I have a 68' 327 in a 31'Ford coupe and I just happened across a Edelbrock street tunnel Ram and want to run it! The motor is pretty much stock and was thinking about running two Holley 450s with mech.secodarys. My whole question is "over-carb" problems. I am sure I can take it to a speed shop yet was hoping to dial most of it myself. It has some linkage to Fiddle around with,but most of all will it work???? Thanks
Mainly depends on cam and heads but worst case scenario you can always jet it down, we set up a 406 with a tunnel ram and a 383 with 6-71 both breathing through two 450s and both ran awesome.
Holley 450's seem to be standard fare for street tunnel rams. Here is a link to recent Hot Rod Mag testing. http://www.youtube.com/watch?v=w3wkol6_7XY
My buddy runs that on his T-bucket. It runs fine except for a big bog if he jumps on it from a stand still and its really hard to start if its really cold.
You are opening a topic that has been discussed to death here. Do a search and set for title search only, not title AND thread. Do several searches using the search words as follows: Tunnelram Tunnel Ram Crossram Cross Ram You will find more reading than you have time for. Do a BUNCH of reading before jumping into this. You can bolt a tunnel ram on anything and drive it (I had a daily driver tunnel ram stock 283 engine in high school, winter and all...) However, if you want it to run right and work, there is MUCH to learn. I have 2 500cfm Edelbrock/Carter style carbs on an Offy Crossram on my 55, but it takes higher compression, bigger heads and valves, more ignition, a different cam, a stick or a stall converter and 4.88 plus gears to make it all work right (never mind the tuning...)
I ran 67 327 in model a pick up with a tunnel ram with 2x edelbrock 500cfm on. It ran champion i was get 19 mpg.
Flattery is nice, but cash is better. I could take your credit card payment over the phone or yes, I accept Pay-Pal.
