo the car launches really hard I can tell this will be a huge benefit!
Got rid of the 650 AVS it was way to big for my engine, I had to have the secondaries adjusted really tight to not get a bog, with the calibration kit I had to lean the carb out it never ran right out of the box or when I tried to tune it!
So what did I do I went with a smaller carb The Holley 4160 VS right out of the box this carb did not have a WOT BOG idled well and ran okay on the top end you could tell the secondaries were opening slow and we’re lean.but with any carb your going to have to tune to get performance.
First I swapped the rear block with a plate and added .074 jets to the secondary,the front are still stock .066
Second I added a 35 size nozzle to replace the stock 31.
There was no WOT BOG and the car pulled hard but until the transition to the secondaries
Third and last thing I did was add a quick fuel adjustable secondary vacuum pod, started at the base line of 1 1/2 turns backed it out and test drove it until it bogged at 6 turns out the engined bogged, went in half a turn a time and ended at 5 turns.
I have never felt this engine run the fast and pull this hard! I never messed with Holley but reading and watching videos I got this carb dialed in quick.
Long tube headers! Well what can I say I don’t think I’ll ever run manifolds in any of my small blocks! I gained a lot just from that swap!
