I haven't gotten it out on the the road yet, I am trying to get it so that it wont foul the plugs at idle. The reason I am thinking it is a reversion problem is the cam has a 108 degree LSA so it has a lot of overlap. I might have to go out and run it hard to see if that cleans up the plugs. I...

Sorry I haven't posted in awhile. Got frustrated and gave up on it. The plan at this point is to drill the butterflies to .150, and add the wire restrictors, then go up 1 step hotter on the plug. The headers are open right now and at this point I am wondering if I have a reversion problem. Any...

OK this is were I'm at now. I changed a plug and set the initial timing to 16 degrees, curb idle vacuum at 13", 1 1/4 turns out on idle mixture screws. Pulled the plug that I had changed and it is still too rich. Plug is dark brown. It is better than it was but still not optimum. I am going to...

Sounds like the same issue. I don't know what is up with Holley anymore. Used to be able to buy one off the shelf a be very close on tune. I did read that they have reengineered the fuel curve on some of the new carbs. Sounds like they messed up the idle circuits on them.

Yes, all 4 corners are acting the same now. All channel restrictors are machined in the blocks. Not changeable. I think I will be able to tune it now. I just need a few days to work it. I will let you know what I run into. Thanks.

I know what you mean about Holley QC. I didn't mention it before but when I first pulled the fuel bowls off I found that they were kind enough to leave me an extra float pivot screw inside the bowl that was jammed in the needle and seat mechanism. I took care of that and it ran a little better.

Update: I removed carb and pulled it down, changed power valve back to 6.5 now that I'm getting 13" of vacuum. Jets are now 70 on the primary's and 73 on the secondary's Drilled all 4 butterflies with .130 drill bit. Now idling with 15" of vacuum. Idle screws have a profound effect on the idle...

Doesn't die but runs rough. Also the mixture screws aren't consistent when turned in, 3 of them have a definite effect on idle the other 1 has a minimal effect which seems to me to indicate an internal leak but I have replaced all the metering block and fuel bowl gaskets.

I have already rejetted the primaries, factory jet 73 now 70. Factory power valve 6.5 now 4.5 because vacuum was at 9 until I started to tune this. Ignition system is all new with an MSD Coil and a MSD ready to run distributor. Initial timing was bumped up to 20, total 32 all in by 3500 RPM...

Here is a pic of my car. I just built a 351c 4V factory iron heads with a Torker II manifold and a Holley 76750BL Ultra Double pumper carb. The carb is running too rich at idle to tune it. It is fouling plugs after about an hour of run time. I have ruled out vacuum leaks in the lifter valley and...

OK, so this is what I am thinking. I have all the pieces to put the power train back to correct specs. It is an AC car so now I have what I need to get the AC system functional again. I will be able to make the ram air functional. I will do a freshen up on the engine with full floater forged...

That's what I figured so I went ahead and bought it. Thanks for the compliment.

I found a 140,000 mile Cleveland with the AC compressor and hoses and all brackets with a rebuilt FMX for $900. What do you think?

Thanks for the compliment. No, the person that owned it before me did the paint and bodywork.

I thought about going back to the Cleveland engine and if I can find one for a good price that might be an option.

Cleveland heads are a much better design than the Windsor heads. I run a 460 stroked to 501 cubes with the Blue Thunder heads in my dragster and those heads are just a scaled up version of the Cleveland. They can be made to flow very well. Although I do not plan to race this it makes better...

How much for the steering box?

Pretty cool site. I haven't had a chance to really look through it yet but the people seem pretty amazing. By left bank I mean left exhaust pipe. I am thinking of building a 351 Clevor for it. Edelbrock makes some nice aluminum heads and intake for this combo. Possibly stroked to a 408.

It seems to me that I have heard of the C4 being offered in the big block pattern although I think that they are fairly rare. The racers love them for the weight savings.
