tunnel rams!?!

can someone fill me in on tunnel rams?
ive been offered a 2x4 barrel about 8 inches high (roughly)
Can this be put on a stock motor? without bogging it?? ... any special buildups out there that suit tunnelrams better than others?
does t/raming have slower reaction time due to longer intake runners? or am i barking up the wrong tree

we are still amassing money and parts for our motor - any recipes for 500-600hp 90% ¼ml strip 351c t/rammed?????
we want to be naturally pushed at this time.... maybe nos later

If you put a tunnelram on a stock motor it will make a do gout of it. Tunnelram motors like a lot of rpm to work properly. 99% of the time, most motors willrun best with a single plane, single 4v intake on them. My cleveland is making between 575 and 600hp with one 4v carb on a strip dominator intake (it's never been dynoed, but based on the weight and et it should be in that HP range somewhere). I have a tunnelram intake I bought at a swap meet. I have never used it, and probably never will use it.

Tunnelrams wont directly affect reaction time, but they will make a motor lazy down low in the rpm range.

thanks vishus... do t/rams promote more revs or torque? or both? i dont know anything about them really, any articles around?????

Hate to be the spoiler here but a TR will work on anything if you take the time to tune it. It will kill some bottom end but will increase the top. I'm getting ready to put a pair of 450 holley's on a stock '78 460 in a '65 F-100. I've done this to several engines with good success. Really depends on if you want to cut a hood or not.

qtrmiler, I got a question while the tunnel ram talk is going on here. I saw a older Offy tunnel ram with a single top on it on e-bay awhile ago that kinda caught my eye. The runners looked smaller on this older manifold and I thought that with a single carb that it might work OK on my 460 which is not stock but not hog wild either. I'm going to be doing a prostreet style car and may run into hood clearence problems anyway so I thought the TR through the hood would be kinda neat if it didnt kill the drivability too much. What do you think?
