Make your mouse roar!
Think you got what it takes to REALLY let the air-fuel into your mouse motor? Maybe this setup is what you need?

Re: Make your mouse roar! (Corz)
yes it is a crossram but it''s a log style, the 2 pc ones with a lid are much nicer, there''s several of them. Offenhauser still offers the copy of the GM crossram, the edelbrock STR-10 occasionally pops up on ebay, it''s very similar only diff. is the waterneck points up instead of to the front and there''s a tad mor clearance for the distributor since plenum is rounded at the front and rear instead of with large angles. The one I like best is the SY-1 smokey ram. Do a search on them on ebay. I might pick up a smokey ram and drop in on my truck just for giggles.

Re: Make your mouse roar! (Twin_Turbo)
ALL the manifolds shown here are cross rams. Just variations on something that Mopar brought out in the early 60s. And before you "giggle" your way into installing one one, be advised they are TOP END manifolds and not made for tooting around town. They look real impressive, but you need big valves, free-breathing heads, and a stiff gear to make them perform at their optimum. They were a dealer-installed option on the Z-28 Camaro, which usually had the "right stuff" to be able to make use of them.

Re: Make your mouse roar! (Dep)
I'm quite aware of that, the crossfire manifold itself is of the same design. The offenhauser manifold works quite well on a 350, the power band is quite good (2000 up). They have a very flat torque curve, quite a nice manifold. My truck is not set up for pulling power, it makes a shame of lots of corvettes here (nothing more fun than making shame of a couple of ricers in a 'slow' truck :D )
I had an offenhauser, sold it because I went to the individual runner setup.
Here's my offy compared to a stock CFI manifold:

Re: Make your mouse roar! (Twin_Turbo)
A lot depends on what carbs you install on them. Two small 1850s are about all an average "hot" smallblock can take. You really do have to reach the 4000 and above RPM level to get full benefit of this kind of manifold. It does look impressive under the hood though :)

Re: Make your mouse roar! (Dep)
Oh yeah?? :D
How about the Fenton tripower? THAT moves some a/f!! When the front and rear carbs come on, it really shoves you into the seat! Fun, fun, fun! And it's a small block too! :lol:
I've got a pic, but it's not too good, and no host so use your imagination!!
Later!

Re: Make your mouse roar! (Dep)
who''s talking about carbs? If I were to do this I''d install 2 throttle bodies, no vac. signal problems and the FI really helps getting the power band down to an acceptable range. Also, the offy has funnel shape runners and they are reasonable long, much longer than an LT injection system.

Re: Make your mouse roar! (Dep)
oh but it has been done before :D, you''re right in that large heads and good exhaust are required otherwise it won''t run anywhere near decent.
Injection systems aren't that difficult, especially speed density. There''s a couple of crossfires running that manifold, there's a couple with SY-1s and STR-10s too. Some of those run very well, a few run like crap but that''s mainly because of stock sticks and heads.

Dep, multiple carbs is NOT keeping it simple. I think more than one, for a street driven car anyway, is too much headache. Fire away!!!!

Guess I'll go with 1 throttle body and 8 injectors and leave that fun to you. :D
