I'd like to see many more pics....?????? please.

Nice! Now... how much did it cost for the intake conversion?

Well normally there is a good difference in power and TQ output over a Vic Jr, and the castings are pretty similar in price for the basic Super Vic vs. Vic Jr. The design of the Super Vic gives a much better entry into the heads for beter airflow and better tuning. If you have to go thru so much to get the intake converted over to fit, might as well start with the right intake casting.

Ron traded Ben for that intake so got me to what it cost him? I know what they normally cost.

How do you go about tuning with the 90mm LS1 TB on there? Will the stock computer accept/work with the big tb?

Camarocracy

I'm sure he went with a custom tune seeing as he has a 383. Be kind of stupid not to go with a custom tune and make the LS1 tb work to it's full potential and increase the power band.

SStrokerAce

The LS1 TB allows the IAC and TPS to be the same basicly. Some guys have even used Ford 90mm aftermarket TB's like a Wilson Manifolds one and they have worked well. The biggest difference I have seen is the fuel injector setup and if that is done wrong it's almost impossible to tune, I've seen this with other converted manifolds but not mine and that seems to be the big difference so that's my best guess as to the problem.

So you are saying that if the conversion to injection is botched, or the intake is not set up right, the tuning issue lies there right? The reason I ask is I will probably go this route in the future and was wondering if the tunercat program will get me by until I upgrade the whole injection system.

SStrokerAce

What else are you going to upgrade?????

I think LT1edit and Tunercat work fine for this now. The stock ECU is actually the best system out there other than the RPM cutoff.

Yea, the rpm cutoff. I wish there were some way to get past that with OBD1. I was just looking into the conversion for more power. I have an all forged bottom with splayed caps, solid roller, decent heads and everything else needed for the extra power. I'm not a nitrous guy...yet, and I'm looking toward the future with the setup to possibly supercharge or turbo.

That's an awesome looking setup!!!

I'm sorry, I didn't get what you were asking. Are you telling me that going to a FAST or DFI isn't worth it for the additional fine tuning? If so, then I WILL keep the stock setup because I don't want to spend the extra money.

redneck01

that is a nice nice setup.

SStrokerAce

Actually there is LESS fine tuning with that over the stock ECU. The ONLY advantage to a aftermarket ECU on a NA LT1 is the additional RPM range for the fuel and timing curves.

FWIW the intake is the only thing left really to do on a NA motor.

Is the swap worth it without the capability to go above 7k?
