[elegance]

can anyone explain what exactly tunnel ram is.. and whether or not i can hook it to a 202 stock motor... price estimate would be good also. sorry to waste time but i was interested and didn't know

Ok, first of all heres some tunnel ram pics for a 350 chev with twin 650 hollys.

Basically a tunnel ram allows for better air fuel mixtures when running big carbs on a modded engine.

On a 202, Id like to see a 202 require something like this , I have seen a blown 202 running a 650 double pumper and it wasnt short on fuel so I could never see a 202 ever require something like this.

With a 202, go for something like triple SUs. You can pick up a set on ebay for around $400 to $500.

Tunnelrams are for V8s...

The closest thing you will get to a tunnel ram for a holden 6 would be one of those old EFI manafolds used on the VK's. These work well even though they are a bit restrictive. Set one up on a 173 9 port on lpg and it worked better than the 2bbl manifold, it had a big cam though.
