Tunnel Ram

im running a 69 455 thats been punched .30 over. currently im using an edelbrock aluminum intake with a 850 carb.... does anyone have any info or help with finding a dual carb high-rise that i could use on this. im looking of like the old tri fives, i was told something about an adaptor plate for the 455's that would enable to use mopar tunnel rams.

 

I have twin 950's on a mopar tunnel ram with adapter plates with port matched stage 3 T/A heads.:laugh:

 

would this setup happen to be for sale??

 

Yes.. Twin 4150 950 AED carbs k&n air stacks weiand 440 tunnel ram most of the carb linkage and 455 mopar plates and match ported stage 3 TA aluminum heads stage 3 roller rockers. I'm planning on pulling the motor next month. No thoughts on how I will price the package.

 

Frank what set up are you going with next

 

Stage 4's with port matched SP2 intake. Nothing too fancy. :TU:

 

Stage 4's can get pretty fancy

 

okay sounds good, when you get there just shoot me any ideas if we can work anything out. thanks

 

Charlie Evans made adaptors before moving to fords. He might have some leftover. The tunnel ram pictured here for sale is a M1 mopar. There are two types of plates, B block 383/400 fits the standard port location while the RB type fits raised port heads suchas stage3.

 

Yes I think Charlie still has adaptors. We used them to run a Chrysler STR 2x4s on a Buick. But on the dyno we never saw much improvement over the old 1969 Offy 2x4 intake that I had been using (and still do). I run NMCA Nostalgia Super Stock and some places (other than NMCA) we have to run 2x4s so I was hunting for a better intake as everyone said the Offy was junk. But after lots of trial and error and testing I 've settled on the Offy. When I was running iron Stage 1 heads I ran 2 750 AFBs and even tried 800s which ran the same. After switching to Stage 2 TA SE heads it had a slight stumble with the 750s and 800s so I went to 600 AFBs and have went the quickest and fastest with them. By our rules I can only run AFBs or 1 Quadrajet unless I can run 9.75 or quicker in the 1/4. I'm wanting to step up to more engine and run Charlie's adaptors and a Indy Cylinder Head inline 2x4 intake and 2 Quick Fuel carburetors which will be legal if I can run 9.75. Main problem with stepping up is the expense of safety clothing and license and car cert. I hate to mess with a combo that has won me 2 Championships and several races.
