Ya ,I would like that, I need ideas to figure out the best route to take with the set up.

327 or even 350 probably more practical for high revs but you'll get the tq with the big motors...

Sounds like a fun project... I know a few guys at our track that run the Vegas. They're great cars... I'll keep an eye out next weekend to see how they have the rears set up but I don't think we have any running faster than mid 10's in the 1/4 (most are running 11s-13s)

Really , like this guy. Its a monza but pretty much the same. http://www.cardomain.com/ride/2035660 This guy moved suspension components in a couple inches and uses a 10 tire, it looks good.

PM sent to you

This car is not mine but the owner is useing the srock front and rear set up. Looks like its working.
I have pretty much all the same setup. 406 edelbrock heads, 170 shot plate system, th350 3800 stall, 12 bolt with gm posi and 3.73, 26x8.5 MT's, I have a sway bar, airbags in both springs run them both at 25psi. The car leaves extremely hard 1.47 60ft times. It still has the stock upper and lower control arms that have been boxed. The only reason I put the bags in was cause the car was squatting so hard that the pinnion was hitting the floor board. It has went as fast as 6.79 @ 102 in the 8th. I have alot of passes on the car with all the stock suspension and have dialed it down pretty good. The car is in the garage right now, I took it apart to freshen it up and put a bigger solid roller cam in it. If you need any info feel free to ask, I can point you in direction that I should have taken when I first started building the car. Ill post some pictures of the car.

anyone contemplated a vega gasser :-?

does anyone know the width of a 400 pontiac? the outside dimensions? biggers or small then a bbc?

I am looking into the true street class which seems like a good route to start. Any opinions with the vega and this class ,I would like to hear. Thanks

This is a quote of what the guys in my area are running in this class. Any idea what engine combo would be compititive in the vega?

I guess you can't use Trans dapt/Hooker front mounts because they are more Engine plate then stock style mounts. Are V8 Vegas allowed in that class? Seems like cheating.

They would probably allow a Vega, problem would be getting the Vega suspension to hook hard enough to keep up with the late model Mustangs and Camaro's with their much improved suspension.... IMO it's going to take a lot of laps and a lot of experience to be competitive, but a low buck Vega with a big block and a glide makes one heck of a good bracket car....

It's a fun class, but not a cheap or easy class to be competitive in. There's enough limitations on engines that it comes down to getting the chassis to hook hard and consistently.... We tried it one year, then went back to Super Gas (9.90 class), liked it a lot more and could run a lot better components to keep the car dialed in. The one thing I don't like about the class is all the weight breaks for this and that combination.

I don't see any way you can mini tub a Vega and keep the stock lower control arm mounting locations. My lower rear end control arm mounts are welded to the Moser housing ends and I can't get anywhere close to that much tire under mine. The wheel would hit the control arm.
