The E'brock Pro Flo 2 will have more of an Old Skool look as well.

I think most people who are not racing, and still spending big bucks on the drive train, are looking for smooth power like you might get in a Mercedes. Nobody should be thinking you cannot drive around with that cam. I have built similar engines and know what to expect from that. The inexperienced might question if something is wrong during first operation. That build is not going to sail at 19-21 " of vacuum. There will be vibration and sound problems, that is the nature of the beast. When I get contracted to do a " pimp my ride" for a local, they are expecting it to perform like a video game more or less. At certain power levels their are compromises to be made. It isn't a how much hotrod can you handle deal ,either. It is more what works well after you tried it all.

"Can" and "should" are two different things. Based on a 6000rpm chip he has about 20 degrees too much duration. Less duration would equate to a quicker car, better durability, and better mileage. But you'd lose those dyno queen numbers and sound. It comes down to wanting "show" or "go". Nothing wrong with show either, it's what inspires most of us.

. Vinnie, pardon my ignorance, but what do the numbers 1,2,5 represent at the end of the cam specs?
Thinwhiteduke, I don't think this was ever answered. 1 is "Stock valve springs can not be used.". 2 is "requires thrust button.". 5 is "Requires upgraded distributor gear."

Vinnie's recommendations are usually for Howards Cams (with good reason). If you download the Howards catalog the numbers for the notes are on page 96.

Thanks Ed, na I didn't get a clear answer on that, I assumed from Vinies reply that it had something to do with the fact that it was a custom grind.
Thanks for clarifying that.

I looked at that fi Vic Jr. intake they have but the power curve starts at 3500 rpm. I had a standard Vic Jr. on a 350 Chevy with a small stall convertor and 4.10 gears. It was in a 55 Chevy stepside and moved out pretty well. I never felt that it was short on power down low so the 3500 they start the power curve at has me a little skeptical. Especially if it was running mpfi.

Megasquirt makes a controller for 4l60's and 4l80's too called the Megashift. The prices on all this stuff isn't really that bad. I'm sure using the stock stuff and reflashing it would work but think the Megasquirt stuff would be less of a hassle.

Their newest MS3X system is self learning too if you set it up with a wide band 02. You load it with a curve that is close to your engine combo and then it tunes itself from there. Another thing I like about this system is that if you are running a mpfi manifold you can run it sequentially instead of batch mode like a stock system. It seems like you would get much better drive-ability and power.

I'm not trying to talk you out of using the stock computer but didn't know if you knew about the new stuff they had available. It's definitely not the cheapest but the features that are available make the system really tempting. There are multiple systems available so you kind of tailor it to your needs.

The MS3X also comes with built in bluetooth so you can run the software on a smart phone if you wanted to.

I've seen the ads for the megasquirt,but,haven't looked into it very deep.I will ck it out tho.Sounds like a good deal.There are lots of options out there.I like the Fast EZ EFI as well.You would think with all the competition that prices would come down.LOL.
