M1 Single Plane Question

I agree, you have more issue than just the carb shooter. What is the cylinder pressures for it? you dont know the timing curve. You have to know and get that set properly before you play with the carb. For a typical 4" engine with decent quench and closed chamber heads I will run 18° initial, and I make a bushing for the MSD that allows for a total of 30°. The initial is critical, but so is NOT running too much total. With the good gearing, and low first, even with a 10" 3200 that thing should snap off the line with a small cam and average port. You can dump all the fuel you want in it and it isnt going to get quicker. The acclerator pump is only designed to cover the movement of the throttle opening. The PV provides the enrichment beyond that. What PV is in it? What is your vacuum level idling in gear? there's a ton more we need to know before we begin explaining how our ideas are right and rule out everything else. Never set carb before timing. Never set timing until you know the overall health of the engine.

Sounds like we have the makings of a friendly track test here.

Mopers setup 18 initial 30 total, and the shooters it came with.

Georges set-up 14 initial 35 total and ..040 shooters

You game 69chrgr? lets try them out at the track, correct for weather, let the best man win?
 
Awesome!! Hell yeah I'm game. I replaced the bushing the dist. came with and replaced with the black bushing, therefore enabling me to run more initial w/o too much total. Total timing is about 35 now. My cylinder pressures range from 175-185 PSI. Should I have been running more MPH?
 
Try setting the timing my way,bring the engine up to 2000 rpm's set the timing at 36 degrees lock the distributor your all set....
 
After wasting my money on the M1 I bought a victor 340 intake. This is easily the best mainfold ever made for an LA engine. The victor is better thought out with the correct flange and more hookups for water passages. like temp gauges and even a heater hose outlet the M1 lacks. The M1 now sits on my slot car track holding up the high bank curve. Does a good job at that.
 
I reset total timing to 35 degrees. Installed the Wilson supersucker and dam the throttle response is amazing. I need longer studs to set the throttle linkage up so I couldn't drive it, but after thinking this thing through, I think I'm going to reinstall the 950 and retune and jet it for the Wilson. My discharge nozzles should be here this week along with the studs, so we shall soon find out! Thanks for all the input and I will soon post some results.
 
Hey 69Chrgr,
I had the same issue with my M1 intake and I replaced it with an Edelbrock Super Victor. My engine builder really showed me and explained to me that with the M1 I was not getting good fuel distribution at all and was losing HP. He was going to send out the intake to get it setup for a Holly DP but then we found the Super Victor and went with that.
