Nice....what are the specs on the cam? Didn't get details on the heads either....

Those pics are conveniently another 383 customers parts. Heads are older AFR 190's w/ 2.00/1.60 70+ cc chambers, they've been decked so they need to be cc'd. Grant's working up some numbers for me. If I can make it happen the cam would be custom grind to his specs, 520 lift range, 10:1 comp.

I hear AFR's are the best heads out of the box. My cam is custom ground with an LSX firing order. Might want to ask yor builder about that. Also, I would recommend a Victor Jr Intake. I used mine on the street for years with a cam that was .250 duration at .050 and it was fine. Especially since your running a 5 speed. If I was running a 5 speed I would probably go to a 3.73 gear.

Thanks for reminding me, I remember reading your LSX firing order, forgot all about it. How much different does it sound compared to conventional?

Grant has been a proponent of the Victor Series for years, but he's the one that sold me on the Air Gap, he said they're producing equal or better numbers, with a slight look of amazement on his face.

I'm running a T56 Mag close ratio, .63 6th. Rear gear will end up at 3.55-3:73 leaning to the later. I tend to prefer a slightly taller gear, especially on my track and offroad bikes. Poor mans traction control. :D

You ever hear the drone from a modified LSX? I get that at a certain rpm. alot of guys dont like that but I think it sounds pretty cool. More like a howl rather than a drone.

When I had my air gap back in the day I dyno tuned my car. Switched to a Victor JR and re-dynoed. The Victor gave me 50 more hp. no lie.

When picking rear gears think about the top speed you will be running at the end of the longest straight of a track that you run at peak or max rpm.

With a 25.6" tire and 3.42 gears 145 mph is my top speed at 6500 rpm. I picked that speed according to Thunder Hill. So far I've hit 6200 rpm at the end of the straight which puts me at around 139-140 mph. A lttle more wheel time and some aero work I should hit my mark.

Since it was brought up, and you are deciding or having decided for you which route to take, I am curious on the differences/benefits of the LSx, 4-7 swap, and "Cleveland" firing orders. I just learned of the "Cleveland" firing order last week (also called the 4 cylinder swap).

:lateral:

I haven't heard the LSx in person. LSx, 4-7 and Cleveland will make for good discussion at the shop.

I've been out of the market a while, how many versions/revisions of the Air Gap are there? Performer and Performer RPM are the two I'm aware of.

My car has a late 80's Torker II on it, the revised version is rumored to be much better.

The Victor on a SBC looks proper :yes:

I'll assume your gearing/rpm numbers are based on 1:1 final drive? My intention is to base the track gearing off the 1:1 4th gear. 5th and 6th are recreational/transport gears IMO. :D

I am aware of the original Air Gap and then one update, but maybe there is more.

I had a Torker on my Pontiac motor in high school. :thumbsup:

And yeah 4th gear 1:1 (I'll answer for G) as I know he has a beefed up Muncie / Spec 25.

The Victor Jr and Super Victor are great looking intakes I agree. :thumbsup:

LS swaps 4-3 with 7-2 in the firing order. I'm no engineer but I'm assuming it's a better arrangement.

Yes, 1:1 final. Running standard Muncie gearing in trans.

Grant put an Offy Dual Plane on Pontiac motor he built for me in '78. :D
