On Monday 2/3/2020 i will have an opportunity to dyno my 496 with the Straub cam and AFR315. The shop doing the dyno session is graciously providing me a chance to figure out what parts I have make the most power.
current: 4.31 bore Gen V gm block, 10.3:1, autotec 21.2 cc domed pistons, Molnar tech rods and crank, vic jr intake, 1050 4150 cfm carb,msd distributor, 2 1/8" primary tube hooker headers, Morel lifters, and Straub Hyd roller cam. The will be a belt initially to only run the water pump.
We are going to run it with the mid pipes like I do at the track when I run open. With the Fitech i need at least a collector extension to accommodate the o2 sensor. Get it dialed in and average 2 pulls. After that we intend to test the following.
Set 2. Add flow master mufflers (my drive around mufflers) NOTE: I have seen my ET improve by as much as .37 seconds by going open header.
Set 3. swap to Dynomax race masters with similar length pipe. never been on the car but are certainly a candidate pending the results
Set 4. Alternator tests. I feel like mu high amp Powermaster cost me some power based on ET last fall.
Set 5. Lower amp duralast that I ran up until the powermaster was installed in August 2019
Set 6. 10.3 compression, 496, afr315 heads, Sniper jr, 2 1/8 headers, mid pipes, 4500 dominator
Set 7. 11:1 compression 496, ported afr265 heads, team g, 2 1/8 headers, mid pipes, 4150 1050 cfm QB main body carb
All testing with the Straub hyd roller. I'd like to start 2020 with a 700 HP NA deal and spray when needed.

Some different guys with small businesses helped me so I'd like to figure out a HP/TQ type contest to give away some of their t-shirts. TBD
