According to Charles Servedio the airgap intake flows only 220cfm (worst port). Does new high flowing heads help if intake flow only that? I dont know just thinking.

How did you figure out that ignition might be weak? I did a voltage measurement from ballast resistor that is blue ignition on- wire. While ignition key on, it showed excessive voltage drop about 2 volts (between battery and ballast resistor). I have already bypassed the bulkhead connector from...

Not sure what happens at beginning. Acceleration pump seems to have its own issues, when I press gas lightly at any speed it goes momentarily leaner and after that start to accelerate properly.

Here is graph from datalog. It was 2. gear wot acceleration from 2000 to 6000. Datalogger wasnt working properly because it took samples only 4 to 8 times per second. I have newer played with air jets or emulsion jets before. Lot of new information to think. I appreciate your input.

I dont have pin gauges yet or measured the empty emulsion holes. Air bleeds were marked with numbers but IFR jets and "powervalve jets" were not. Actually I made my own datalogger with Arduino that took afr reading 10 times per second. I try to find the log file and see if its showing something...

All numbers are what I have personally measured. Except cam degrees.

I occasionally like to drive it hard. I bought the afr meter to get most out of the new carb. And if I could get better fuel mileage that would be a bonus. Im aware that afr meter might show falsely reading in idle with big cam overlap. I tuned idle mixture with vacuum gauge to get maximum...

Few years ago I bought new Brawler 750 double pumper carb BR-67213. I was driving happily until this summer I got a wideband AFR gauge. I was supprised that according to the gauge it was running very rich at wot. Something around 10 afr. Stock jetting was 76 front and 80 back. I gradually...

Reminder: That book has some wrong torque specs in it so I recommend to double check them from elsewhere if you plan to use them.

I ended up using my old double springs. They had about 10 percent less seat pressure than comp cams recommend for that cam. It worked fine.

One of the 4 long bolts is longer than others. I once stripped the treads because not noticing that. edit: not sure anymore looks like there is 2 long and 2 shorter. 1960-1976 All Makes All Models Parts | MM8276 | 1970-74 Mopar A / B / E-Body 318 / 340 / 360 Small Block V8 9 Piece Water Pump...

Is it possible to change front band lever while trans is in car with engine? I have stock size converter. There is a plug behind torque converter that needs to take out but looks like it is not possible without taking engine and trans apart.

What headers you have? My quess 419hp

312 RWHP is my guess.

Here is table where you can see percentage of power gain. https://www.musclecardiy.com/cylinder-heads/maximizing-cylinder-head-compression-ratios-power-part-12/
