DriveTrain / Re: Help. 400 heads.
« Last post by d123gt on April 22, 2014, 04:22:42 PM »
I have found 3 heads local #13 #16 and #62. I am leaning away from the #16 because it has broken valves. so i am going back and forth on the 13 and 62 is there an advantage to one or the other.

I am certain your problem is the 1411.. a 750 cfm EDELBROCK is propably way too rich for the engine to ever pass. Seriously... on top of this the Edelbrock/ Carter AFB design is not the most sophisticated.
Back in the early seventies GM phased out the Carter AFB because it wasn't sophisticated enough internally to meet the ever tightening emissions demands... This is why GM used the Qjet only.

I may very well be wrong, but my guess is that your 750 cfm Edelbrock is the cause of this. Get a Properly set up Qjet, get the timing set stock and you will be fine.
Where have you set your timing ?

It may be wrong, I am not claiming it to be the 403 bible :-)
My point is, OP needs to get his initial up about twice as high.
Grand73am: how high did you set you initial before your idle deteriorated?
The biggest problem with the stock HEI is that the vacuum can advances the timing alot. You can seldom set your total up to the desired mid 30's for best power without running into detonation, hesitation and suffering idle, because the vacuumcan usually gives about 25 degrees of advance.

Thanks Geno Thats what I was thinking. I did find a set of #16 heads that have been ported and polished but need new valves and screw in studs. what would be a good price for these. Would I be safe to run dished pistons at 9.7 to 1 on these heads.
No. 16's are good heads and typically have a 72-75cc chamber, but you still need to have them cc'd so you know exactly how big the chambers are. These heads will yield a 9.6-9.8:1 SCR- dish pistons will lower your SCR to a more acceptable 9-9.5:1. Expect to pay around $200-300/pair for these cores.

If you're planning to buy forged pistons and rods anyways, you could also consider getting a stroker crank- then you could use your 6x-8's, get more cubes and hp, and still run pump gas.
