I was pointed to this thread.
I have conversed with Tom via PMs before and at first my thought was changing to the carb intake would not be a benefit over EFI b/c initially I was thinking that RPMs are the limiting factor but after reading the posts made here I am reconsidering my opinion. The thought of taking the intake off and porting it is not stock. And lets think of the intake that is available, it's an LT4 intake which does not match up with the LT1 heads so it has to be 'cut' some to fit/flow properly, in that I do not think that would work. Is there a way to get a carb intake on the car without touching it, as cast? still that might be a bit much since some will say the LT1 intake is a restriction.
Now as for weight reduction, no real issue to cut stuff out of the car, I was going to but never got to that but that is what you have to do when you only make 320ish RWHP.
Since the oil issue was brought up I guess retarding/advancing the cam is a no no even if you were to use the stock timing set (ie cut the proper key way into it...that is something we thought about doing but never did).

I think it's cool to see what people are wanting to do to go 11.80s (or less) and I am willing to help anyone get there, I do think 11.69 is possible but the tune/weather/track and weight have to be just right. I was 30-50#s below the 3180 race weight we measured a few weeks before.

 

Shon, GM Performance Parts sells a direct bolt-on intake for the LT1 engine, it requires nothing to be done to it. Summit sells them for around $250.00.

 

hmm, I thought that was the LT4 intake to match the LT4 heads.

Let me re-iterate what I was trying to say before, the RPMs would be a limiting factor no matter what, the stock 97 cam will not like going past 63-6400 RPMS, it gives out of breath, we tried a few times to push it that far on the top end of 1/8th mile tracks.

Also added note, ET Drags are slightly shorter than ET Streets, and we gained some RPM on the top end when running those.
Record pass was on ET Street though.

 

Hey Shon,

Thanks for dropping in...

When money comes around for me I may take you up on that offer to help out...

 

for some reason i just think u should have a stock intake

 

AFAIK the official stance is that you can run any intake with fuel injection that's run by the stock computer.

 

who is the official?

 

Who ever gets beat

 

At that time it was the editorial staff at GM High Tech magazine.

 

whoa i think that shut s all up

 

Of course everyone has their own opinion and ideas of what should or should not be allowed, but look at it this way, if you do not allow intakes, there would be perhaps 130 cars roughly that would have an advantage over all the others right off the bat. All the LT4 cars, for instance. And true, there may be not a one of them battling this out for dominance in the bolt-on world of f-bodies, but it could happen, and then you would, from the factory, have an "unfair" advantage, so to speak. Then you could also argue the 1LE cars, the list goes on...

I am not bashing you as you bring up a good point as to where to draw the line on what should be allowed or DQ somebody from this competition, but look at organizations that have battled in the past about a number of issues, like the NMCA. They all run mufflers, are all the cars participating running them? How about back-halved cars? 9" rear vehicles? Lenco/TH-400's, etc? We could all go on for days on what would or could make something potentially quicker, when all everyone, likely agreed, just wants to see a competition of unmolested, stock longblock, full-bodied f-bodies battle it out for who is quickest based on driver ability, skill, and their abillity to do more with less, IMO.
