Yesterday looks great link http://rides.webshots.com/album/553646077CLCZBu

Looks great :cool:

Look great,if thats a real dz 302 motor did you notice a big difference in perf going from the single 4brl carb to the crossram w/2 fours?

I may be wrong but I would recommend chaning the routing of the booster vacuum. Last time I hooked one up to the pcv system, oil ended up killing the booster.

It is a 383 stroker not a 302 I wanted to be able to drive on pump gas. It does run better on the 2 600 cfm carbs then it did on the 1 750. I was sure it would load up at stoplights and I would lose low end performance but I didn't I believe I gained on both.

Looks GREAT! How did you find, how much did you have to spend?

:beers: for you. Looks great. Glad to hear it works well on the 383. I have a crossram for my el camino (Offenhauser copy, nearly identical, some differences on the top) going on a 377. That manifold in Chevy's testing had a strong midrange to top end power on the 302, should be even better on a 383. Enjoy. :thumbsup:

That is a thing of beauty! I love those old cross-rams. I bet that lightened your wallet a tad bit!

wow! thats bad ass! cross rams are hardcore nice job! :thumbsup:

Back in '69, Nurse Chev-Olds in Whitby, Ontario set up one of their new Z/28s with the 2X4barrel intake and track cam. I had the opportunity to take this car for a short run. The car had 3.73 gears which were all wrong for driving on the street. Under 4K rpms there was absolutely nothing, and very little from there to 5K. This setup was meant for above 5K rpms. The extra cubic inches will probably make a big difference in the lower end torque. When they talk about mid range torque with this setup, they aren't talking about the street rpm range that we normally think of They are talking about way up there. A couple of 390 Holleys on this intake might work better on the street. 4.56 gears and a 6 speed over drive transmission would really put the icing on the cake. It is one wild looking setup to say the least and will sure attract attention where ever you go.

On a street driven 302, the 390's would help alot. The dyno chart in "Camaro - Untold Secrets" showed the HP and torque coming on strong in the 4000-4500 rpm range with best power in the 4-7500+ range. Some people have put the setup on 400 SB and it brings the range down to the 2500-6500 rpm range. I wonder what the 390's vs 600 would do on a large small block, which would perform the best on driveability vs power output. Interesting test for sure.

Its all in how you tune it,if the ign timing curve & fuel calibration are both properly ysetup you should not have loading up issues with the crossram setup ,glad it's worked well for you.

Yes that is an Offenhouser http://store.summitracing.com/partdetail.asp?autofilter=1&part=OFY%2D5893&N=700+115&autoview=sku that someone ground all the markings off (I didn't do it). Summit Racing sell the intake it is a copy of the original winters brand. Yes it did lighten up my wallet a bunch. The linkages, fuel lines and all the other parts were bought at Heartbeat City. The intake was the cheapest part. LOL

You're not kidding about all the parts to go with the crossram being expensive. :clonk: I only have the intake right now, but since it is not a resto thing for me (it's on an elky after all), I don't have to buy the "correct" carbs, fuel lines and such. Still not cheap, though.

Ya the intake is the cheap part it's all the other stuff that gets ya. LOL

I've had two different cars that I ran dual quads on. A bb 468 and a sb 355. Once you get them tuned in, they go as good as they look!

I agree

If I am not incorrect, back in the '70's GMHiPo Parts had one you could pick up over the counter.

I can't remember which one I had, but when I was putting together my 1st Chevelle (65 Malibu 327 in 1973) I was given a 2-pc cross ram for free. I couldn't afford the carbs so I swapped it for a stock GM hi-rise off of a 70 Z28 and a used Holly (think 780, it WAS a few years ago).

I came home from work one day and found it leaning up against our garage door. I kept it until I was cleaning out my parents garage in the early 80's.

Along with a boat-load of other hi-po parts, it went into the trash with my collection of pristine Superman and Batman comic books and baseball cards. Doh! :clonk:

While I am far from needing to make a decision, I am intrigued by the idea of doing something different with my car when I have to make that decision, especially some of the unusual multi-carb set-ups currently available. (http://www.inglese.com/Products/General_Motors.asp)

Is anyone out there running multi-carb set-ups on a BB?

If so, what (info and pics would be great!)

Thats a nice looking set-up bet thats cheap.:D
