If your combo is correctly matched for that intake. It is a monster. The carb you have is a good match and probably needs some adjustment for good wide open power.

If you want a satisfing ride you might want to rethink some basics. Not that what you have cant work. The opposite can be true too.

My idea is to start stock and build up. A step at a time. You teach yourself how each peice effect the cruise and the performance aspect. Sell the old on ebay, when you advance. You will get to the ideal ride. Kind of novel, but my thing as been a mildish engine, and everything I wanted nitrous to be I found with supercharging.
I actually traded a car for this and think I got the better deal for sure. I have a decent idea of performance cars but learned mostly on fuel injected imports. This whole carb and distributor thing is new to me. However I did have a twin turbo Nissan 350Z that went in the 10s that I built and tuned.
I think I am just over complicating things when learning old technology..

If you want to really tame that thing... a good EFI swap would really help, and I assume you have experience in that area.

A custom built top end carb could greatly help as well, but price one of those and then price a EFI conversion.

I was actually tossing that idea around,but which system is the best one and most reliable?

look into "Big Stuff", problem is you need dyno time to set the fuel curves

Less dyno time than a carb would require. And most dynos only allow you to set WOT fuel curves. The rest is done on the street by logging your data- which is much easier with EFI than a carb.

I like the MS systems. For all the bells and whistles you'd need an MS3 unit, but an MS1 unit would provide more/better tuning capability than a carb.

You'd also need a high pressure fuel pump, and either somesort of TBI unit or a new or modified intake to run multiport.

Video of idle.

On a side not base don the previous conversation with the 11.3 compression and the timing locked out at 34 degrees would I be able to run 93 octane pump gas cruising around locally?

If you can afford a car like that, you can afford to put the correct fuel in it.
Well the $$$$ is not the issue, I can afford to drop 100 octane which we have at a gas station 3 miles away, but the issue is when I cruise it to a show and may need to fill up somewhere else in a pinch..Would running 93 in a pinch when cruising home be a bad thing? I have a 15 gallon cell and am assuming the car would get about 5 mpg so it limits my distance I can go.

I actually dont know have'nt checked that yet. Pretty much still set up the way I got it. Im assuming it needs and adjustment by now. Would you go by the cam card recommendations? I normally keep my valves around 20-22 thou, cold..

different cams have different lash settings. It sounds like a loose lash cam.Im guessing 028 ish? by the sound. 93 octane will work and you should get 10 MPG at 65 ish in high gear

Hey Vinnie, Since you have a similar set up, what do you think the usable power band is and what is my safe redline?

My engine made peak torque @ 4750 and peak HP @ 6500 there fore in my application the engine is fabulous(just my opinion) from 4,000-6800. You Cam is about the same as mine.You have a bigger intake and a little smaller engine.I would guess that from 4300-7800 would be a use able range,especially if you road RACED. I wouldnt spent a lot of time at 7800 with out shaft rockers,though Im sure your girdle system is just fine.The only thing I would even consider changing on your car would be a 5 speed. Your car is more race oriented than mine. probably makes as much or more power too.
I would have a couple chips for your ignition too. a 7500 RPM chip would keep that engine glued together with it bordering on too much power for daily use and not rain friendly.
Have you driven the car hard yet?
