Timing Retarding @ high RPM

I just talked to a MSD tech and asked them about the retard that would come in at higher rpm's. He said only if I have a timing retarder being turned on with one of my digital switches for boost. Simular to the older Boost master I have for the Blower motor. The older Boost Master takes a Vacuum signal .

He told me there should be no retard unless it is programmed in. I am going to side with him on this He should know. this is all new stuff. Not **** from the 2000's. I never did anything with my adjustments except my rev limiter. I had no trans brake and I never hooked up a bottle. In the foot brake classes I ran you could not use electronics.

It has a MSD digital 6, MSD HVC coil, MSD billet distributor mechanical and it is locked. When I start the motor it idles @34 degrees before top dead center. It stays there up to 5000 when we have the Snap on RPM dial light on it. he won't take it higher in Nuetral. The EGT's were perfect through the quarter mile up to 8000 rpms.

We tried 4 different manufacture carbs . Pro-form 750. no way was that thing working, 850 holley it was rich , We got tired of playing with it. Then a 950 BLP . It had a dead spot in the middle Another waist of $900.

Then Steve put this 1050 Quick fuel on it he got from a dealer to try. Out of the box It was a little rich in the middle. I changed the primary air bleeds two sizes bigger and squared the primaries, Idled off the secondaries. This motor is like an off and on switch. foot brake to 2500 plant the peddle it goes right to 6000. Like its electric and its smooth.

Now I am not telling you what to buy. I am only telling you what worked for me.

Do not cut cost on Timing chain. you can get real good sprockets and cut to fit chains, Do not use a junk true roller with a tensioner. They make good true rollers. Hardened oil pump shaft. and honed to fit bushing,
